Installation EMC on kubuntu 9.4/9.10

I'll be delighted to test out the emc2-sim package on 9.10 when you have it ready. Given how fast 10.4 is coming down the pike, it is probably prudent to pound on the these packages as much as possible. Thanks for all of the hard work -- have a .deb package is so much easier than a source install.

Hello John,

I think we are on the same page and as long as some discussion is welcome on the forum it might benefit everyone to post their "undocumented features" here for the forum members to discuss and then move unresolved one to the bug reporting site. This may help reduce duplicate bug reports and not overload the bug reporting site with erroneous bug reports.

Retrofitting my maho mh400c

Here is a picture of my setup using a mobo, hd, power supply, 5i20, 7i33, 2 7i37's. The Mesa boards are below the mobo. If your linear scales output the same signal as an encoder you won't need anything else. Notice the AIO 50 pin cables that go from the 5i20 to the daughter cards. Plan your installation well and get the right length cables.

for 3 analog servos +spindle, a 5I20 +a 7I33(TA) + a 7I37(TA) will do as long as the 4 servo interfaces
provided by the 7I33 (4 +-10V analog outputs + 4 quadrature counter inputs)
and the 8 1A DC outputs and 16 isolated inputs provided by the 7I37 are sufficient for your I/O needs
you can add one more 7I37 for isolated I/O if needed

In addition, 2 or 3 AIO 50 pin cables would be required

Hi Rick,

The forum is so new that I don't think we have a "preferred procedure" for that. Generally if you can reproduce a bug or suspected bug and can document how to reproduce the suspected bug then it should go on the bug reporting site. As always some discussion is welcome as sometimes you think you found something wrong but it might turn out to be a "feature".

New CPLD-based board

FesterAddams — Wed, 10 Mar 2010 23:22:27 -0800

Author: FesterAddams

Hi everybody!
Sometimes we developed our own CPLD-based board with a couple of MAX!! CPLD's & one XC164 processor on it. Board has 60 optical isolated inputs, 50 power outputs, 12 analog outs, e.t.c. We use it for automation of various machines instead of ladder logic and retrofit. Such boards also may be cascaded to increase number of I/O.
And now i thought that this board will be a good thing to interface computer w EMC2 and machine.
It seemed to me such architecture is very attractive: Control of servo-drivers through STEP/DIR, a feedback by position by means of incremental encoders, and counters of co-ordinates to program inside CPLD. Communication of the interface board with the computer through LPT or Ethernet. In this application the microprocessor is not necessary, analogue outs - too.
I will be glad to hear criticism, and even more - suggestions.

Installation EMC on kubuntu 9.4/9.10

I recently bought a new laptop and installed Kubuntu 9.10 on it.
I've been trying to reinstall the EMC2 Simulator with no success
to date. I went to:

http://emc2-buildbot.colorado.edu/~buildmaster/

loaded the appropriate APT line into my package manager and
attempted to load the emc2-sim package. I get the following compliant:

The following packages have unmet dependencies:
emc2-sim: Depends: python (< 2.6) but 2.6.4-0ubuntu1 is to be installed
Recommends: hostmot2-firmware but it is not installable

Given that these are supposed to be Beta packages for 10.4, I thought
I would ask if this issue has come up before?

Any help would be appreciated,

If you need safety, you need to use normally closed switches. That way if the wire breaks, it fails to a safe mode rather than allowing a dangerous crash.

Having said that, I've used both kinds. Recently I got some cheap SMC reed switches with LED's in them. They are normally open, but for the Sherline lathe I am not concerned.

Hello All,

It has been my experience over the years using different software that we run into "bugs" that prevent the program from performing the way we think it should. Most of the time for me at least it turns out to be the program was fine and I just did not understand properly what was going on, or there was an easy fix. Sometimes however there really is a problem.

With the possibility that some of the "bugs" we discover are not bugs at all I was wondering if it was better to post questions about bugs on the forum first before reporting them on the EMC error reporting site. What is the preferred procedure for members to follow?

Running Average in Comp

btw: a running average has to 'charge up'
the output value is garbage untill its accumulated n samples

Running Average in Comp

tom3p — Tue, 09 Mar 2010 06:08:36 -0800

Author: tom3p

i've done running averages with weighting of the new information
like 20 parts of old value plus 1 part of new divided by 21
the more old stuff in the recipe makes new stuff matter less
less stuff in the recipe makes new stuff matter more
by adjusting the the number of samples, you vary between very responsive to sluggish
its easy to imagine the new value influencing the result a lot with (1old + 1 new) /2
and not making a big diff with (20 old + 1 new)/21
maybe this is what lowpass does, but 'lowpass' sure doesnt remind me of this concept
if so, make an alias called 'runningAvg' ;)

The files you created need to be placed in the directory that the PROGRAM_PREFIX = points to. This is in the section of your .INI file.
There is more information in the Integrator Manual 7.2.2 Section. If your programs are short you might want to paste one of them to your next post. There is info on this in the How to use the Forum Section. When you get the files that you created in the right place they will have to be marked executable.

Alex,

I am not trying to defend that the camera is a bad idea. I think it's a good idea to have some form of camera function within axis rather then separate windows floating around. I personally don't mind the floating windows (I have a mac, every window is floating, currently 30 windows open)

When it comes to accuracy I think that a probe can be potentially more accurate, specially that afterward you don't have to change your bit anymore, a probe doesn't care about parallax or ultra small parts, but this is not the discussion abouth what's best.

If you setup a camera permanently you always will have some form of parallax going on. If you put the camera in your spindle then you have to change that later again for a real bit AND then do high adjustment again.

I think if we want to have some for of camera IN axis then this should also add some function like camera selection, color channel selection light that can be controller by axis using a PWM to setup the amouth of light added to the workpiece.

May be when I have some time I can add that function and supply a patch for it, unless you want to do that...

I think the camera is more accurate. In case if you use jig from one of previous post you must 1st set the jig in correct position and after that use as a touch probe. Camera give some magnification and job should be more accurate.
In my case I wil install camera permanently and use some offset from dril center so I don�t need to remove tool at all. For driling PCB the tool height can be set with naked eye. No super accuracy nedded here.

For finding center of hole in solid block the probe will be acurate and I wil use it in such case.

Potentially the probe will give you more accurate results and faster.
Also in most situations you can use the bit for the probing, with a camera you would need replace the camera with your bit again and you need to re-adjust your Z if thsi extra step is needed depends on your equipment though.

However, like I said before there are a group of people that might want or even need such a camera setup, even if just to look at the process while the machine is doing it's job so such a window within Axis can be potentially helpfull.
I would like to have the camera setup aswell, but I will make the center finder first...

I have a question for after I get this all cleared up and I can install Ubuntu and Emc2.
First, a tiny bit of history: my shop computer died. I decided to take my office computer and move it to the shop and then get a hot, new machine for my office. I generally do all of my development work on my office machine and then just transfer gcode to the shop machine.
Given all this, my "new" shop computer will start off with a working Windows XP system on it. When I install Ubuntu on it, will that file system be destroyed, or can it be saved? I plan to create a VirtualBox to run XP so that I has access to my XP network to transfer files back and forth to my Ubuntu system comfortably. It might be nice to have that file system still available also.
Can anyone give me an idea what will happen to the XP file system when I install Ubuntu?

I already see that probe/jig. Can be used but I think camera is more elegant. (and have one lying around)
I'm never use Mach (just use TurboCnc) but like some thing from it.

