Wow 00:36:45 What's changed from 4.12? 00:38:56 EMC documentation plus Sherline's docs. 00:39:18 along with a few M$ utilities. 00:40:37 Actually, I don't know how much spam I have - it got as far as 145, and timed out 00:40:59 cleaned up two loose ends that would cause problems later on... 00:42:40 Cool 00:43:27 Well, I gotta get some shut-eye 00:43:41 * asdfqwega goes to see the taxman tomorrow 00:45:13 The private sector kind, not the .gov kind :) 00:45:37 * paul_c is busy burning CDs to mail out 00:45:50 not going to get them all out tonight.... 00:46:00 Long list 00:46:00 ? 00:50:29 20 odd names 00:51:34 I can see that would take a while 00:51:49 I'll be back around next week - hopefully with happiness and good news on several fronts 00:52:35 take care 00:52:38 asdfqwega has left #emc 01:01:38 my shop is clean again :) 01:20:27 * paul_c is outa here. 01:20:30 meep! 01:20:44 howdy robin_sz ! 01:20:48 night paul_c 01:20:54 paul_c has left #emc 01:21:38 robin_sz has changed the topic to: Welcome to the Enhanced Machine Control forum | Regular Developer's meetings every Sunday between 14:00 & 18:00 GMTgezr 01:21:38 ChanServ has changed the topic to: Welcome to the Enhanced Machine Control forum | Regular Developer's meetings every Sunday between 14:00 & 18:00 GMT 01:21:43 hi gezr 01:21:51 grr. 01:21:57 ? 01:22:08 poxy irc software 01:22:13 oh, 01:22:44 why the poxy server lets you accidentally set the topic without admin privs, I have no freakin idea 01:23:12 the channel mode lock needs to have +t added 01:23:34 shrug 01:23:37 anyway ... 01:23:40 that way a user gets a message you must be op 01:23:52 the service droid fixed the server today 01:23:53 who knows 01:23:54 hurrah! 01:24:10 your server? 01:24:13 I now have awesome computing power :) 01:24:16 yeahm new dell 01:24:35 dual proc EMT64 .. mmm shiny 01:24:56 scsi RAID and all that jazz 01:25:04 sweet 01:25:23 but do you have cold beer? 01:25:26 seriously noisy though 01:25:34 ooh, lets see. ... no 01:25:38 no beer here 01:25:42 dear 01:25:50 ouch 01:26:20 so you been working with g2002? 01:26:54 SteveStallings has joined #emc 01:27:04 yeah, a little 01:27:09 is it neat? 01:27:14 posted a wiki for that too :O) 01:27:19 its very neat 01:27:25 I dont know the main wiki site pages 01:27:36 for emc? 01:27:46 linked from linuxcnc.org 01:27:49 SteveStallings : I dont know if you got this the other day, but maybe you could try zircon in place of mirc as a windows client 01:28:02 robin_sz : oh okay :) 01:28:17 gezr: you mis-spelt wintendo 01:28:19 nope, I didn't, seems my max connect time is about 15 minutes lately 01:28:33 SteveStallings: its your firewall 01:28:47 SteveStallings : yeah, see if zircon provides you with a better connect 01:28:57 I bet you are behind a NAT firewall arent you? 01:29:09 firewall hasn't changed in months, yes I am behind NAT 01:29:38 irc and NAT often behave like that, 01:29:53 I can punch through, do you know the ports? 01:30:44 6667 01:30:51 tcp and udp 01:31:45 I dont know what it is I use for it 01:31:54 udp ? - bad, with the reliability of the net during peak hours it gets dicy 01:32:32 try using the ip_conntrack_irc module :) 01:32:58 ive not examined the protocol, I assume its TCP control and UDP for data 01:33:06 if your using iptables that is :) 01:33:34 NAT firewalls and UD{ just dont seem to get on 01:34:25 if I have to give up NAT or IRC, IRC goes 01:34:44 what client are you using, that may be all it takes 01:35:20 pinholing the firewall for IRC maybe all it takes, some more modern NAT systems have 'spplication helpers' you can dd in for things like nat 01:35:36 once a connextion is established, its maintained via the ping/pong session between the server and the client 01:35:50 they monitor the TCP forwarding and create matching UDP forwarding ... 01:36:27 gezr: except, udp is a conectionless protocol, which is where the fun starts 01:37:17 I suspect my problem is lost udp packets. We experience peak periods of 25% regularly. 