#emc | Logs for 2006-10-25

[06:40:22] <SWPadnos> I loaded a 2M g-code file into axis, non-remote
[06:40:26] <anonimasu> odd..
[06:40:36] <anonimasu> my axis freezes up for 6minutes when I do it
[06:40:36] <SWPadnos> it took a few seconds (15-20)
[06:40:41] <anonimasu> locally its fast..
[06:40:45] <anonimasu> I wonder if it's a gl issue
[06:40:53] <SWPadnos> but it works on smaller files remotely?
[06:41:02] <anonimasu> no..
[06:41:11] <SWPadnos> so axis doesn't work at all remotely?
[06:41:24] <anonimasu> yes.. but loading stuff takes forever
[06:41:32] <SWPadnos> ok. it may be GL
[06:41:39] <anonimasu> yeah
[06:41:56] <SWPadnos> I'm not sure how GL sends X requests. if there's one (or more) per elment, that could get pretty big
[06:42:26] <anonimasu> wonder what happens if I kill gl
[06:44:26] <anonimasu> glPixelStorei(GL_UNPACK_ALIGNMENT, 1)
[06:44:26] <anonimasu> minigl.error: (1282, 'invalid operation')
[06:44:28] <anonimasu> ah
[06:44:53] <SWPadnos> I guess that's a problem
[06:45:08] <anonimasu> I turned gl on permanenetly now..
[06:45:09] <anonimasu> software
[06:45:44] <SWPadnos> I was pretty amazed at my 7800GT video card with that 2M file
[06:46:06] <SWPadnos> I was able to spin the preview around with zero jitter
[06:46:12] <anonimasu> * anonimasu nods
[06:46:22] <SWPadnos> with axs maximized across both monitors, so 3840x1000 or so
[06:46:26] <anonimasu> hehe
[06:46:26] <SWPadnos> axis
[06:46:28] <anonimasu> cute!
[06:46:37] <SWPadnos> there's a screenshot, but you need a big screen to see it ;)
[06:46:50] <anonimasu> lol
[06:46:55] <anonimasu> my x client stopped doing opengl
[06:47:09] <SWPadnos> http://www.cncgear.com/images/Screenshot.png I think
[06:47:18] <SWPadnos> yep
[06:47:40] <anonimasu> how long time did that take to machine?
[06:47:51] <SWPadnos> I have no idea. I stopped the sim after a while
[06:47:55] <anonimasu> ok
[06:48:15] <SWPadnos> it had something like 500k inches of travel
[06:48:23] <SWPadnos> silly numbers
[06:48:27] <anonimasu> yeah
[06:48:49] <SWPadnos> it's an engraving of a photo, I think. 3 passes at pretty fine resolution
[06:50:25] <SWPadnos> ok. bedtime for me - it's 2:51 AM
[06:50:29] <SWPadnos> see you today :)
[06:50:30] <anonimasu> yeah
[06:50:33] <anonimasu> im going to work now
[06:50:34] <anonimasu> laters
[06:57:50] <alex_joni> night SWPadnos

[09:44:42] <fenn> cnc-drilled solder paste stencils: http://www.pbase.com/eldata/stencils&page=all
[09:44:59] <fenn> seems obvious in retrospect
[09:45:05] <anonimasu> hello
[09:46:06] <fenn> you could use a sheet of something that drills burr-free like phenolic or other thermoset plastic
[09:46:29] <fenn> and avoid having to use a clamp layer
[09:46:44] <anonimasu> Bo^Dick: what's up with that?
[09:51:42] <fenn> from http://groups.google.com/group/comp.robotics.misc/browse_thread/thread/3821e1673e014368
[09:52:38] <anonimasu> yeah
[09:52:50] <anonimasu> but with Bo^Dick's random comment about some allegro based drive..

[10:03:49] <fenn> bad google, bad!
[10:04:19] <fenn> translation of "in kopfe gelangt, was menschen beruehrt"
[10:04:19] <alex_joni> what language was that from?
[10:04:34] <alex_joni> it's not _that_ far off
[11:00:52] <anonimasu> 5lol
[11:06:45] <Bo^Dick> so the architechture of the midband resonance thing wasn't more than a bandpass filter and a timer :|
[12:11:39] <Bo^Dick> the new gecko, appears to involve parts that one would expect for a standard stepper driver, XCR3064 Macrocell (for the logic part), LM339 comparator (current sense pwm), HCF40106 hex schmitt triggers, LMC6034 quad op amp, and four half-bridge gate drivers. where's the magic
[12:13:28] <Bo^Dick> where's the 150 bucks
[12:13:54] <Bo^Dick> it's just sooo standard
[12:15:51] <skunkworks> I think you should post that question on the yahoo gecko group or even here and see what you get http://www.cnczone.com/forums/forumdisplay.php?f=31
[12:24:09] <alex_joni> Bo^Dick: stop doing this
[12:24:21] <alex_joni> it was fun for a while, but it gets cumbersome
[12:24:49] <skunkworks> morning alex
[12:27:02] <alex_joni> hi skunkworks
[12:35:45] <alex_joni> darn.. I really need to pay more attention on TIG welding :)
[12:35:55] <skunkworks> burned your self again?
[12:36:07] <skunkworks> :)
[12:38:42] <alex_joni> yeah.. I keep forgetting not to touch the filler wire after welding :D
[12:39:01] <alex_joni> I have lots of straight lines on my fingers
[13:51:06] <A-L-P-H-A> a-l-p-h-a_EMC, http://pastebin.ca/221015 (3 unit gecko drill pattern)
[13:57:06] <anonimasu> hm
[13:57:17] <anonimasu> A-L-P-H-A: I'll steal that..