I'm fresh to EMC and Linux. So I still seeking and reading what can I do.

For example. Tool from previous post need some routine to execute.
It's must move to touch all 4 limits (better 6 touch's) But how to execute that code.

If I incorporate that in main ngc file then I'm forced to execute every time.
I can call in MDI mode with ocall but for now that have problems.
I like idea to have button's for that (like pyVCP extension on right) but I don't know how to link that button to execute some gcode.

stil have a lot of question to get answers.

I think this also a nice thing to have for a group of users.

I know the mach3 people has this to, and I know that if a person jumps of a bridge, we shouldn't jump of a bridge, but it can potentially be a nice thing to have. The reason I like it better within axis is that you don't have several windows cluttered around on a desktop (yes I know about desktop managers that can prevent this, but the work awkward for non tech people).

From the manual:

* The specified User Defined Command does not exist
* The file is not an executable file

http://www.linuxcnc.org/doc...sec:M100-to-M199:

What did you name the file? M101 or M101.ngc? It only needs to be named M101. I don't have EMC set up yet on this computer so I can't test is out. As Rick said if you attach the file perhaps someone can verify that the problem is not in your file. Usually it is named wrong or not in the correct directory.

I'm an EE student and have an uni project to make EMC work with CAN servo controllers.
I was looking around the web and if I got it right, the main limitation is that all the communication with hardware should be done in 200uS. So far I think this is doable (and if not, it could be slowed down a bit, this is not yet supposed to be production quality).
So I'd appreciate any suggestions on this.
The other thing is, I'd try using USB CAN controller, and I found out there is rt-usb project that should work, but I can't find anything on it. Is rt-usb dead ? Where can anything on it be found ?

Thanks a lot

I'm a bit new to emc and I'm trying to figure out how to turn some extra relays on and off. I wrote a nc file as it says in the manual made it an executable file as it says m101 m102. and it still says undefined M code used . Am I missing something here? So far I have been successful at making the machine do what I want but this has me puzzled. Any help would be great.

OK, you got a tip for a PCIe card. If your system have a AGP Card you can use some cheap ATI or Matrox Cards. Actually I use here aon my machines one Matrox MGA G550 (32MB AGP) and one Matrox MGA G200 (8MB AGP) and one ATI Radeon X300SE (128MB PCIe)

I can imagine, that it depends also on the rest of your hardware if the cards will work.

I just installed this card from Newegg and it cost ~$40. Geforce 8400 gs. http://www.newegg.com/Produ...m=N82E16814162026

Don't use any after market drivers, just use the nv drivers that are included with 8.04. I have a working Xorg.conf file that I can send you once you get the card. This is a PCIe X16 card BTW. I pretty much had to manually edit my Xorg.conf file to get it to display properly but it really wasn't that hard to do.

Hello...
With my experience of C language (close to 2 week experience :P ) I manage to strip out all "garbage" from gqcam. There are a lot of sliders and other thing's but I need only preview windov. So I added crosshair to image. I don't know how this can be done in python as I think the another tab for webcam can be great for aligning job. Touchprobe are great but can't be used to align some job's (PCB as example) So here is picture grabed from my computer. Of course image is not integrated inside axis! I just put program over axis. In this way it's easy to adjust job under 0.01mm tolerance. (I can easy see one halfsteep motion from my stepper 0.0075mm)

Is there realy none interested for that widget? :ohmy:

The hole under crosshair has 0.5mm dia (0.02")

When I did my first install with the Ubuntu 8.04 with emc 2.3.x it went smooth. Then when I was not able to see what the IRQ was for the setup of emc2 (I had disabled the Ethernet port in bios so was not able to download device manager to see the IRQ #). So then went to do a fresh install with the Ethernet port enabled and was not able to get the Live-CD to not crash during boot-up. It would start to load the kernel and then go to the ash shell and freeze. I am able to install the latest Ubuntu 9.10 and Ubuntu 8.04.4 without emc 2.3.x but not the live-cd. Any ideas? I am new to all of this and working on my linux skills as I go. I would just download emc 2.3.x but not able to get the ethernet active inside of 2.3.x but it is active in 9.10.

Any ideas?

Author: karl1

Help! I wanted to try to use the SoftDMC firmware portion of my Mesa 5i20 card. The problem is that I cannot find anywhere in the manuals, website or Googling, a description as to how to interface with the firmware. The manual describes where the bits fall in sequence and the commands needed to manipulate bits, but I am lost as to "talk" to the firmware. Am I missing something? I was assuming that once the card was recognised in the computer, one could use a software program to poke around, and check/set bits. Am I missing this software? I can't believe that there isn't a step by step instructions as to how this can be done. Any guidance would be appreciated. Currently using a Linux PC, but willing to move the card to a Windows PC if needed.
Thanks!

EMC2 errors at startup-crash

hcb — Fri, 05 Mar 2010 19:16:32 -0800

Author: hcb

Hey, John, thanks again for the reply. I went to the house today and worked on the system. I hit Google for the package and found a site with it for 8.04 Hardy. It said to use the package manager as a preferred method so I used the PM to search for the package. It indicated it would need to uninstall some components (I'm sorry, I have no idea what the were called; I figured if I hosed the system I could reload it so no need to record the info). I presume it uninstalled some other OpenGL-for-Linux flavor. Regardless, when it was done I tried running EMC2 and chose the stepper-inch profile and it came up quickly and showed me a line-art 3D image of AXIS 3D letters and sat there so it seems to be working. I will have time to play with it Sunday night when I return home again.

In the meantime, to better learn what the heck I'm doing, see if I have this right:

Mesa is an implementation of OpenGL-like functionality for Linux, similar to something else that was on my system (the Live-CD) which did not work on my VIA chipset in my PC. AXIS (some type of GUI for EMC2 similiar to (KDE, Gnome, et cetera (x windows)) is a GUI for Linux (UNIX) and as Windows 3.x was a GUI for DOS only that EMC2 is not the OS, of course) needs an OpenGL-type API to do it's graphical thing. Replacing the non-functioning OpenGL-type piece with one that works with my video chipset fixed the problem (AXIS unable to do it's thing).

Had that failed (and I've done nothing to test the setup other than see it start on screen, so it may yet fail more, once in use) I would need to change the GUI for EMC2. TKEMC is a GUI for EMC2.

This stems from the fact that the OpenGL-type technology included on the Live-CD did not implement whatever was needed to make it work on my VIA chipset. Which brings me to what I've seen in Linux before; make sure you can get a driver for Linux for your hardware. Since I'm already here, and I probably should have done this *FIRST*: is there a list of recommended/tested hardware for use with the Live-CD (Ubuntu 8.04 and EMC2 combined)? So if I decide to build a computer just for this purpose or to replace the video card on my current system I could have a 'recipe' to follow?

Thanks again.

AXIS gui - can it have a grid as background ?

grey1beard — Fri, 05 Mar 2010 13:27:03 -0800

Author: grey1beard

The title says it all really, but as I'm going backwards and forwards between writing gcode and the axis gui to see if what I've written looks right, it would be better/quicker if I could get some dimensional feedback when my trig functions need tweaking.
("Backwards and forwards" is literally true - the code gets written in the house in Textpad on XP, then a memory stick carries it out to the EMC system in the workshop, come rain or shine. Please don't suggest a network - I've got enough problems already, and the exercise is good for me :) )

If I could change the black background to show a grid would be great.
Alternatively, some means of showing the line lengths on screen might be even better.