01:37:42 yikes 01:37:59 all those voip weenies I guess 01:38:35 I cannot afford a good quality circuit. Both the ADSL and the cable seem to have the problem, different times of the day. 01:39:06 I can provide you with a shell and you could use a terminal client 01:39:40 its what I use, just bitchx nothing really fancy but many terminal clients exist 01:39:46 One of these days I am going to upgrade to a fraction T1. 01:40:44 winbox-(putty)---linuxbox....bitchx.....----freenode.net 01:41:19 I really enjoy havin ADSL ... 01:41:21 what, not bubblegum and bailing wire? 01:41:33 I did a full debian install in under an hour over ADSL :) 01:42:21 thats fast 01:42:30 robin_sz : so your liking debian a lot more I guess? 01:42:56 Oops, I meant to say SDSL. That is the one with the server on it. Workstation is on cable which is plent fast, but more lost packets. 01:43:23 les has quit 01:44:33 gezr: yeah, debain is my OS of choice now I think 01:44:58 actually, I could pick your debian brain here ... 01:46:15 les has joined #emc 01:46:47 I installed a 2.6 smp kernel ... 01:46:47 the old 2.4 smp kernel works fine .. uses a module called 'megaraid2' as the raid driver 01:46:47 okay 01:46:52 hmm, Im under lag or something 01:46:54 obvioisly that in the initrd, so it can bootstrp istelf etc 01:47:08 ...anyway 01:47:55 as far as i know, under 2.6, the bits of megaraid2 have been assimilated into the 'megaraid' module .. 01:48:29 but .. it still looks for megaraid2.ko, which doesnt exist, kernel painics and dies when you try to boot 2.6 01:48:50 it should be looking for megaraid.ko as best I can tell 01:48:58 ideas?? 01:50:19 I dont know much at all about a 2.6 kernel, but if its looking, then in /etc/modules/ or in /etc/modules.conf there may be a mention of the module its self, but as your stating its needed for the boot process, have you tried installing it into the kernel? 01:50:34 no, its not looking in there 01:50:44 i know this 01:50:47 les has quit 01:50:57 because ... it hasnt monted the raid array at this point 01:51:47 its still doing its bit from the mbr and initrd here ... 01:51:47 im thinking 01:51:48 les has joined #emc 01:52:20 picnet has joined #emc 01:52:24 * robin_sz watches the cogs go round 01:52:24 did you check your lilo.conf or your initrd for mentions of it? 01:52:37 lilo.conf .. this is grub 01:52:49 I have no clue how to check initrd 01:53:08 I assume the debian kernel pkg ting does someting 01:53:10 I dont know squat about grub, im reading about initrd now 01:53:24 it may not, are you just installing an apt-gotten kernel? 01:53:32 yep 01:53:40 kernel-image blah 01:53:54 that may be it, it may not know about the new kernel modes and such 01:54:28 let me read about how to at least cat out what the current initrd is, a developer who made that kernel may have included the module but not the proper load sequence 01:54:45 hmmm. 01:54:52 the module is installed in /lib/modules/kernel2.6.xxxxwhatever/whatever/megaraid.ko right? 01:55:00 yip 01:55:36 I cant see any mention of megaraid2 in the 2.6 tree ... 01:55:42 but I am a bit blind 01:56:16 les has quit 01:57:53 check your grub config file 02:01:36 hmmm, ok, i; search for it 02:01:41 wow ... 02:02:01 a bloke just got arrested for not using IE 02:02:51 seriously. locked up by the police for using lynx 02:03:04 http://www.boingboing.net/2005/01/27/jailed_for_using_a_n.html 02:03:12 right ... bedtime for me. 02:03:21 night! 02:03:24 robin_sz has quit 02:04:14 found application note on firewall, punched hole for DCC for mIRC, we shall see 02:06:13 oh shucks he left 02:06:31 looks like he isnt the only one with that issue 02:06:37 guess he does sleep sometimes 02:06:44 hahaha 02:07:13 I crashed out at 6pm cst yesterday, I was worn out 02:07:53 I have been on IRC more than usual lately only because I have been chained to my workstation running PCB layout stuff 02:08:49 I guess thats both good and bad 02:09:01 im glad your around 02:09:18 im sure you can think of a million things you would rather do then be tied to a box 02:10:06 yea, I tend to get lots of coffee, run to the