[13:57:18] <anonimasu> thanks :)
[13:57:22] <a-l-p-h-a_EMC> np
[13:57:27] <a-l-p-h-a_EMC> I'm testing it right now.
[13:57:30] <a-l-p-h-a_EMC> to see it it works
[13:57:32] <anonimasu> but I need Z movement
[13:57:45] <anonimasu> add Z as a variable :)
[13:57:47] <a-l-p-h-a_EMC> then use
[13:57:50] <anonimasu> drill depth ;)
[13:57:51] <a-l-p-h-a_EMC> g81
[13:57:56] <a-l-p-h-a_EMC> that's the drill thing.
[13:57:57] <anonimasu> drill cycle?
[13:58:04] <anonimasu> how does that work?
[13:58:07] <anonimasu> * anonimasu never used drill cycles
[13:58:09] <a-l-p-h-a_EMC> I still have a quill.
[13:58:18] <a-l-p-h-a_EMC> oh. you HAVE to if you're going to make PCBs with it.
[13:58:28] <a-l-p-h-a_EMC> I'll tell you in a bit.
[13:58:34] <a-l-p-h-a_EMC> going to test this before I head to work.
[13:58:39] <a-l-p-h-a_EMC> <data entry> :(
[13:58:46] <anonimasu> eh?
[13:58:47] <a-l-p-h-a_EMC> 4 years of university... data entry. :'(
[13:59:33] <anonimasu> :(
[14:02:27] <anonimasu> didnt you just finish univ?
[14:04:20] <skunkworks> I think what he is saying is --- I have a 4 year degree but all I am doing with it is data entry.
[14:09:56] <anonimasu> oh, yeah..
[14:10:53] <fenn> hey, you could have spent those four years partying instead
[14:11:01] <anonimasu> yeah
[14:11:02] <fenn> oh damn that was the wrong thing to say
[14:11:11] <SWPadnos> college *is* a party
[14:11:17] <SWPadnos> oops - that was the wrong thing to say
[14:11:21] <anonimasu> ^_^
[14:11:32] <anonimasu> I guess you just gave me a reason to go to a uni
[14:11:37] <anonimasu> just kidding
[14:12:12] <SWPadnos> has anyone else seen the Saturday Night Live skit with Billy Crystal promoting a fake college?
[14:12:48] <SWPadnos> "your parents send us tons of money, we split it, and give you a diploma. If you tell anyone, we will find you and we will kill you"
[14:13:29] <cradek> ha
[14:13:40] <SWPadnos> "you can do whatever you want, and go wherever you want, but you must be on campus for Parent Visitation Day. If you are not present we will find you, and we will kill you"
[14:13:50] <SWPadnos> etc. etc.
[14:13:59] <SWPadnos> that was one of the classics
[14:15:07] <anonimasu> lol
[14:17:47] <SWPadnos> too funny - it's online: http://snltranscripts.jt.org/83/83owinston.phtml
[14:18:51] <anonimasu> how does drill cycles work in emc?
[14:19:06] <SWPadnos> observe the manual, and report back :)
[14:19:23] <a-l-p-h-a_EMC> man... my mill isn't moving where I tell it to.
[14:19:28] <a-l-p-h-a_EMC> moves in that general direction.
[14:19:39] <a-l-p-h-a_EMC> but if I tell it to move 1.75" it moves like 1.6"
[14:19:40] <anonimasu> I were wondering if anyone had tried them
[14:19:56] <a-l-p-h-a_EMC> I thought I fixed this issue.
[14:20:09] <a-l-p-h-a_EMC> 1.5hrs before I go / leave for work.
[14:20:17] <a-l-p-h-a_EMC> MOFO.
[14:21:08] <anonimasu> brb
[14:23:43] <a-l-p-h-a_EMC> 4tpi ball screw. 2:3 (motor, ball screw) gear ratio. gecko g201 (10 uStepping).
[14:23:59] <a-l-p-h-a_EMC> 1.8deg/steppers
[14:24:06] <a-l-p-h-a_EMC> 2000 pulses per rev.
[14:24:31] <SWPadnos> so two turns of the motor give three turns of the screw?
[14:24:57] <a-l-p-h-a_EMC> oops, other way
[14:25:06] <a-l-p-h-a_EMC> 3:2... three turns gives two turns.
[14:25:14] <SWPadnos> ok, so 3:2 ratio, or 1.5x
[14:25:20] <a-l-p-h-a_EMC> 8000 (pulses, per 1" travel) x 1.5 (gear)= 12000 pulses
[14:25:40] <SWPadnos> so 3000 pulses per screw rev * 4 screw revs/inch = 12000 pulses/inch
[14:25:46] <SWPadnos> rigth
[14:25:50] <SWPadnos> right
[14:26:10] <jepler> You have: (1|4 inch/revolution) * (2 revolution / 3 revolution) * (1.8|10 degree / step)
[14:26:13] <a-l-p-h-a_EMC> my input scale is -12000 pulses/inch.
[14:26:13] <jepler> You want: step / inch
[14:26:16] <jepler> reciprocal conversion
[14:26:18] <jepler> * 12000
[14:26:23] <jepler> yep, that's what my calculations say as well
[14:26:40] <SWPadnos> how far does it seem to move?