I don't want to add yet another separate piece of software if I can avoid it, as I haven't yet found a backplotter that I can check my Axis code in that gives the same output as Axis itself.
Perhaps there is one that I just haven't found yet ;)

Hi

ill reply here also
keep the info in 1 place, this should be a fairly easy setup todo.
the linear encoders might make things fun to tune for the motors in the PID depends where these are mounted etc but it shouldt be a mission imposible.

i would pick up a mesa 5i20 (or other sutable card) and use the 7I33 for analog out (io cards as john said)

if you have the manuals for the machine your life will be very easy

emc will have no problem running your machine
im sure maybe selling some of the control boards when done from the machien will fund the upgrade no problem

So I instal "cheese" as is already known to Ubuntu. The image I got surprise me. I'm ductaped camera onto router body and set focus to aprox 5cm (2"). The image come out perfect. I can clear see movment of 0.05mm (0.002"). I think this can be very usable for manualy find edges. Touch probe can't be used for centering on flat material. So I came on idea how to include camera view in axis alone. We already have tabs for Preview and DRO. So one more tab here to show webcam?! I'm shure that this can be done just I'm not capable to do that.

Rob said I should get in the area of 10m/min with Z and 5m/min with X. The drives are not tuned up yet and I can get 240ipm with the Z, X is waiting on a belt to arrive from Hardinge. However now I get a fault on the main drive board for the axis and nothing moves. Well the spindle does go from 0-6000... Oh, in the video it was running at 40ipm as I had not even began to try and set the PID.

Try running one of the other GUI's like TKEMC until you sort out why your chip won't support OpenGL. The Axis GUI is the most demanding of the video card and has the most features. I'm a DOS guy from 286 days and Windoz until a few years ago so I still understand the learning curve can be a bit steep when you first start out.

I am going to be running EMC2 on my milling machine. It's a very custom build as far as the machine goes.

Machine has a ABEC7 spindle carrying a CAT40 taper and runs up to 8,400-8,600RPM.and utilizes a Spindle Servo. I originally planned for a NEMA34 spindle servo motor. It's gone through a couple iterations of where I had either a belt drive or a geared head.

It has three (3) axes/axis + 4th being a rotary table. I would not use the 5th Axis.

The machines table is 56" from left to right and it is13.25" from front to back and is at least 1.75" to 2.25" thick and includes T-Slots that are a tad bigger than the standard 5/8" ones you see on Bridgeport milling machines. I have a tooling plate on the table that has 1/2-20 and 5/8-11 and a few dowel pin holes. My limit switches are 33.625" apart. Ball screws are Nook & Rockford Ballscrew. Linear guidance is done by THK SHS and HSR. purchased from ebay.

As far as my experiece goes, I have built a FANUC Series 15 CNC control from parts I purchased on eBay. It runs from MasterCAM & OneCNC.
I do all my drawings in AutoCAD 2009 and save all drawings in both DWG and DXF.

I would like to pick an off the shelf servo drive, servo controller, servo amplifier and servo power supply from eBay, I am considering Parker Compumotor, Mitsubishi MRJ2 or MRJ3, Yaskawa SGD or SGM type or maybe an Allen Bradly 1771, 1388 or 1391/1394/1398 or an indramat. I admit I almost had bought a FANUC A06B-6066-H type amplifier because I've been used to FANUC.

I am builing my operator HMI panel and machine control panel. I especially need standard cnc mill/vmc operator controls like cycle /stop/start, jog, mpg, coolant on/off/auto, spindle jog/cw,ccw,auto, home, e-stop, feed hold, etc

Anyone have any suggestions on which drive/controller/amp to purchase out of the ones on ebay business and industrial? I have about $3,600 to spend on servos and controls. Servos will all be AC.

Thanks in advance.

Thanks for the reply, John. Pretty color on that Goldwing, BTW.

Okay, I did a search online about the libgl1-mesa-swx11 package referenced. It is, apparently, an OpenGL-type library/API. So, it seems that the version of whatever it is that is not working on my system is just not happy with the VIA chipset (not implemented at this time the message said). I will try installing this package when I return home tomorrow. If that fails I will disable the onboard chipset and buy an aftermarket card unless someone else can tell me what to do fix the problem.

Maybe a better question would be, if the libgl1-mesa-swx11 package fails to solve the problem, what is it that EMC2 is looking for that is being satisfied by the package on my system that is failing and libgl1-mesa-swx11? That is, if I knew exactly what package was failing (and its purpose), maybe I could seek support from the relevant source (whatever group provides that software).

Sorry, pretty much basic questions but I've been a Windows guy and DOS before that; I have very little experience with any flavor of 'nix.

And sorry about the post listing, I'll use pastebin next time.

as you will know, the CNC spindle drive that was on the mill packed up shortly after the retrofit, the spindle is now controled by an Invertertek VFD (Optidrive Plus 3GV) & brake resistor . EMC positions the spindle through the VFD for tool orientation letting the tool changer change the tool once rotated and held in position.

Hello, all, I hope someone can help me with getting EMC2 to run.

I downloaded the Live-CD with U8.04 and installed it on a PC I have. The PC was built by some local guy who used an ASUS A8V-VM mboard with built-on video. The video chip has VIA on it, VT8251. I do computer work and got the system given to me as a hand-me-down when the company using it replaced it. It ran fine when it was replaced and the installation of Ubuntu went smoothly.

When the installation was complete I attempted to run EMC2. I chose one of the plasma profiles and EMC2 began loading (the main window appeared) but then crashed. I saw that Ubuntu had a bunch of updates (198) to perform but, knowing that some updates could break EMC2 (in the notes on this website) I read around and found a suggestion from BigJohnT (I think it was, an admin/moderator) in response to someone else saying to turn off updates for the OS (System - Administration - Synaptic Package Manager - Settings - Repositories - Updates tab and set "Show new distribution releases" to Never). So I did that. After all the updates were performed (including several for EMC2) I get error still at startup (launching EMC2).

I have tried different profiles: plasma-thc-sim, plasma-thc (all three sub items), stepper-sim_inch, stepper_inch, and stepper_mm and gotten errors each time.

Looking at the errors more closely before I post this, I notice that the errors are the same (I had a different one about serial something but I closed that window already). The errors appear to be identical (at least the Debug File Information section at the end):

dmesg
http://pastebin.ca/1822843

I'm not sure but does the VIA in "DRM_VIA_PCICMD" have something to do with the video card? Ubuntu seems to be working well other than this problem.

Thank you for your help.

Tuning a Velocity Servo Drive

BigJohnT — Thu, 04 Mar 2010 04:42:32 -0800

Author: BigJohnT

To tune a velocity amp (from memory cause I can't find my notes) I think you start with:

P=1
I=0
D=0
FF0=0
FF1=0
FF2=0

Then increase the P until the output of the loop oscillates.
Then increase I until oscillation stops.
Finally, increase D until the loop is acceptably quick to reach its reference. I assume this means a reasonable following error.

Thanks

Last night I got the axis drive connected and even homed the Z axis. I can see now that the homing section of the manual needs a bit more information.

I'm waiting on the belt for the X to arrive so I can change that out and start tuning the PID.

The default P settings in the HostMot2 sample should NOT be used LOL. P=100 is way too big.

I had some tips somewhere on tuning but can't access it right now :( due to a DOA mobo.

as I made change in stepgen.c to suit my needs.

So EMC is live and kicking. But the original EMC (acessible trought menu) is still there and is not ussable for me as I use only rebuild one.
So the question is how to replace unusable one (in menu) with new (rebuild working one).
I try "sudo make install" but the answer is taht I can't do that as is build for run in place.