toilet, anything for a break 02:10:11 im around mainly for the conversation, after a year off Ive decided to get my bike restored, a small xy table running emc, and then slowly learn how to program :) 02:10:44 I need a month of "quality time" to come up to speed on Linux 02:10:58 I figured that whenever I try to rush myself I get over loaded, so for now im just concentrating on getting the bike back together 02:11:27 linux has undergone a lot of changes 02:11:45 a year ago I would have probably knew what was robins issue, but now I cant be so sure 02:12:17 it does however look like megaraid2 drivers were excluded and some sort of kernal pause/halt exists 02:12:32 well, my last significant time in the *nix world was with MtXinu on a VAX750 02:12:58 oh wow 02:13:01 all drivers had to be compiled into the source 02:13:33 add a printer, recompile 02:14:43 oh goodness 02:48:12 im going to bed, you guys have a good evening/morning 02:48:40 nite 02:49:08 later gezr 02:50:05 A-L-P-H-A : any luck with the backlash stuff? I didnt even know you were around 02:50:23 I just got back from a friends house.. pizza... and then waxed my snowboard at his house. 02:50:32 ah 02:51:04 03jmkasunich 07halrefactor-0-1 * 10emc2/src/hal/ (hal_cmds.c hal_refactor.c): fixed a couple of warnings 02:51:05 backlash... I'm not gonna worry about it... it's 0.002 no matter what I put in... it's repeatable everywhere, and just something I can't do... it's probably the bracket flexing. 02:51:23 so I can't really do much, until I make a new bracket I guess. 02:51:59 I didnt follow the recent backlash post too much, but if Im thiking correctly, on the seimens 840D control, in its advanced upgraded modes, has a feature for backlash free hole drilling, in which every new x-y position is moved into the exact same way for every hole, reguardless of how it gets to the hole, its then repositioned to remove all backlash 02:52:44 that is neat to me. 02:53:03 I could just home all critical cuts, before moving to the next position... so always coming from one direction. 02:53:13 but... I'm not that ambitious at this moment in time. 02:53:54 well, you only have to move to the cut fromt he same direction, like get near, move x- and y- then x+ and y+ to correct point to remove all backlash and have the same load on each screw 02:54:14 but the mill works... I've machined flat a surface... reusing an industrial heat sink... machined it flat... gonna replace the heat sinks I have with that one after I measure everything on how to mount the geckos on it. 02:54:44 gezr, the backlash I do have is 0.002" on one... and 0.0001" on the other. So I'm happy enough with it... [though I would love to rove the 0.002". 02:55:07 it's small enough, that any critical parts I am gonna make, will be well within tolerances. [like brackets] 02:55:11 your milling thing basically is an up and down on your lathe right? 02:55:19 its not really a Z but an X or Y right? 02:55:57 the Y axis or centerline axis of a lathe 02:56:33 oh. the lathe... the lathe has 0.02 and 0.03mm backlash on the axes. They're compensated. 02:56:44 picnet has quit 02:56:46 I'm talking the mill. 02:57:19 the lathe works mint... works great... I can create some nice curves and everything with it. 02:57:23 oh okay, check your backlash while putting constant upwards pressure on the spindle, just from your hand, if that works, then an indicated .002 may not exist when its under load 02:57:25 :) 02:58:31 the Z axis... that's just messed... it's on that original retractable spring. works well for most cuts I've made... I'm milled 1/4" Z with 4IPM, with an 1/2" 4flute endmill... I forget the speed. 