[14:26:43] <a-l-p-h-a_EMC> why am I short on distance then?
[14:27:06] <a-l-p-h-a_EMC> 'missing' pulses?
[14:27:25] <SWPadnos> when you command a 6" move, how far does it go?
[14:27:29] <jepler> is it the same distance every time? If you run a program that just does 'G0 X0' 'G0 X1' over and over again, does it always return to the same zero?
[14:27:33] <SWPadnos> or a 10" move
[14:28:21] <jepler> have you eliminated backlash? For instance, if you 'G0 X0' 'G0 X1', mark the position, 'G0 X2', does it go 1 inch from X1?
[14:29:21] <a-l-p-h-a_EMC> I did G91G0X6 and it moved 5.625"
[14:29:58] <skunkworks> cradek: do you need me to send this back to you? http://www.electronicsam.com/images/KandT/cncworkshop/thread.JPG
[14:30:33] <a-l-p-h-a_EMC> HA!
[14:30:38] <a-l-p-h-a_EMC> I found out why... I'm so dumb.
[14:30:49] <a-l-p-h-a_EMC> it's a 30tooth to 48tooth gear
[14:31:00] <cradek> skunkworks: no, you'd be surprised how many of those I have already
[14:31:34] <skunkworks> cradek: :) found it in my desk today.
[14:31:39] <SWPadnos> a-l-p-h-a_EMC, dummy
[14:31:42] <SWPadnos> :)
[14:31:58] <a-l-p-h-a_EMC> 8:5 ratio now
[14:32:28] <jepler> 12800 steps per inch?
[14:33:06] <a-l-p-h-a_EMC> yes
[14:33:15] <a-l-p-h-a_EMC> I just realized now... all my backlash shit is bad too.
[14:33:17] <a-l-p-h-a_EMC> doh.
[14:34:21] <a-l-p-h-a_EMC> damn. today's only wednesday?
[14:35:11] <a-l-p-h-a_EMC> argh.

[15:11:05] <anonimasu> radio is shit.
[15:11:18] <alex_joni> anonimasu: nice noise
[15:11:21] <anonimasu> no

[15:34:24] <alex_joni> anyone needs a blackbox? (I know I would love one): http://www.sun.com/emrkt/blackbox/index.jsp
[15:35:17] <jepler> I seem to remember hearing that google was using shipping containers as datacenters
[15:35:43] <jepler> http://www.pbs.org/cringely/pulpit/pulpit20051117.html
[15:35:47] <anonimasu> j,
[15:35:48] <anonimasu> hm
[15:37:01] <jepler> The probable answer lies in one of Google's underground parking garages in Mountain View. There, in a secret area off-limits even to regular GoogleFolk, is a shipping container. But it isn't just any shipping container. This shipping container is a prototype data center. Google hired a pair of very bright industrial designers to figure out how to cram the greatest number of CPUs, the most storage, memory and power support into a 20- or 40-foot bo
[15:38:21] <jepler> A single Project Blackbox could accommodate 250 x64-based servers with 1000 cores. A single Project Blackbox could provide as much as 1.5 petabytes of disk storage or 2 petabytes of energy-efficient tape storage.
[15:38:36] <anonimasu> ^_^
[15:38:55] <jepler> now, granted, cringely was just making s**t up, but apparently he overestimated how much could go in a container
[15:40:23] <anonimasu> hm..
[15:40:25] <anonimasu> how large are they?
[15:40:58] <anonimasu> if you cram a container with 19" servers
[15:41:21] <jepler> a http://www.export911.com/e911/ship/dimen.htm
[15:43:36] <alex_joni> I think I remember them in multiple of 10 feet
[15:43:42] <alex_joni> something like 40 feet the longest
[15:43:54] <alex_joni> jepler: right, thanks
[15:43:59] <jepler> for a "20 foot" container looks like 33m3 and 21600kg
[15:45:01] <alex_joni> I remember them beeing around 4-5000$ / piece ;)
[15:45:08] <alex_joni> had the chance to buy one once :D
[15:50:38] <ejholmgren1> ...
[15:50:42] <ejholmgren1> and you didn't?
[15:51:33] <jepler> what would you do with a shipping container? Besides put a few hundred servers in it, that is...
[16:01:15] <alex_joni> jepler: it was one that had been converted to a weekend getaway home :)
[16:01:27] <alex_joni> s/home/cabin/
[16:01:46] <SWPadnos> that's a fairly popular thing to do in and around LA, I gather
[16:01:55] <SWPadnos> Los Angeles, not Louisiana
[16:02:07] <alex_joni> this was a bit further away than LA though :)
[16:02:16] <alex_joni> although one can easily ship it around :))
[16:02:16] <SWPadnos> you don't have to pay for building permits, so people make offices / shops out of conatainers
[16:02:21] <SWPadnos> heh
[16:02:41] <alex_joni> officer .. I really need to go to the US.. my home is there
[16:02:47] <alex_joni> I sent it last month
[16:02:51] <alex_joni> LOL
[16:03:13] <SWPadnos> ship yourself in it ;)
[16:03:33] <alex_joni> heh.. heard too many container ships sinking lately
[16:03:38] <alex_joni> wouldn't take the chance :P
[16:03:49] <SWPadnos> heh
[16:04:27] <skunkworks> reason why geckos are so well made? mariss knows his shit. http://www.cnczone.com/forums/showpost.php?p=210225&postcount=36
[16:05:24] <SWPadnos> he's only been doing this for 25 years - what does he know?