I want to install that and to keep source free to make other changes if I need.

Nvidia driver question?

Davenc — Wed, 03 Mar 2010 15:17:36 -0800

Author: Davenc

I installed a Geforce 8400 gs along with this driver using the package manager. It appears to be an Xorg free dirver.

NVIDIA binary XFree86 4.x/X.Org 'new' driver
These XFree86 4.x/X.Org binary drivers provide optimized hardware acceleration
of OpenGL applications via a direct-rendering X Server and supports the newer
GeForce, nForce and Quadro families of NVIDIA chipsets. AGP, TV-out and
flat panel displays are also supported.

I read on one of the information pages about latency problems using the close sourced NVIDIA driver. I'm assuming this driver is not going to have the same issues? Note that I do get the NVIDIA screen at boot up using this driver so I really don't see the difference in using this driver vs the one downloaded from the NVIDIA sight. The release version for the driver is.173.14.12.

It does appear that I'm getting some pretty bad latency when open some of the built in graphic applications like F-Spot photo manager so I'm wondering if I should even use this driver or just modify the xorg as suggested. I could not find just an NV driver when looking through the different option available in the package manager. Was I even supposed to look there at all?

Thanks

EMC wont run on Intel D945GCLF2D (X_CreatePixmap)

Kirk_Wallace — Wed, 03 Mar 2010 07:09:34 -0800

Author: Kirk_Wallace

Thanks Tome. Usually I have a monitor that will go blank or scramble when X11 comes up, but not crash applications. There must be something that DPMS(?, what I mean is the feature that reads the monitors information through the video cable) is returning to X11, which sets the video card to a bad setting. I believe you can disable DPMS in the xorg.conf file. I usually set the Horizsync and Vertrefresh to match the manufacturer's specs on the monitor, but that only helps X11 select valid monitor resolution options. Usually, crashing is caused by a bad video card driver or setting, such as selecting a resolution that the card doesn't have enough speed or memory for. There may be a way to manually set the proper video card data but X11 sure doesn't make it obvious or easy. They seem to take the Windows approach and try to Plug and Play us to death. I know it's a moot point since you won't be using this monitor, but it sure would be nice to know how to handle this when it comes up again.

I guess it shows that sometimes blind parts replacement (thrashing) can be an effective, though discouraged, troubleshooting technique.

Wow, I can't believe it. It turns out the problem was simply the monitor I was using! I took the system into a friend's office to work on the problem and using his newer lcd monitor solved the problem. Apparently, something about my old sony crt was causing problems with X windows. I suspect I could tweak the X config file to get it to work but I am not going to bother.

I wasn't even planning on using that monitor on the machine so it doesn't make any difference to me but I just can't believe I spent days (literally) working on this and that is what it turns out to be. :blink:

You should be able to use up to eight parallel ports with EMC2, so you pretty much are limited to the number of slots on your motherboard. There is nothing "off-the-self" for using RS232 with EMC2, except maybe using an external PLC.

Kirk,
Thanks for the reply. The CD and DVDs that I wrote seem to install and run fine. The checks on downloaded image are good and all the files that I examine have valid checksums. Ubuntu seems to install and run fine in all cases, everything I test works, it is only EMC that doesn't work. I am (mainly) trying the EMC2 LiveCD which is Ubuntu 8.04 and they claim that only 8.04 (and 6.something) will work so I haven't bothered to try any other releases. Not sure about tweaking the xorg.conf file, other then the attempt I made after installing libgl1-mesa-swx11, but that was according to some instructions not directly related to my problem. Perhaps I will look at that some more.

I had installed Ubuntu by itself (again 8.04) on the first motherboard and then installed EMC according to the instructions at the link you sent. I also built and installed a new kernel for SMP, but both times had the same result. I was told by people on the IRC that I should not update any packages in 8.04 after the install but I am thinking that perhaps I should look at that as well.

Thanks again,
Tome

I'm glad you got your spindle going. I don't have a clue about that kind of drive.

I looked at your Hall sensor again. Your sensor has two output pins. My guess is that only one is used, but I don't know for sure. Another option would be to make a new board similar to mine. The circuit is much less complicated, but you would need to fabricate a pcb to mount the sensors and wiring on. I can make up a schematic. The electronic parts would be around $15.

Here is Vince's encoder:

Author: tome

I have spent untold hours on this. I am at my wits end getting EMC (even just the latency test!) to run. I bought an Intel D945GCLF2D motherboard (ATOM 330) because I heard from quite a few people who had luck running EMC2 with onboard video. In addition it is listed in the "hardware that works' list (http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Latency-Test) In fact, I spoke with a couple people directly on IRC that have it running fine on this machine without problem. I have a 2GB RAM chip installed, have it plugged in to an old Sony VGA CRT, have a network connection on it, a USB keyboard and mouse, and that's it.

I thought the first board might have been faulty so I returned it and got another, it has the same behavior.

The problem happens if I boot it from an attached CD Drive, or a USB memory stick, or a 100G sata disk. I used the most recent LiveCD, burnt to disk from a Mac. I also burnt a CD from another Ubuntu 8.04 machine which does that same thing. From that second CD I installed onto the 100GB sata disk.

I have played with the bios settings (there are really only a couple settings that might matter) to no avail.
On my first motherboard I installed Ubuntu 8.04 separately and built the SMP kernel according to instructions found in the forums and still had the same problem.
I tried installing libgl1-mesa-swx11 and modifying /etc/X11/xorg.conf, still the same problem.

Here is the problem:
If I boot the machine Ubuntu comes up fine and everything seems to work. If I select Applications -> CNC -> Latency Test, the machine seems to hang for a couple minutes (can't do anything in the UI) and then returns without, apparently, having done anything. If I then open a terminal window and run "latency-test" at the command prompt, I get: "Realtime already running. Use 'halrun -U' to stop existing realtime sessions."

If, upon a fresh boot, I open a terminal window and run "latency-test" I get this:

tome@Gort:~$ latency-test
Waiting for component 'lat' to become ready........................................................................................................
X Error of failed requst: BadAlloc (insufficient resources for operation)
Major opcode of failed request: 53 (X_CreatePixmap)
Serial number of failed request: 271
Current serial number in output stream: 588

Someone on the IRC suggested that since this is an X Windows error I should try a PCI video card instead of the on-board video. But I bought the darn thing to run on-board video, I don't want to plug in a stupid card I don't need! Any ideas what this error is and where I might go from here?

While pondering what parts to order for the turret I moved on to the spindle. I can get it to go forward with M4 and backward with M3. The output of the 7i33 is reversed of what I'd expect. AOUT2 is -v for M3 and +v for M4. If I reverse the wires then both M3 and M4 go backwards. If I invert IO Pin 019 (P2-39): PWMGen #2, pin Out0 (PWM or Up) (Output) it runs at about 4 times as fast as commaned. If I invert IO Pin 020 (P2-39): PWMGen #2, pin Out1 (PWM or Up) (Output) nothing changes. The drive is a Fanuc digital AC spindle servo drive A06B-6055-H106 if that helps.

I got it fingered out I had to reverse the scale to get it to turn the right way. I'll see if I can make some kind of diagram on this...

Well, I've managed to get the best of three with AXIS, and now have a parabolic curve meeting its mirror image in the centre :D
So at least the bottom serif is now done, but not quite dusted.