02:58:33 and if that turns out to be true, and if its similiar to the picture you showed us yesterday, just hook a spring from the housing down to the clamp used to position the spindle downward to keep an even upward pressure on it 02:59:21 and you can always just say, I use that only as a safety margin incase something fails the spindle auto retracts :) 02:59:35 I'll take some photos tonight of the mill for you... and put them up on my gallery. :) I'm too tired/full right now to do much. 02:59:55 im tired too, sounds like your having a great time with it :) 03:00:16 ill check it out tommrow, you have a good night 03:00:30 I am... I was milling simple stuff, to figure out my feedrates and stuff... but I left the speed chart for the belts (which I took off the mill) in my room. 03:01:07 I have it right here... I think I was only going 850rpm, with an 1/2" endmill. 03:01:26 I was making chips, and nothing sounding like it was working too hard. 03:01:53 did a fly cut with an 2.5" shell face mill, and it was shiny... I could see reflections. :) 03:02:01 1ipm and 850rpm could do i I think. :) 03:03:07 next time I'll spin the facemill fast, and go at a higher pace, or maybe even still do 1ipm... 03:03:19 dunno... that's why it's fun. 03:05:50 Y axis, is awesome. it's backlash is essentially none. 03:06:28 X axis, has 0.002" backlash, which I'm not able to compensate out... but i can live with that as it's repeatable everywhere. 03:07:35 Z axis, there is no precision in this "fine" quill feed handle. it's garbage essentially. But it's repetable, so it okay. 03:08:00 anyways... I'm repeating myself... so nap, and then I'll play with the mill more. 03:52:53 picnet has joined #emc 04:01:26 SteveStallings has quit 05:27:15 03jmkasunich * 10documents/lyx/Hal_Introduction.lyx: fixed a typo 05:35:47 picnet has quit 05:53:29 picnet has joined #emc 10:55:01 robin_sz has joined #emc 11:12:35 picnet has quit 12:05:24 picnet has joined #emc 12:33:57 les has joined #emc 12:40:17 morning. 12:40:41 who's good with stepper motor drivers? I just realized that I have a 5phase 0.72deg motor. And I have nothing to drive it with. 12:40:53 I'm gonna have to make my own driver... and just gonna do half step with it. 12:41:21 the issue I have is doing the half step phase input, and how much current to give each phase... 12:51:12 picnet has quit 12:55:53 meep? 12:56:19 :( 12:56:21 5 phase? 12:56:29 you need a 5 pahse driver matey 12:56:35 Can't figure out this 5 phase motor winding with a test meter. 12:56:41 nah? really? :) hehe 12:56:49 how do you know its 5 phase? 12:56:56 I could make one, if I figured out how the stupid wiring. 12:57:25 better read "jones on stepping motors" 12:57:29 I got the phases to drive. 12:57:38 sure? 12:57:46 sure its not just a 6 lead motor? 12:57:51 http://www.pastebin.com/237571 12:57:58 5 wire, 5 phase motor. 12:58:31 5 wires? 12:58:38 you sure 5 wires? 12:58:45 this is a PK569AUHA Vexta Stepper motor.

I'd be done, set... game. 12:59:51 making a driver board. 12:59:52 has someone snipped a wire of maybe 12:59:55 Vextra has complete specs on their site...I used it just a while ago 13:00:02 ahh, I get it 13:00:25 I'll call them up in an hour... to see if I can get the specs for it. 13:00:59 connect the windings in a .. pentagon shape, wire to each junction 13:01:01 or ... 13:01:14 5 pointed star and a virtual neutral 13:01:43 just feed it sine waves 360/5 degrees apart on each lead 13:01:45 hang on. 13:02:09 http://www.pastebin.com/237572 ohm readings 13:02:55 broken then? 13:03:19 http://www.pastebin.com/237573 <-- better aligned. 13:03:25 I wouldn't think so. 13:03:48 when the wires are touching, there's lots of resistance. 13:03:54 when the wires aren't touching there's no resistance. 13:04:00 resistance when spining the shaft. 13:04:02 cream-black-red looks like a 3phase 13:04:32 you'l lneed a manual 13:04:42 ive not seen a 5 phase with 5 wires 13:04:46 thats odddddd 13:04:48 being, one of the wire would go to ground, and the other two powered? 13:05:20 sorry, ive stopped thinking about it .. it made my brain hurt 13:05:46 heh. sure 13:10:53 hmm ... seems none ie/mozilla browsers are illegal in the uk 13:11:07 illegal? 