[16:07:40] <SWPadnos> the nice thing is, he's giving people advice on how to avoid buying his products ;)
[16:07:57] <Lerneaen_Hydra> 'lo
[16:09:02] <skunkworks> SWPadnos: unreal - isn't it. People like that still exist.
[16:09:35] <alex_joni> skunkworks: have an account on groups.yahoo.com ?
[16:11:01] <skunkworks> yes - I think I belong to gecko, cad_cam_dro(sp), Turbocnc ....
[16:11:07] <alex_joni> http://finance.groups.yahoo.com/group/geckodrive/message/9729 <- I thought that's unreal :)
[16:11:21] <alex_joni> talking about "people like that"
[16:12:05] <jepler> too bad I can't read that without signing in
[16:12:13] <jepler> * jepler <-- no patience
[16:13:06] <skunkworks> alex_joni: that is unreal.. Company with concience.
[16:13:31] <SWPadnos> yeah - I wasn't too happy with Mariss' actions on that one. I was very close to sending a message to the list on the subject
[16:13:53] <SWPadnos> I think he was acting like a kid, not a responsible adult
[16:14:01] <SWPadnos> at least it turned out OK
[16:14:29] <alex_joni> jepler: some of the stuff there pays to own an account
[16:14:49] <alex_joni> SWPadnos: he might feel that he has some rights :)
[16:15:15] <SWPadnos> sure, but he should have emailed the company, not post a nasty feedback comment on their website first
[16:16:43] <anonimasu> hm
[16:16:51] <fenn> board artwork is not copyrighted?
[16:16:53] <anonimasu> this toolpath will be fun to watch
[16:17:02] <fenn> thats crazy
[16:19:14] <anonimasu> hehe
[16:19:29] <alex_joni> fenn: I agree..
[16:19:34] <skunkworks> fenn: wasn't it you wanting to do motion control using Rtnet or what ever it is called - real time over ethernet
[16:19:51] <alex_joni> skunkworks: not fenn
[16:20:05] <alex_joni> some guy in .hu, but he walked off the project
[16:20:12] <fenn> i was tossing the idea around a little
[16:20:16] <alex_joni> he got a hal driver for rtnet though before he left
[16:20:33] <fenn> its not really practical for anything small
[16:20:39] <SWPadnos> Eric Johnson did some RTNet stuff
[16:21:14] <SWPadnos> he had a RTNet <-> HAL driver done (but I'm not sure what "done" meant for him)
[16:21:34] <alex_joni> SWPadnos: somehow useable if I recall it ok
[16:21:45] <SWPadnos> yeah, I don't remember exactly what for though
[16:21:54] <anonimasu> now lets see how emc works :)
[16:21:56] <anonimasu> really works :D
[16:21:58] <SWPadnos> I think I asked for a copy, but haven't gotten it (that I can find right now)
[16:22:08] <alex_joni> SWPadnos: it was on the list
[16:22:18] <alex_joni> it basicly did a HAL-HAL bridge over RTNET
[16:22:21] <SWPadnos> actually, it would be cool right now, because I just got my AVR32 development kit :)
[16:23:47] <alex_joni> it was Evert Lammerts
[16:24:06] <alex_joni> not Eric Johnson (Eric did the emcrsh stuff: telnet UI interface)
[16:24:07] <SWPadnos> oops - it was Evert Lammerts :)
[16:24:22] <alex_joni> I got the stuff on the 6th Sept. 2006
[16:24:26] <SWPadnos> ah -right. a .tar.gz file
[16:25:10] <alex_joni> yup, that's the one
[16:25:34] <SWPadnos> maybe I should actually look at it then ;)
[16:27:09] <alex_joni> I just did.. looks nice (the .hal files ar least)
[16:27:13] <SWPadnos> I wonder if I'll be able to use the AVR32 tools (without a DVD drive in my main machine)
[16:31:14] <alex_joni> lol.. this is funny
[16:31:23] <alex_joni> INSMOD="/root/emc2/bin/emc_module_helper insert"
[16:31:28] <alex_joni> _way_ funny
[16:32:31] <cradek> ?
[16:32:49] <alex_joni> thought the purpose of emc_module_helper is not to run as root :)
[16:32:54] <cradek> well true
[16:33:07] <alex_joni> so /root/.. seems funny :)
[16:36:29] <alex_joni> hmm.. the RTnet driver is simpler than I expected
[16:36:39] <Lerneaen_Hydra> hey random question, http://www.clasohlson.se/images/products/S/hi/B/304680_X_2006-06-29_112304_3.jpg <-- how loose is the internal spherical part supposed to be?
[16:37:07] <skunkworks> jeeze - when is source fourge going to add emails to its web interface - oct 1st is the last message on either the deveolper or user side.
[16:37:08] <alex_joni> loose?
[16:37:16] <Lerneaen_Hydra> I've got one where the inner bearing can be rotated (with a small amount of force) without heating the outer holder
[16:38:40] <alex_joni> skunkworks: same for -users
[16:41:21] <fenn> it shouldnt be loose at all
[16:45:22] <alex_joni> logger_aj: search
[16:45:22] <alex_joni> Try this address for searching the logs:
[16:51:28] <CIA-8> 03jepler 07HEAD * 10emc2/src/emc/usr_intf/axis/scripts/axis.py: let - and = jog the selected axis, instead of the nearly-useless zoom in/out
[16:52:52] <skunkworks> fenn: did you see this? http://www.electronicsam.com/images/KandT/servostart/almost.JPG
[17:02:37] <Lerneaen_Hydra> skunkworks: why call it almost?