One thing I've noticed, and here's a small bit of code to illustrate the point -
#1=0
O100 WHILE
g01 x y
#1=
O100 ENDWHILE

Running this in the AXIS gui, the curve only goes from x0 y0 to x0.171 y0.0855 , rather than x0.18 y0.09.

Is this correct ?
I assumed the "less than or equal to" would finish when #1 reached 0.18 but I've found that I need to add a line of code to get the curve to where I expect it to finish.

Any comments ?

Well, solved that one by paying more attention to the nested brackets :)
However, though AXIS now accepts the lines I've written, the gui shows a pretty weird plot, and not what I was expecting.

The four lines plot the expected parabolic curve, cutting in ccw direction, ramping down.
I then move over to the right, then plot a mirror image back towards the first, cutting cw, last four lines.
This is where it goes wrong.
My code for a clockwise cut produces garbage, so I'd be gratefull for some help again.

I think the 613SS4 max is 20 Volts, and if the Tantalum capacitor is rated 24 Volts, usually the circuit is run way under the maximum in order to have a safety margin. I would guess your encoder board is meant to run with 12 Volts.

The 7i37 looks like it will take up to 24 Volts. You should check with Peter (from Mesa) to make sure but I think the inputs are just like a 4.4k Ohm resistor and an LED in series. Sorta like this:

(Click on image for lager version)

You need two wires for each encoder output. One to supply the signal, another to complete the circuit to the encoder board's ground.

I would think that you could do a lot of testing before ordering parts. It may be the burnt capacitor is the only bad part. I'll need to do a little more research to find an equivalent for the 613SS4.

Probe Hole center

Hello...

I write old fashion 6 hit probe hole center routine.
1'st I jog machine into hole (routine doesn't change Z axis)
As routine works I don't like some aspects as is.

1. The curent fixture offset must be X0 Y0 (G38 doesnt work with G53)
2. Machine limits must be typed inside program (how just to copy from INI file?)
3. Machine leave in center on hole. I want to see diameter and excentricy too.
(print, ....) work if I start emc from console and output is to console.
How to output that in AXIS window like (MSG, blahblah)

F200 ;set feedrate for probe

G30.1 ;Save current coordinate
G38.3 Y285 ;Scan +Y limit
#100 = #5062 ;Save +Y limit

The 613 looks like it has a 20 Volt max. The LM324 maxes at 32 V.

I am unfamiliar with this circuit, but it might be like the right half of this ADC:

http://www.opamp-electronics.com/tutorials/digital_theory_ch_013.htm

The Hall sensors would replace the left half and feed the diode array. The diode array would then feed the op-amps which would clean up the array output. A priority encoder chip seems to be much less complex, but you got whatcha got.

To trouble shoot, you can measure resistance across the power leads to see if the power input is shorted. If it is shorted pull suspected parts and test the power pins and replace the shorted chips. Check that the diodes conduct in only one direction with your meter's diode resistance setting (looks like -i --

Oops, and the Hall sensors are sensitive to the North (or is it South?) end of the magnet, so if you test your sensors with the wrong end, they won't work. Just turn the magnet over and try again, any magnet should do. And don't forget to tighten the magnet down when you have finished tuning the encoder.

I forget how the chip works, but I think the outputs only sink current, so a pull-up and voltage source is needed. I used 24 Volts and used an opto-isolator to convert to 5 Volts at my controller inputs. The optos are labeled "Turret Input V Converter" here:

I forgot to mention, I set the magnet so that the current tool number shows towards the machine front on the carriage. I originally set it to show towards the head stock, which is also the actual tool location, but I found it much easier to check the current tool number if it pointed out towards the operator. I used a Sharpie to number the top of the table for the actual tool positions. In other words, if tool one is current, tool one points towards the headstock, the Sharpie number is towards the headstock, but the table skirt number one points out the front of the machine towards the operator. I could not find anything in my Hardinge documentation that covers how the number should be set, so I just did as I pleased.

Someone has been busy. The burnt capacitor (C1) has a polarity like batteries and diodes. The tapered end indicates which way to orient the part. There should be a plus sign on the board showing which way the tapered end goes. It may be that the power was hooked up backwards at one time. Or the capacitor just failed from age. If the power was hooked up backwards, other things could be damaged. Here is an example:
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=718-1431-2-ND
http://www.vishay.com/doc?40019

Since you have a single chip, it might be this 10 to 4 priority encoder:
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=296-14247-5-ND

I remember when IC's were the hot new thing, that only the military could afford. The 10-bit chip probably wasn't available when they made my board.

I believe the silicone seal in the holes, where the cables enter, is not original and was used to try to keep the oil out, but the only way I know to do this is by replacing all of the worn o and x-rings in the turret assembly. I got all but the extra large x-ring that goes around the table skirt from Mcmaster-Carr. I had to buy minimum quantities on some, so I can send you some of my duplicates. The previous owner said he had to replace a good number of seals every few years. Replacing the seals made a big difference in how well the turret works. I'd leave the silicone out so that if any oil gets in, it has a way to get out, and so that venting air has a way to get out with out blowing any seals.

The magnet holder is not indexed to the shaft. I left the screw a little loose to tune the magnets position so that the sensor would trip as early as possible but remain tripped when the table parks. I needed the early trip so that the software and stop mechanism could activate before passing the selected tool position. It's like trying to grab a ring on a carousel, if you miss the ring, you have to keep going around until you get it. I need to add time-outs to the component so that if something goes wrong, the turret won't turn endlessly.

I wrote the turret component because I didn't want to learn ladder logic and it is much more direct. You can use it if you want. Just download it from my website:
http://www.wallacecompany.com/cnc_lathe/HNC/emc2/turret.comp

You will need to use Synaptic to install emc2-dev (or emc-dev?). Then use the command:
"comp --install turret.comp"

This link covers the command:
http://www.linuxcnc.org/docview/html//hal_comp.html#r1_12
http://www.linuxcnc.org/docview/html//hal_comp.html#r1_12

But it looks like a lot has changed from the last time I looked through the documentation. There may a better way to install a comp. When the comp is installed, the new HAL pins show up and can be connected appropriately.

I just remembered the park sensor needs to be added to the turret comp. Currently, the tool-changed signal gets invoked when the stop state is invoked. The park sensor should be checked first before sending tool-changed. Plus the air pressure sensor should be checked too. My problem is that the turret works fine as is, so there is less incentive to complete these features.

When I took the magnet off I noticed that there was not any key or any other means of lining up the magnet to any specific orientation. Is it just trial and error to get the magnet set so it will drop and lock at the right place?

Oh my and the turret comp is neat. Is it in 2.4? or did you add it locally? As many of these Hardinges that are out there it should be part of EMC I think if it is not all ready.

Dual booting Linux w/Emc2 and Windows 7?

I'm putting together a new system for myself. It has an AMD Phenom II X3 processor, a terabyte main disk, and 2 gig of main memory. I have installed Windows 7 on it which is running pretty nicely. I want to run Linux on the same machine and I'm trying to decide whether I should set it up for dual booting or whether I should should install VirtualBox and run it in a VirtualBox window. I'm not going to be actually driving a CNC machine with this computer. I have a separate shop computer for that. But I may be running Emc2 simulations on this one. Does anyone have any advice for me as to which approach would be better?

BTW, I will be running my shop computer in just the opposite manner. It will be running Ubuntu 8.04 with Emc2 to drive my CNC router. Then, when I need to, I will open a VirtualBox window and run Windows XP in it. I will need to do this particularly when I want to communicate with my home LAN. My networking software, called Network Magic, is great but it only runs on Windows PCs.

