03:48:19 <CIA-8> 03jepler * 10emc2/tcl/bin/pickconfig.tcl: If a directory was in the list twice, it led to an error.
03:48:52 <CIA-8> 03jmkasunich * 10emc2/src/ (4 files in 2 dirs): 
03:48:52 <CIA-8> added rtapi_get_clocks() to RTAPI. It turns out that the RTAI function behind
03:48:52 <CIA-8> rtapi_get_time() is dog slow. HAL was using rtapi_get_time() to measure how
03:48:52 <CIA-8> long each block takes to execute, but the 'time measuring' function was actually
03:48:52 <CIA-8> taking far longer than the thing it was supposed to measure. The times
03:48:52 <CIA-8> displayed by HAL as .time and .tmax are now in clock cycles instead of
03:48:56 <CIA-8> nanoseconds, but the speed improvement is worth it.
03:52:38 <CIA-8> 03jepler * 10emc2/scripts/emc.in: Make sure INIFILE is an absoulte path, because the following code assumes it. "that's probably easiest, but it hurts a bit" -- cradek
04:00:18 <CIA-8> 03cradek * 10emc2/scripts/emc.in: unintended consequence when run with no args
04:01:00 <jepler> thanks
04:04:50 <CIA-8> 03jepler * 10emc2/tcl/bin/pickconfig.tcl: give the tree focus, so it's not necessary to tab before using up/down keys
04:09:16 <CIA-8> 03jepler * 10emc2/tcl/bin/pickconfig.tcl: make double click on the tree invoke the OK action