[17:02:48] <Lerneaen_Hydra> fenn: so they're possibly defective?
[17:11:18] <CIA-8> 03jepler 07HEAD * 10emc2/src/emc/usr_intf/axis/scripts/axis.py: which way do you want to jog today? How about: BOTH WAYS
[18:04:36] <ejholmgren1> is any bearing with an ABEC rating an angular contact bearing?
[18:05:59] <Lerneaen_Hydra> afaik they're mostly standard single-row deep-groove radial bearings
[18:34:27] <ejholmgren1> if I use a pair of ABEC 5 or 7 on either end of my leadscrews
[18:34:47] <ejholmgren1> will it work good enough for hobby use?
[18:35:42] <ejholmgren1> provided that I'm not slamming them with 1000oz steppers and a 100lb gantry
[18:37:05] <SWPadnos> consider that inline skates (rollerblades) often use ABEC 7 bearings, and that's for a 175-lb person on 4 wheels (or thereabouts) per foot
[18:37:42] <Lerneaen_Hydra> ejholmgren1: you'll need to preload them, but otherwise it should work quite well if the strength is good enough
[18:37:46] <anonimasu> * anonimasu sighs
[18:37:48] <Lerneaen_Hydra> IIRC they're 8mm ID
[18:37:52] <anonimasu> I just fucked up a part :/
[18:37:55] <Lerneaen_Hydra> * Lerneaen_Hydra pokes anonimasu
[18:37:56] <anonimasu> arther my machine did
[18:38:05] <anonimasu> damn.
[18:38:19] <anonimasu> my drives got too hot and the g340's died.
[18:38:21] <Lerneaen_Hydra> not so fun
[18:38:24] <Lerneaen_Hydra> :|
[18:38:30] <Lerneaen_Hydra> *not* so fun
[18:38:32] <anonimasu> want a pic of the part?
[18:38:33] <anonimasu> ^_^
[18:38:36] <Lerneaen_Hydra> haha, sure
[18:39:00] <SWPadnos> maybe it's time to hook up the GSI ;)
[18:39:10] <anonimasu> lol
[18:39:48] <anonimasu> I'll get a screenshot in a bit and post it once I get to the place where i'm going
[18:39:53] <anonimasu> need to go outside to do it
[18:39:54] <anonimasu> :)
[18:39:58] <anonimasu> bbiab..
[18:40:05] <SWPadnos> too much smoke for indoors? :)
[18:40:08] <anonimasu> SWPadnos: yeah or machine another heatsink so I can add a fan
[18:40:25] <SWPadnos> get a P3 or P4 fan, that's the size the geckos are made for
[18:40:40] <anonimasu> hm, I have a large slab of alu with fins
[18:40:41] <anonimasu> )
[18:40:43] <anonimasu> :)
[18:40:48] <anonimasu> and a 220v fan..
[18:40:55] <anonimasu> that'll go on the controller box..
[18:40:57] <SWPadnos> that should suffice
[18:40:59] <anonimasu> yeah
[18:41:12] <anonimasu> I used to cool my computer with one when we were overclocking.. several years ago
[18:41:20] <anonimasu> also cooled cola with it..
[18:41:20] <anonimasu> :D
[18:41:29] <anonimasu> and managed to get a finger in there once..
[18:41:40] <anonimasu> it split my nail..
[18:41:48] <SWPadnos> ouch
[18:42:05] <anonimasu> well anyways brb..
[18:43:48] <Lerneaen_Hydra> I did something similar before, on a 70mm plastic fan, it actually cut into my finger and drew blood, amazingly (a tiny little 70mm fan...)
[18:44:28] <SWPadnos> higher speed, so higher inertia (maybe?)
[18:44:55] <Lerneaen_Hydra> hmm mv^2/2 and all
[18:45:14] <Lerneaen_Hydra> still, it was unexpected to say the least
[18:45:17] <SWPadnos> the little ones go faster - I think it's an insecurity thing :)
[18:45:31] <skunkworks> I have probably taken the blades off of about 20 computer fans with my fingers. Blindly feeling heat sink temp. Kinda stings.
[18:46:05] <skunkworks> ok - maybe 10
[18:46:09] <Lerneaen_Hydra> heh, nice
[18:46:10] <SWPadnos> liar!
[18:46:37] <skunkworks> they sure do vibrate when they are not balanced anymore ;)
[18:46:58] <SWPadnos> annoyingly loud, for sure
[18:47:20] <SWPadnos> the loudest fans in any computer I have are the wobbly little 40mm chipset fans
[18:47:57] <Lerneaen_Hydra> you've still got them there?
[18:48:08] <Lerneaen_Hydra> why not remove and switch for some random heatsink?
[18:48:24] <SWPadnos> I replaced a couple, which helped
[18:48:33] <Lerneaen_Hydra> oh
[18:48:38] <SWPadnos> actually, on my big machine the chipset fan is a little quieter than the video card fan
[18:48:54] <SWPadnos> the chipset fan is needed on that motherboard
[18:49:24] <Lerneaen_Hydra> I dislike all fans under 60mm or so, as they do little to no good and make tons of noise and have a lousy lifespan
[18:49:49] <anonimasu> now
[18:49:51] <anonimasu> :D
[18:50:03] <Lerneaen_Hydra> anonimasu: got an image?