Anyway, any comments or suggestions you can give me would be greatly appreciated.

Thanks. I didn't know that halui worked that way with the override.

My encoder had the same rubber covering, but it was falling off, so I removed it. I figured removing it wouldn't make things any worse, so far, so good.
I made new cork gaskets for the cover and installed o-rings and bushings under the cover screws. The area under the turret table was venting air leaks and oil into the encoder area, so I had to fix all of the air leaks. There are two normal air vents in the system, which I think are placed at the ends of the air passages for carrying the air/oil to the ends of the lines. These vent outside though.

You should be able to fix your encoder board fairly easily. The encoder chips are still available:

You would most likely need more digits to get a reasonable resolution.

Using a quadrature reduces the number of wires, but you need to initialize the encoder before use.

Another option is to use something like an Attiny microprocessor to convert the encoder to SPI. Your Mesa card has an SPI feature, but I don't know its status. I need to get a Mesa card so I can try this out.

Axis Hangup!

Here are misunderstanding I think...
I Know that axis limits are in INI. I wrote that. But how to read that value inside Gcode?
I know that #5061 to #5070 are probe variable.
But how to determine current position (before probe move?)
So let's go trought example.

I jog machine inside some hole. Now I want to find center of that hole.

1. Remember current coordinate (how to do that?)
2. Go slow Y+ from current position until probe hit or soft limit reached (remember position #5061.....)
3. Go rapid to coordinate from step 1 (back to start)
4. Go slow Y- (same as step 2)
5. calculate midpoint from step 2 and 4 and go rapid here

6. do same thing for X axis (this is precise)
7. repeat again for Y axis (now Y is precise too)

show message that's done and show diameter too...

Holecenter program's I found all require to tell hole diameter and position. I'm shure that's not necessary. Just don't know how to deal it.

Slavko.

Hi yoyoek1,

it looks a lot like the program, thank you for sharing.

Hooked up the MPG and a few other things today. Worked several hours the other night on my feed override switch to get the binary output correct only to find that I can't use that with EMC :(

Hooked up the MPG to the 7i33 card encoder input then set the jumper to TTL. In my hal file I send the count pulses to the axis.n.jog-counts for both axis. Then the enable bit can be set to none, X , Z or both for chamfers via a radio button until I get time to install a proper switch near the MPG.

Maybe some photos this afternoon.

As I've seen in your xorg.conf your hsync is set to a max of 48 kHz
For 1280x1024 you need settings like the following.

(II) MGA(0): Configured Monitor: Using hsync range of 30.00-82.00 kHz
(II) MGA(0): Configured Monitor: Using vrefresh range of 56.00-76.00 Hz

For 1024x768 it should be enough if you have hsync of 72 kHZ

You can read the current position after the probing from #5061 ... #5069
You can get the probing result from #5070
The axis limits are in your INI file

You can use G90 and an end position before the limit point.

The idea of code is to make move until probe hit object.

As position is not known I just make progres until get hit.

If I want just one move then move should span trought entire table. But If the probe is in midle of table I got soft limit error.

Hello...

Here is code that hangup Axis.

o do
G38.3 Y1
o while

Seems that axis dryrun that code and make infiniti loop as #5070 parameter is not updated (probe trigered)
How to overcome that?

I was able to get my graphics sized right by putting the size in millimeters for my 15" monitor
in the xorg.conf file under the Monitor section.

DisplaySize 300 210

I still have garbage on boot up and my monitor telling me I am not in 1024x768@ 60
probably because it says 72 now in the refresh rate but everything is working.
Maybe I can play around and get the monitor to get the proper size signal.

I would stay away from the ATI HD 4350 pcie card. Probably forcing a square peg in a round hole here.

eg to gcode stops and ask for some veriable and after that to use it. For example to program stops and ask for radius of circle to make hole for example.
I come from TurboCnc and there was command
Ask #variable ;text prompt

is there something similar?

And other question is how to put current X (or Y..) position into variable?
somethimg like

Learning to layout simple code ?

Author: grey1beard

Well, I got it to show me the code in the AXIS gui, then I cut the code !!
Hardly suprising though that the result wasn't quite what I was hoping for.
Oh well, plenty of time to learn, I hope.

Fundamental problem I'm trying to get round is not being able to drive the cutter in a curve in three axis all at the same time.
So it seems that I'm going to have to generate code that increments the curve as a series of 2D curves with Z as a series of short steps.
Rather than write out a vast number of lines of code, is it possible to enter a mathematical expression that is then solved for a given number of steps, before moving on to the next lines of code ?

A pointer to any real examples would be most gratefully received.

I just set up a Dell Precision 4100 desktop. This one has a single 1 GHZ processor, 512 MB of memory, an IDE hard drive (I put in a brand new HD). I can easily upgrade memory to 1 GB, since according to dmidecode, I can have up to 2 slots of 512 MB each. 1994 bogomips.

Two questions:

1) Is it adequate to use with a Bridgeport Series II interact 2 knee mill
2) Do I need to have 1 GB of memory or is existing 512 okay?

This is an old POS desktop that I had, but the plus is, I already have it and it has plenty of PCI card slots.

When not CNCing, I will just use it as a general purpose garage computer that is networked with the rest of my home network (NFS, etc).

I already installed the standard EMC2 Ubuntu install.

Non-trivial kinematics problem

step4linux — Fri, 26 Feb 2010 04:47:14 -0800

Author: step4linux

You need to create a new kinematics c program.
Take one of the examples from EMC src/emc/kinematics and modify it.
I used trivkins.c as a base.

Once you created your c-file, lets call it mykinematic.c, you enter
comp --compile mykinematic.c
This will create mykinematic.ko
Install it by
sudo cp mykinematic.ko /usr/realtime-2.6.24-16-rtai/modules/emc2/

Modify the hal file
replace
loadrt trivkins
by
loadrt mykinematic

thats the procedure

another example you find here: http://code.google.com/p/emc2hotwinch/

PWM not quite working (trying again)

gordoflash — Thu, 25 Feb 2010 10:32:36 -0800

Author: gordoflash

Hi, I have installed the EMC2 with the Ubuntu live CD and have successfully got my mill to move all 3 axis.

I use a Digispeed from Homann Designs to control a VFD.

Using the Step Config Wizard and reading the Integrator Manual V2.3, I have the following functions working on my mill.

Move all 3 axis.
Find Home and limit switches.
ChargePump.
Estop.
PWM for the spindle.

My problem with the PWM is that when I type into MDI "S1000 M3" The spindle works ok, if I type "S1000 M4" I get the correct signal to reverse the VFD but there is no PWM signal to the Digispeed.

The Integrator Manual says to do this--

loadrt pwmgen output_type=0
addf pwmgen.update servo-thread
addf pwmgen.make-pulses base-thread
net spindle-speed-cmd motion.spindle-speed-out => pwmgen.0.value
net spindle-on motion.spindle-on => pwmgen.0.enable
net spindle-pwm pwmgen.0.pwm => parport.0.pin-09-out
setp pwmgen.0.scale 1800 # Change to your spindle�s top speed in RPM

But the Step Config Wizard produces this--
*** highlights areas I'm not sure about that differ from above.

loadrt pwmgen output_type=0
addf pwmgen.update servo-thread
addf pwmgen.make-pulses base-thread
net spindle-cmd <= motion.spindle-speed-out => pwmgen.0.value ***
net spindle-enable <= motion.spindle-on => pwmgen.0.enable ***
net spindle-pwm <= pwmgen.0.pwm ***
setp pwmgen.0.pwm-freq 50.0
setp pwmgen.0.scale 7000.0
setp pwmgen.0.offset 0.0
setp pwmgen.0.dither-pwm true
net spindle-fwd motion.spindle-forward => parport.1.pin-14-out
net spindle-rev motion.spindle-reverse => parport.1.pin-16-out
setp parport.1.pin-01-out-invert 1
net spindle-pwm => parport.1.pin-01-out

This system is working on a demo version of Mach3. I hope to get my mill working correctly on EMC2 as from what I've seen it's smoother motion and cleaner screen layout appeals

I can attach the hal files if more info is needed.