13:37:20 <cncuser> hi folks
13:37:52 <cncuser> does any of you use 2.6.15... kernels ?
13:38:28 <cncuser> i dont quite get the adeos ipipe thingy. the newest patch i aplied didnt have a ADEOS option in it
13:39:26 <cncuser> ... im intend to put together a new puppysit with 2.4.31 & 2.6.15.1
13:40:07 <cncuser> adeos-ipipe-2.6.15-i386-1.2-00.patch
13:40:13 <cncuser> that patch i talk abpout, btw
13:44:22 <cncuser> anyone familiar with the way the adeos-rtai-emc work together ? does emc have to care about ipipe ?
13:51:16 <cncuser> i got http://download.gna.org/adeos/patches/attic/v2.6/i386/adeos-linux-2.6.13-i386-r13.patch its alittle older. it has CONFIG_ADEOS. but has mucho rejects
13:51:19 <cncuser> hmmm
13:54:15 <jepler> I don't know; I wish I did.
13:54:38 <cncuser> jepler: im trying to get the rejects fixed with the above patch. lets see
13:54:40 <cncuser> hi btw ;)
13:54:42 <jepler> hello
13:57:49 <cncuser> jepler: could please again tell me what pythonlibs are needed ? :) i lost oit in some diskimage on some harddisk i dont remember where i put :)
13:58:26 <cncuser> i put it on the wiki. its a safe place i hope
13:59:13 <jepler> cncuser: I had a program that mostly generated the required files .. let me see if I can find that
13:59:42 <cncuser> jepler: yes, you did that nifty tool. and also once told me some links to listings of files
13:59:50 <cncuser> you did with it
14:00:32 <jepler> the lists I found on my website: http://emergent.unpy.net/files/sandbox/python-for-axis.files http://emergent.unpy.net/files/sandbox/python23.zip.txt
14:01:11 <jepler> It looks like the script is there too: http://emergent.unpy.net/files/sandbox/freeze_axis.py
14:01:11 <cncuser> thanks
14:01:20 <jepler> I haven't touched it since that day we talked about it a few months ago
14:02:28 <cncuser> jepler: yes, me neither :)
14:03:28 <cncuser> jepler: i just wanted to build some nice emccdrom and now im going to do a lfs or rocklinuxbased livecddistro with some puppy features.
14:04:50 <cncuser> jepler: is there a way to make axis detect if the gui is metric but the gcode doesnt have the required command in it and just assume it is there ?
14:05:06 <cncuser> or does this break some stuff ?
14:05:32 <jepler> cncuser: It might be possible, but such a feature doesn't exist yet.
14:05:52 <jepler> cncuser: I believe it's a bad gcode file that does not begin with a g20 or g21 code
14:06:49 <cncuser> jepler: ok. then, hmm. if axis is a nice gui, it should tell you about it and maybe give you the option to PREPEND it via the gui ?
14:08:06 <cncuser> axis shows theres something wrong in beautiful graphics :)
14:59:36 <jepler> cncuser: I've committed a change that makes AXIS use the configuration option [EMC]RS274NGC_STARTUP_CODE the same way emc does.  This is now in the latest snapshot, and will be in the eventual 1.2a3 release unless it creates a problem.
14:59:59 <jepler> cncuser: this might help lazy users who don't want to write correct g-code
15:00:07 <jepler> cncuser: right up 'till they send their file to somebody else
15:04:50 <cncuser> jepler: hmm, now i feel bad
15:05:20 <cncuser> jepler: how about a messagebox ? fullscreen, red on black background 42pt letters... ;)
15:06:16 <cncuser> FATAL SYTSEMERROR: YOU NEED TO ADD G20 OR G21 TO YOU G DATA 
15:06:45 <cncuser> SLEFDESTRUCT AVTIVATET
15:07:00 <cncuser> ALL YOU GCODE ARE BELONG TO US
15:07:08 <cncuser> ;)
15:07:49 <jepler> I thought about that, but this is easier to do.
15:08:03 <jepler> and there are probably a lot of things that a true "g-lint" program would check
15:08:25 <jepler> "warning: your tool will probably break on line 333 when you g0 3 inches into the workpiece"
15:09:27 <cncuser> hehe, yes that would be great
15:09:29 <cncuser> :)
15:10:51 <cncuser> id love to make axis know different tools and materials and you just say m-whatever plexiglas or aluminium. that + spindlespeed + power + machinespeed + power should all be calculatet so the user should not have to wporry about breaking tools :)
15:11:29 <cncuser> of course i talk about hobby machinery or minimal rapid prototyping setups, not industrialstyle
15:12:26 <cncuser> .. /scale
15:13:01 <cncuser> what i really miss is a godd camsoftware
15:13:17 <cncuser> i havent managed to get a eps with some curves into a usable gcode file
15:13:43 <cncuser> the beziers get broiken up into a few points and it all look like crap
15:14:48 <cncuser> i can conver6t it to svg... it looks nice in inkscape. but i have no clou on how to continue from here. cam.py doesnt produce usable output.
15:15:10 <cncuser> so i got ps/eps, svg
15:15:25 <jepler> well, there is no gcode for bezier curves
15:15:32 <jepler> so you have to break them up into lines
15:15:43 <cncuser> jepler: hmmm
15:15:53 <cncuser> jepler: arent there circles with gcode ?
15:16:02 <cncuser> os it all points ?
15:16:03 <jepler> there are arcs
15:16:08 <cncuser> arcs cool
15:16:10 <jepler> but beziers are not arcs
15:16:18 <cncuser> ok, but arcs are round right
15:16:33 <cncuser> hmm, lets see if inkscape knows arcs
15:18:17 <cncuser> hmm, ok
15:18:21 <cncuser> it knows it
15:18:22 <cncuser> fine
15:18:38 <cncuser> so all there is with gcode is arcs and lines ?
15:19:00 <cncuser> so if i keep my vectordata on that objects it should easily be gcodeconvertable ?
15:19:48 <jepler> G2 and G3 are the codes for arcs
15:23:07 <jepler> but see http://emergent.unpy.net/index.cgi-files/sandbox/bez.c
15:23:43 <cncuser> harhar
15:23:56 <cncuser> nice if youre into math and or c ;)
15:23:59 <jepler> this program takes a bezier defined by 4 points (two endpoints and two control points) and uses a subdivision algorithm to create a series of lines that are always within 'epsilon' of the true path of the bezier curve
15:24:48 <jepler> perhaps you'd be happier if I re-wrote it in Python for you
15:24:58 <cncuser> jepler: hehe, thanks, not really
15:26:14 <cncuser> jepler: i think i need to rework some basics before this would be usefull. 
15:33:37 <jepler> cncuser: if you're talking about the same 'cam.py' I found in a web search, it looks like 'nverts' (set with commandline option -#) controls how many pieces a bezier is divided into.  Maybe you can try giving a higher number and see if the curves improve.
15:47:33 <cncuser> jepler: i allready use -1000 but dont see any difference..
15:47:43 <cncuser> jepler: but i think its related to my datas