[18:50:36] <anonimasu> http://aÃlmaskin.se/screenshot.png
[18:50:38] <anonimasu> in 3 seconds
[18:51:00] <SWPadnos> err - does that work? (a URL with extended chars in it)
[18:51:14] <anonimasu> now
[18:51:16] <Lerneaen_Hydra> depending on encoding
[18:51:22] <Lerneaen_Hydra> it sort-of does
[18:51:28] <anonimasu> http://almaskin.se/screenshot.png
[18:51:29] <Lerneaen_Hydra> anonimasu: is that an ä?
[18:51:43] <anonimasu> A
[18:51:44] <anonimasu> :D
[18:51:46] <ejholmgren1> SWP: was actually planning on using 1/2" ID skate bearings
[18:51:48] <Lerneaen_Hydra> oh, that works
[18:52:00] <Lerneaen_Hydra> what's the part going to be?
[18:52:03] <anonimasu> I were on the final passes of that..
[18:52:10] <anonimasu> itÃ's a switch mount for a customer
[18:52:13] <SWPadnos> a switch knob
[18:52:32] <anonimasu> there's a hole at top where a microswitch goes..
[18:52:34] <Lerneaen_Hydra> oh, so it's quite small (10-20mm)?
[18:52:38] <anonimasu> yeah
[18:52:39] <skunkworks> anonimasu: how are you liking emc2 + axis so far?
[18:52:43] <Lerneaen_Hydra> ok
[18:52:45] <anonimasu> the switch is 12.5mm
[18:52:46] <SWPadnos> 25.6 x 53 or so ;)
[18:52:50] <anonimasu> 12 actually..
[18:53:08] <anonimasu> skunkworks: it rocks
[18:53:12] <skunkworks> :)
[18:53:16] <anonimasu> I need a new encoder so I get a servo at Z tomorrow..
[18:53:27] <anonimasu> the stepper dosent move more then 100mm/min :/
[18:53:55] <Lerneaen_Hydra> eek
[18:53:56] <Lerneaen_Hydra> slow
[18:53:59] <anonimasu> yeah
[18:54:08] <Lerneaen_Hydra> 100 sounds really slow though
[18:54:11] <anonimasu> I want 5m/min
[18:54:14] <anonimasu> it's awfully slow
[18:54:16] <Lerneaen_Hydra> tons of steps/rev?
[18:54:21] <anonimasu> yeah
[18:54:26] <anonimasu> 300 I think
[18:54:26] <Lerneaen_Hydra> my 72step/rev do 700mm/min
[18:54:43] <anonimasu> the trouble isnt the step ammount
[18:54:46] <anonimasu> I've got a usc..
[18:54:51] <SWPadnos> he's got a USC, so he can output >1 M steps/sec
[18:55:02] <anonimasu> the trouble is the motor..
[18:55:05] <anonimasu> it goes "whirr"
[18:55:07] <anonimasu> when I try to run it faster
[18:55:12] <alex_joni> stalls?
[18:55:15] <anonimasu> yeah
[18:55:23] <anonimasu> it's not eating lots of current either..
[18:55:25] <alex_joni> too much accel
[18:55:29] <anonimasu> nah
[18:55:33] <SWPadnos> does it do that even when disconnected from the machine?
[18:55:36] <alex_joni> what are you driving it with ?
[18:55:59] <anonimasu> g210
[18:56:07] <alex_joni> anonimasu: proper resistor on it?
[18:56:11] <Lerneaen_Hydra> probably it's got a resonant freq there
[18:56:17] <anonimasu> no resistor..
[18:56:23] <alex_joni> anonimasu: ??
[18:56:23] <SWPadnos> the geckos are immune to mid-band resonance
[18:56:32] <SWPadnos> no resistor = 0 current limit
[18:56:37] <anonimasu> yeah..
[18:56:44] <anonimasu> that's the point of not having one..
[18:56:45] <SWPadnos> ie, limited to minimum, not "no limit"
[18:56:45] <alex_joni> really?
[18:56:51] <anonimasu> wtf?
[18:56:54] <anonimasu> LOL!
[18:57:00] <anonimasu> thanks swp :D
[18:57:07] <SWPadnos> R=47000*I / (7-I)
[18:57:11] <anonimasu> _if_ you were a girl I'd hug you.
[18:57:21] <SWPadnos> heh
[18:57:24] <SWPadnos> no thanks :)
[18:57:29] <alex_joni> he looks like one.. doesn't that count?
[18:57:33] <anonimasu> no
[18:57:35] <alex_joni> * alex_joni hides
[18:57:49] <SWPadnos> I look like "a homely woman", according to my best friend's mother ;)
[18:57:55] <anonimasu> haha
[18:58:04] <anonimasu> well I think I'll be able to run them a bit faster..
[18:58:05] <alex_joni> the huggable type
[18:58:05] <anonimasu> :D
[18:58:10] <Lerneaen_Hydra> that resistor, is that somthing gecko-related?
[18:58:15] <anonimasu> yeah
[18:58:20] <Lerneaen_Hydra> ok, good
[18:58:23] <SWPadnos> hmmm - I may be wrong about that, so I wouldn't necessarily get the hug anyway
[18:58:37] <anonimasu> lÃet me see at the top
[18:58:53] <Lerneaen_Hydra> * Lerneaen_Hydra sprays anon with some rainbow spray
[18:59:00] <anonimasu> vchm
[18:59:00] <SWPadnos> since 7A would be infinite resistance (divide-by-0)
[18:59:09] <Lerneaen_Hydra> anon: your characters are messed up
[18:59:12] <anonimasu> OPEN = 7A
[18:59:30] <SWPadnos> but it does seem like a current limit (or lack of torque) problem
[18:59:44] <SWPadnos> you should try disconnecting it from the machine and see if it still happens
[18:59:55] <anonimasu> hm, I'll do that
[19:23:12] <Lerneaen_Hydra> anyone know of a good OSS math app?