My next challenge is to get my pendant functioning.

Thanks

Automatic Homing after Toolchange

Author: tenaja

I am certain it is possible... however, wouldn't it be less time consuming to just make a fixture for setting the depth of your drills? (Or loosely insert them into the holder in the mill, go to "0", then tighten the drill.)

Alternatively, you could measure the extension of each drill with a caliper and edit your tool file accordingly.

I mostly suggest these alternatives because I know how slow the typical rapid speeds are. The fixture will be the fastest way in the long run, if you repeatedly set up new drills. The second method is great for low volume, and the third way is kind of an in-between compromise.

Non-trivial kinematics problem

subtractive — Thu, 25 Feb 2010 05:18:20 -0800

Author: subtractive

I have built, and am running a 3 axis cnc router, with another machine build on the way. The
control software, in FreeBASIC, gives excellent motor speed and positional accuracy. Trajectory
planning and constant feed are the main missing features.

I have known about Linux/EMC for a number of years, and recently took advantage of the user
friendly CD install, that provides Ubuntu 8.04 and EMC2. In addition, the Config Wizards for my
servo motors, motor drivers, limit switches, etc., were straightforward and must be praised by
anyone who uses them. The whole software package, a result of many years work by many people,
is a credit to you all! There are two computers, with suitable latency test results, both
loaded with EMC2 ready to run my routers. If my machines was using trivial kinematics in all 3
axes, that would be the end of it!

The machine z axis is trivial with respect to the Cartesian z axis. The Cartesian x and y axes
are handled, mechanically, by two separate rotary axes, similar to a SCARA robot, but not the
same!
My intention was to insert my own non-trivial equations into the C functions that make up a HAL
component. The learning process is rewarding when you know what the goal is. I am entirely
self-taught in this whole project and my programming skills are limited to using one of the
BASIC dialects. I have tried in the past to move on with other languages but had to give up.
There is just too much unknown syntax and terminology for me. There is no question that EMC2
will be running my machines but I am stuck and need rescuing. Would someone help me please?

Hi all, I am another newbie to cnc and am very excited about this community and the stuff cnc can do. I just took delivery of this model of a chinese 4 Axis TB6560 CNC Stepper Motor Driver Board. Well after a 3 week delay due to customs in lisbon! Had to pay import tax before they would release it.

The board is up and running but I cannot decipher the chinglish manual. I want to know what they mean by X enable Y enable and Z enable in the the parallel port setup step.

I use Ubuntu Live 8-04 and EMC2 and these choices dont exist in the Stepconf wizard of EMC2.

The definition of 1-PIN 25 of Parallel Interface in the English user manual document says:
PIN2 Spindle motor
PIN4 X Enable ????
PIN1 X Dir
PIN16 X Step
PIN17 Y Enable ????
PIN7 Y Dir
PIN14 Y Step
PIN5 Z Enable ????
PIN6 Z Dir
PIN3 Z Step

I tried using the Step and the Direction options in place of Enable - ticking and unticking the invert box. Limited success so far - Im sure something isnt right.

Any help would be welcome. Also Im thinking of using a 24 v 10 a power supply but I dont seem able to find one under 300 euros. Ideas please...

Hello...

I'm have homemade stepper driver and have phase inputs. The input to driver is 3 bit wide and is simply binary count from 0 to 7. After thinkering I modified stepgen.c and append my sequence to lokup table so modified part of stepgen.c is now like

/* lookup tables for stepping types 2 and higher - phase A is the LSB */

static const unsigned char master_lut = {
{1, 3, 2, 0, 0, 0, 0, 0, 0, 0}, /* type 2: Quadrature */
{1, 2, 4, 0, 0, 0, 0, 0, 0, 0}, /* type 3: Three Wire */
{1, 3, 2, 6, 4, 5, 0, 0, 0, 0}, /* type 4: Three Wire Half Step */
{1, 2, 4, 8, 0, 0, 0, 0, 0, 0}, /* 5: Unipolar Full Step 1 */
{3, 6, 12, 9, 0, 0, 0, 0, 0, 0}, /* 6: Unipoler Full Step 2 */
{1, 7, 14, 8, 0, 0, 0, 0, 0, 0}, /* 7: Bipolar Full Step 1 */
{5, 6, 10, 9, 0, 0, 0, 0, 0, 0}, /* 8: Bipoler Full Step 2 */
{1, 3, 2, 6, 4, 12, 8, 9, 0, 0}, /* 9: Unipolar Half Step */
{1, 5, 7, 6, 14, 10, 8, 9, 0, 0}, /* 10: Bipolar Half Step */
{1, 2, 4, 8, 16, 0, 0, 0, 0, 0}, /* 11: Five Wire Unipolar */
{3, 6, 12, 24, 17, 0, 0, 0, 0, 0}, /* 12: Five Wire Wave */
{1, 3, 2, 6, 4, 12, 8, 24, 16, 17}, /* 13: Five Wire Uni Half */
{3, 7, 6, 14, 12, 28, 24, 25, 17, 19}, /* 14: Five Wire Wave Half */
{1, 2, 3, 4, 5, 6, 7, 0, 0, 0} /* 15: CAA MODE */
};

static const unsigned char cycle_len_lut =
{ 4, 3, 6, 4, 4, 4, 4, 8, 8, 5, 5, 10, 10, 8 };

static const unsigned char num_phases_lut =
{ 2, 3, 3, 4, 4, 4, 4, 4, 4, 5, 5, 5, 5, 3, };

#define MAX_STEP_TYPE 15

Now I have no clue how to update that this to be included in next relase (I don't want to recompile each relase to work with my driver)

I have better idea for other's too.
Maybe is possible to make step_type 15 custom. So when I startup stepgen with

loadrt stepgen step_type=15,15,15

to use something like

loadrt stepgen step_type=15,15,15 step_phases=3 step_cycle_len=8 step_phase_table 1,2,3,4,5,6,7,0

In this way all other phase sequences can be supported.
I'm just not a C programmer to do that.

Is there some herro to do that?!?

Thanks

Zig — Wed, 24 Feb 2010 21:38:36 -0800

Author: Zig

A number of things have happened to prevent me from progressing with the experimentation.. that is till now.

I am in the process of building a couple of frequency to voltage converters ( tachos).

They will receive encoder quadrature signals from the IO card and generate analog velocity signals ( +/-10V) to provide velocity feedback signals to the servo amps.
The servo amps can operate in both voltage and current modes ( switch selectable ) .

There is a small delay in the tacho circuit of about 3 ms or more precisely the time constant of the tacho circuit is approximately 3 ms. I suspect this may present some problems during acceleration and deceleration phases.

I wish to set the motor acceleration to about 10 m/s^2. While this seems reasonably high the only load the motor will push is a work platten of about 10kilos and the motors can provide thrust of 30 lb continuous and 90 lb at 10% duty cycle.