21:23:47 <alex_joni_away> alex_joni_away is now known as alex_joni
21:57:16 <jepler> Many integrated H-bridges have a charge pump and "boot capacitor".  I don't understand why a higher voltage than the drive voltage is required.  Can anyone explain it to me simply?
21:57:54 <alex_joni> DC bridges?
21:57:56 <jepler> I assume that it has something to do with making sure the upper transistors turn off completely, but isn't the drive voltage enough to ensure that?
21:58:10 <jepler> alex_joni: Yeah, for running a bipolar stepper motor
21:59:19 <alex_joni> jepler: depends on the transistur used
21:59:30 <alex_joni> the more expensive way is to use p and N typed
21:59:52 <alex_joni> P for low? and N for high, iirc (it might be the other way around, I tend to mix those)
22:00:14 <alex_joni> but that's more expensive like I said
22:00:42 <alex_joni> so usually only P-type is used (cheaper), but instead you need negative voltages to close it fully
22:01:17 <alex_joni> I don't think the boot capacitor is related to that, more likely to starting a DC motor, which needs higher voltage
22:01:35 <alex_joni> but I might be awfully worng :)
22:13:44 <jepler> I can't accept that you're wrong.  You clearly know more about this than me.
22:14:07 <alex_joni> I should.. 
22:14:16 <alex_joni> but I don't really ;)
22:14:35 <alex_joni> I've read somewhere the Charge cap allows greater PWM speed
22:14:49 <alex_joni> having higher voltage might reduce switchings, so that makes sense

22:46:26 <Jymmm> hola
22:52:49 <dmessier> wanna buy a 14 yr old boy
22:53:14 <cradek> can he run a milling machine?
22:59:46 <dmessier> probably quite welll IF you can get him up and out in the morning
23:00:52 <dmessier> id trade for a 19 yr old girl but the wife seems to think thats NOT right
23:01:34 <bill2or3> better trade her away..
23:02:44 <dmessier> i figure 1 - 38 yr old for 2 19's is a fair trade...
23:02:59 <bill2or3> the math doesn't lie.
23:05:33 <Jymmm> dmessier sounds fair to me

23:08:09 <dmessier> the wife hasnt let me use it... so i guess you can have it
23:08:39 <Jymmm> dmessier: Deal... ship the kid in dry ice
23:09:12 <Jymmm> that should cure his sleeping habbits for about a week.
23:10:18 <dmessier> he eats like a large MULE/ small elk.... be prepared
23:10:40 <Jymmm> oats are cheap
23:11:35 <dmessier> if he's slept for a week you'll need a moderate size heafer for breakfast and 3-4 dozen eggs or the chickens they come from 
23:12:00 <dmessier> he has 2 hallow legs
23:12:08 <dmessier> hollow
23:12:36 <Jymmm> Nah, will put him on an all oat diet + suppliments
23:13:35 <dmessier> he doesnt mind oat meal but he IS a meat eater as his dad is..
23:14:11 <Jymmm> For a treat well toss him some pig ears, snout, and chitlands!
23:14:58 <fenn> kibbles n bits n bits n bits
23:15:07 <dmessier> what part is the chitlands???
23:15:07 <Jymmm> fenn too expensive
23:15:31 <dmessier> pls say it is the nuts?
23:15:56 <Jymmm> close...   intestines of young pigs
23:16:02 <Jymmm> chitlins
23:16:16 <dmessier> cleaned???
23:16:18 <cradek> why is he for sale anyway?  I sense there's a story to be told
23:16:32 <dmessier> like in suasage makin's???

23:18:06 <fenn> buy him "diet for a small planet"
23:18:21 <dmessier> thinks 24 - 7 internet access and the latest pc it his GOD given RIGHT....