[19:23:27] <cradek> what kind of math?
[19:24:23] <Lerneaen_Hydra> stuff that's too large/complex for the default calculators
[19:24:31] <Lerneaen_Hydra> like complex numbers, matrices and so on
[19:25:01] <alex_joni> there was one mentioned on the emc lists recently
[19:25:19] <Lerneaen_Hydra> mail lists?
[19:26:02] <jepler> I've heard of this but never used it: http://www.gnu.org/software/octave/
[19:26:15] <jepler> you may find other useful software here : http://freshmeat.net/browse/98/
[19:27:09] <cradek> as an everyday calculator I like orpie, which has basic support for complex numbers and matrices
[19:27:28] <SWPadnos> I think Octave is basically equivalent to Matlab - it's not quite a calculator ;)
[19:27:44] <cradek> yeah I'm not sure still what you're looking for
[19:27:46] <jepler> cradek: you're a big rpn bigot, I remember now
[19:27:49] <alex_joni> yeah, octave it was
[19:28:07] <SWPadnos> I like this, from the Octave FAQ:
[19:28:10] <cradek> yeah I prefer an rpn calculator
[19:28:14] <SWPadnos> "I wrote some code for MATLAB, and I want to get it running under Octave. Is there anything I should watch out for?"
[19:28:16] <SWPadnos> The differences between Octave and MATLAB typically fall into one of three categories:
[19:28:17] <SWPadnos> 1. Irrelevant.
[19:28:19] <SWPadnos> 2. Known differences, perhaps configurable with a user preference variable.
[19:28:20] <SWPadnos> 3. Unknown differences.
[19:28:32] <alex_joni> lol
[19:28:33] <SWPadnos> RPN is teh bomb!
[19:28:34] <cradek> haha
[19:28:54] <SWPadnos> I still use my HP 28C and 28S daily
[19:29:07] <cradek> I'm baffled by non-RPN calculators :-)
[19:29:09] <Jymmm> JP20s
[19:29:13] <Jymmm> HP20s
[19:29:27] <Lerneaen_Hydra> I'm trying to find something that's semi-easy to use (gui is good) and is similar to the "standard" calc but more powerful. (for the days when I don't want to do cramers rule for a 3x4 matrix by hand. :/ )
[19:29:41] <cradek> that would be most days I'm sure
[19:29:47] <skunkworks> my programmer can't do anything unless his calculator has rpn
[19:30:01] <alex_joni> no, he has days when he really feels the urge to do it by hand
[19:30:02] <skunkworks> I on the other hand like my calculator to act the same as my computer.
[19:30:19] <Lerneaen_Hydra> skunkworks: you make it seem like you own a programmer
[19:30:26] <alex_joni> Lerneaen_Hydra: ebay
[19:30:27] <Lerneaen_Hydra> then again that's nearly how it is nowadays
[19:30:28] <SWPadnos> I have a PIC programmer
[19:30:34] <Lerneaen_Hydra> code monkey comes to mind
[19:30:44] <Lerneaen_Hydra> (the song)
[19:30:47] <skunkworks> I should say - The programmer I supervise... :)
[19:30:48] <SWPadnos> and AVR, and 68HC..., and FPGA, and ...
[19:31:03] <alex_joni> SWPadnos: small and chinese?
[19:31:06] <SWPadnos> "It's All About The Pentiums, Baby"
[19:31:27] <SWPadnos> yeah, with a microscope for changing fuses ;)
[19:31:59] <alex_joni> nice
[19:35:13] <cradek> Lerneaen_Hydra: [[5, 10]] RET [[10, 0][0, 1]] / => [[0.5, 10]]
[19:35:36] <cradek> and if you cursor up into the stack and hit E for edit, you get vi :-)
[19:35:39] <cradek> what more can you want?
[19:35:42] <Lerneaen_Hydra> I don't get that syntax
[19:35:52] <alex_joni> cradek: maybe if it works out of axis...
[19:35:54] <Lerneaen_Hydra> * Lerneaen_Hydra has never done rpm
[19:35:56] <Lerneaen_Hydra> *rpn
[19:36:20] <cradek> oh...
[19:36:24] <cradek> keep looking then :-)
[19:36:42] <Lerneaen_Hydra> what is the operation done?
[19:36:51] <cradek> divide
[19:37:08] <Lerneaen_Hydra> and what is the input?
[19:37:13] <Lerneaen_Hydra> a series of numbers? matrices?
[19:37:23] <cradek> solving Ax=B where A and B are matrices
[19:37:28] <skunkworks> When I first learned about rpn - I thought it was a joke. seriously. ;)
[19:37:45] <cradek> so you enter B, then A, then divide
[19:37:46] <skunkworks> racial joke that is :)
[19:38:40] <Lerneaen_Hydra> Ax=B? which type of operation is that?
[19:39:09] <alex_joni> that's not an operation..
[19:39:24] <Lerneaen_Hydra> ssh
[19:39:32] <cradek> solving for the unknowns just like when you use kramer's rule
[19:39:51] <cradek> I solved the system of two equations in two unknowns
[19:40:36] <Lerneaen_Hydra> oh! so the systems are 10a+0b=5 and 0a+b=10?