13:11:12 http://www.orientalmotor.co.jp/cgi-bin/WebObjects/UPOMStep.woa/wa/F3?typeNameId=2&modelName=UPK569AHW2&frameSize=60&seriesId=UPKW 13:11:18 that it? 13:11:19 as in police, arrseted etc 13:12:19 if they catch you using, say lynx, they send a swat team round, bust your door down and haul you off to jail 13:12:26 checking 13:12:36 oh, read that a few days ago. 13:12:43 http://www.boingboing.net/2005/01/27/jailed_for_using_a_n.html 13:13:28 fsck, ive hit a debian dead end ... my mkinitrd knowledge is at its limit 13:14:38 * robin_sz submits it as a kernel bug and stops caring 13:15:23 well off to the shop for me...another day's cherry chips to be made 13:16:18 hah! 13:24:18 http://www.cs.uiowa.edu/~jones/step/types.html#multiphase Jones is knowledgable 13:36:51 I am very angry at my computer... stupid thing is freezing intermittantly. 14:07:13 http://www.orientalmotor.com/products/pdfs/F_TecRef/TecSt.pdf <-- after much hard research. 14:12:38 alex_joni has joined #emc 14:12:44 greetings 14:17:14 picnet has joined #emc 14:19:04 hello 14:19:14 hey alpha 14:19:16 5phase 5wire stepper motor FUN! 14:19:22 cool... 14:19:35 no... I gotta buy parts and make a stepper driver. 14:19:42 there seems like something cool from allegra 14:21:14 5 chips... 7407 7406 SI-7502 (allegra) SLA6503 (allegra) SLA5011 (allegra).... couple of resistors, diodes, caps... done. 14:21:26 what amps? 14:21:49 2.8amps is what's written on the motor 14:22:03 http://www.allegromicro.com/skncatlg/stepper/si-7502.pdf 14:22:10 allegra = allegro 14:31:59 looks pretty simple 14:36:40 still say those windings look broken :) 14:36:52 hey robin 14:36:57 hey 14:36:59 what's new? 14:37:16 mmm .. my debian server :) 14:37:30 working now? 14:37:43 can't get it to run a 2.6 kernel, but otherwise, yeah 14:37:51 ok on 2.4 14:38:29 the problem is with mkinitrd 14:38:30 2.4 is pretty ok ;) 14:38:36 didn't try 2.6 yet 14:38:50 can't you compile the initrd contents into the kernel? 14:39:01 I usually used the ramdisk for needed modules 14:39:08 hmm. nealry 14:39:17 nealry? 14:39:27 see, in initrd is file called 'loadmodules' 14:39:39 and in there ... is a line 14:39:51 modprobe -k megaraid2 14:40:06 but there is no megaraid2 in 2.6 14:40:12 its just called megaraid 14:40:20 ln -s? 14:40:21 .D 14:40:33 well, hmm 14:40:37 or some alias in /etc/modules.conf 14:40:42 didn;t think of that :) 14:40:50 but I don't think initrd read /etc 14:40:56 that's only later on 14:41:01 cant reaD /etc 14:41:03 or simply rename it :D 14:41:04 right 14:41:17 I usually make a initrd image when compiling a kernel 14:41:25 to include the compiled modules aswell 14:42:01 well, this is poking the current kernel to figure out what it needs to include 14:42:10 and getting an answer it cant use later on 14:43:01 yup.. I had the same problem with ReiserFs when I compiled a 2.4 lately 14:43:07 I tried mkinitrd a while, 14:43:20 but then I just compiled reiser into the kernel, not as an module 14:43:22 and it worked 14:43:30 interesting 14:43:53 the initrd is optional AFAIK 14:44:02 sorta, yeah 14:44:14 it allows using modules before /lib/modules/ can be read 14:44:24 i need to install the .config for that kernel out of debian foo I guess 14:44:29 correct 14:44:30 along with other stuff I don't know about ;) 14:44:36 its a cramfs 14:44:41 try this: 14:44:43 like splashscreen, and such 14:45:03 mount -t cramfs -o loop /boot/myinitred.img /mnt/tmp 14:45:16 I see.. 14:45:22 can you modify it? 14:45:25 no 14:45:32 cramfs is a read-only fs 14:45:37 too bad ;) 14:45:49 but mkinitrd has a lot of options if I rememberit corectly 14:45:56 it does 14:46:01 in /etc/mkinitrd 14:46:03 so you can tell it to include a lot of stuff 14:46:04 lots of conf 14:46:21 telling it to include megraid is fine 14:46:37 telling it not to include megaraid2 is harder :) 14:46:51 lol 14:46:54 I imagine 14:47:03 did you update the mkinitrd package? 14:47:11 maybe there's a newer for 2.6 14:47:17 hmmm 14:48:19 what kernel do you have? 14:48:21 how do you find out which package provides a command 14:48:23 2.6.? 14:48:37 rpm -ql | grep command :D 14:48:42 currently? 14:48:44 2.4.27-2-686-smp 14:48:44 but I think you want that for debian 14:48:53 and what 2.6 did you try? 14:49:19 2.6.8-2-686-smp 14:49:20 and 14:49:26