Production speed of 100mm/s is present target.

Hope to have some additional info on the tach feedback performance during the coming week.

thumping at index when homing

Hi all,
I am using EMC2 (the version is 2.3.4)for two weeks now,the homing type is using switch&&index, there would be a thump when the machine back off to the position of index,can anybody help me ?

Automatic Homing after Toolchange

daniel79 — Wed, 24 Feb 2010 15:49:14 -0800

Author: daniel79

Hi!

Im using EMC2 now for two weeks and I really like it. I use it mostly for milling and drilling PCBs with my selfbuild CNC mill.

And here comes my problem:

For drilling my PCBs i have to change the drill-bits quite often. Unfortunately my bits have no stop-ring (don't know the right word, hope you understand) So every drill-bit has a different unknown Z-Offset.

And here comes my idea:

Everytime EMC gets a change tool instruction the following is done:

- go to a specific position XYZ
- wait for user toolchange
- z go down until a button is pushed by the end of the drillbit
- calcuate the new Z Offset
- continue the programm

Is this possible in any was?

It's good to know that it is or will be possible to do this.
As I urgently need to replace my broken Heidenhain controller (the milling machine can't work in manual mode without it), I will finish my micro-controlled board first and use it but without EMC. Once done, I could start playing with EMC and try to solve the DAC problem).

Thank you for your replies. They were really useful to me!

Nvidia driver question?

Davenc — Wed, 24 Feb 2010 14:56:03 -0800

Author: Davenc

Thanks, unfortunately I believe I got the wrong video card that isn't supported. The card is supported but not in a regular PCI slot. I didn't see the fine print about not supporting regular PCI grahic cards. The card works but provides only 800 by 600 resolution and it doesn't show up in the hardware mode. I should have gotten the PCIe version of the card so it looks like another search on newegg for a low profile video card.

On the latest Live-CD compile are the Nvidia drivers already in the build or do they have to be added? I'm new to Linux and Ubuntu. I'm planning on adding a video card tonight since my MB has one build in with the system RAM and just wanted to know what to expect as far as installation goes. I've read most of the tutorials but nothing pertaining to the Live-CD compile and Nvidia drivers.

"Unknown symbol" message may be related with the kernel modules dependencies.
If so, you need to regenerate the kernel module dependencies as described in
http://wiki.linuxcnc.org/cg...dule_dependencies

(But this is for Debian Lenny. The paths can be different in your system)

Then it's needed to compile EMC again.

Actally I have downloaded emc2_2.3.4-1.tar.gz from sourcefourge.net and now
I will build the stable version right now for my SMP RTAI kernel.

If that does not work I will compile the SMP RTAI here on my sytem.

Thank you very much for you help. I think I will need more till my SMP RTAI is running. ;)

#3=300 (Feed )
#4= (Z at serif end)
#5= (Z at full depth)

g00 x y Z#1 (letter home)

g01 x y F#3 (straight cut)
g02 x y Z#5 I J F#3 (first arc)

I'm not sure if AXis counts gaps as lines, so I've posted possibly one too many.

Hello..

I have cnc&controller perfectly work with TurboCnc. But I realy want to try EMC (I want CV working).
As my driver is phase driven and (my) phase sequence isn't supported by default I decide to write my own.

I have ubuntu 8.04 and emc2 (isn't recent one - aj07 EMC ver 2.2.5 ) and I folow wiki how to build from source.

http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_with_EMC2_package_already_installed

I got trougth proces without error. But something is still wrong. When I execute emc I got that version 2.2.5 is running but I was download version 2.3 and compiled.
Is there some missing step?

Exact procedure:

sudo apt-get build-dep emc2
sudo apt-get install build-essential autoconf

sudo apt-get install git-core gitk git-gui
git clone git://git.linuxcnc.org/git/emc2.git emc2-dev

Oh OK, just one axis. The problem with short delays is that without
hardware support they would have to be done in the driver
(and busy-waiting in the driver is frowned upon as it wastes CPU)

I expect to work on twiddler after I finish the resolver module (which is a fair amount of work)
There may be some other solutions to do what you want. I'll give it some thought.

Quadrature output (ULN2803 type) - how to?

PCW — Tue, 23 Feb 2010 19:50:10 -0800

Author: PCW

Doesn't look too bad
for example starting with core_stepper.hal, you would change the

loadrt stepgen step_type=0,0,0 to

loadrt stepgen step_type=9,9,9 (for example and assuming have 3 axis and the pins for 3 axis and half stepping)

then in the section that assigns step+dir nets:

net Xstep <= stepgen.0.step
net Xdir <= stepgen.0.dir
net Ystep <= stepgen.1.step
net Ydir <= stepgen.1.dir
net Zstep <= stepgen.2.step
net Zdir <= stepgen.2.dir

you change to nets appropriate for 4 phase outputs:

net XPA <= stepgen.0.phase-A
net XPB <= stepgen.0.phase-B
net XPC <= stepgen.0.phase-C
net XPD <= stepgen.0.phase-D

net YPA <= stepgen.1.phase-A
net YPB <= stepgen.1.phase-B
net YPC <= stepgen.1.phase-C
net YPD <= stepgen.1.phase-D

net ZPA <= stepgen.2.phase-A
net ZPB <= stepgen.2.phase-B
net ZPC <= stepgen.2.phase-C
net ZPD <= stepgen.2.phase-D

Then in a new file using standard_pinout.hal as an example
change the stepgen net connections to use the new 4 phase nets
instead of the old step+dir nets
( and disconnect any nets that used the same parport pins)

Thank you for your reply PCW!!!!
The Maho MH400P is a point to point milling machine. There is one common drive used with the 3 axis. The active axis is selected with electrically switched clutches. Consequently just 1 DAC is needed. I'm not sure the delay will be an issue. It's just a question of few us (10us max) to send the data to the DAC through the micro-controller and anyway, the bandwidth of the DAC would be the limiting factor (20kHz @16 bits).

Twiddler looks promising!!! Any idea about when it will be available?

"starting with a known working configuration and then editing it to support your

This is exactly what I tried! First I tried to find some compatible hardware runnig on EMC. One of these is the ETCH CNC
http://axis.unpy.net/etchcnc
from Jeff Eppler. I asked the autor for config files but no answer.

The second one project (I found) with compatible HW is described here:
http://www.bluedental.pl/im...MCHTR_PracaP2.pdf
BTW very interesting project!
I took the fragments of code and tried to complete missing parts. No luck...
At least I have an basic idea about main differences from step/dir config.

IMHO there is no easy way to take for example config files for step/dir HW and modify them to 2803 type because the differences are huge. Definitively not with my skills nor "step by step".

PCW — Tue, 23 Feb 2010 10:17:10 -0800

Author: PCW

That fairly awkward to do, especially with the delays. Also if you have many axis, this will use a lot of pins (unless you share the databus) If you really want to use parallel DACs, probably a specific FPGA configuration with a output state machine would be needed. This _may_ be supportable by a new HostMot2 module I'm working on (twiddler), that embeds a simple I/O processor in the FPGA and presents a simple set of 32 bit interface registers to HostMot2.

PCW — Tue, 23 Feb 2010 08:01:39 -0800

Author: PCW

Yes, you are probably better off starting with a known working configuration and then editing it to support your
hardware. (Your step mode and pinout may differ for the example config)

Edit a step at a time so you can find and fix errors as you go

I think this is a more likely to get you going than starting with some random config.