[19:40:43] <Lerneaen_Hydra> and then cramers rule?
[19:40:49] <cradek> yes
[19:41:19] <cradek> it's just the basic way to solve a system using a calculator that does matrices
[19:41:31] <Lerneaen_Hydra> right, ok. it's kind of hard to figure out that by just looking at the numbers :P
[19:41:40] <cradek> yeah, sorry
[19:42:06] <cradek> I thought it was "obvious" because of all the zeroes, I just wanted to show that orpie can do this thing you want
[19:42:06] <Lerneaen_Hydra> the calc's that I've tested on have a very different form of solving that (ti-83 if that says anything)
[19:42:24] <cradek> how do you do it?
[19:43:46] <Lerneaen_Hydra> it has a mode where you enter the matrix in a rather graphical manner (it makes a grid with the correct number of rows/columns) then you just choose <function-name-that-I've-forgot-and-is-nonintuive>(matrix<number>)
[19:44:51] <Lerneaen_Hydra> http://images.google.com/imgres?imgurl=http://www.wisfaq.nl/bestanden/q17901img1.gif&imgrefurl=http://www.wisfaq.nl/showrecord3.asp%3Fid%3D17901&h=128&w=192&sz=2&hl=en&sig2=xHErS3SCkBuLfEp_3yHQpw&start=14&tbnid=GsE3CsC2CBfmaM:&tbnh=69&tbnw=103&ei=4r4_RYX0ILXmwQGR_42xBQ&prev=/images%3Fq%3Dti83%2Bmatrix%26svnum%3D10%26hl%3Den%26lr%3D%26sa%3DG
[19:44:55] <Lerneaen_Hydra> a bit like that
[19:44:55] <cradek> the hp-48 will show the matrix in a square, which is nice, but making you use arrows and stuff to enter it just makes it tedious I think
[19:45:07] <Lerneaen_Hydra> yeah it's a bit slow
[19:45:31] <cradek> oh ick
[19:46:35] <cradek> that looks pretty painful
[19:46:40] <Lerneaen_Hydra> http://qalculate.sourceforge.net/features.html <-- looks promising when it's done
[19:46:53] <Lerneaen_Hydra> yeah, it's quite slow if you've got large stuff or do it often
[19:47:09] <Lerneaen_Hydra> still, better than by hand (which is what I'm stuck with ATM)
[19:47:22] <cradek> sure
[19:47:36] <cradek> kramer's is simple for a machine but very easy to mess up
[19:48:28] <Lerneaen_Hydra> yeah. a pita too... (3x3 is not fun)
[19:48:55] <cradek> it should not be hard to find a program that helps with that
[19:49:37] <anonimasu> * anonimasu ponders how much more torque he needs for moving Z
[19:50:52] <CIA-8> 03jepler 07HEAD * 10emc2/docs/src/motion/kinematics.lyx: technicalities of a kinematics module
[19:51:20] <Lerneaen_Hydra> for stuff like that I found a thingy on the net that did that
[19:52:10] <anonimasu> calculating?
[19:52:13] <anonimasu> motioneering does..
[19:52:19] <anonimasu> though I have no idea how much it does weigh
[19:52:55] <Lerneaen_Hydra> * Lerneaen_Hydra is going to test qalculate
[19:55:21] <Lerneaen_Hydra> hey it looks quite nice actually
[19:55:49] <SWPadnos> I'm assuming you have different font and color choices than the person who posted the screenshots...
[19:55:56] <Lerneaen_Hydra> definetly
[19:56:09] <Lerneaen_Hydra> it uses gtk it seems
[19:56:20] <Lerneaen_Hydra> at least the icons remind me of it
[19:56:31] <SWPadnos> KDE or GTK, according to the docs
[20:00:33] <anonimasu> :)
[20:08:14] <Lerneaen_Hydra> that seems to be a good app for simple math stuff
[20:08:33] <Lerneaen_Hydra> (by simple I mean stuff that you don't do in matlab/mathcad/maxima etc)
[20:08:50] <Lerneaen_Hydra> ie where you can remember where in your calculations you are at all times
[20:12:05] <Lerneaen_Hydra> bah. 'night people
[20:12:15] <alex_joni> bah
[20:12:28] <Lerneaen_Hydra> nya nya nya
[20:12:31] <Lerneaen_Hydra> * Lerneaen_Hydra pokes alex
[20:15:35] <skunkworks> on a side note - we had spent half a day doing a equation subsitution for our costing software trying to figure out a markup issue. anyways - it calcualted out to a constant. Blew us away. kept thinking "this can't be right" - but it was.
[20:16:31] <SWPadnos> Price = 327 x cost. Simple, really.
[20:16:48] <anonimasu> hehe
[20:17:28] <skunkworks> that is pretty clost to what the solution was. eveything started canceling out - until we ended up with .0505 or something like that. It was quite funny.
[20:17:47] <SWPadnos> I had the same thing happen in my high school physics class
[20:18:08] <SWPadnos> the experiment where you roll a ball down an incline, and try to get it to go into a cup
[20:18:46] <SWPadnos> I twiddled with the equation, until I found that the angle of the incline made no difference, it was dependent only on the height from which the ball was released
[20:19:50] <SWPadnos> everyone else was agonizing on cosines and stuff. when I mentioned my discovery, the teacher heard me and conspiratorially said "shhh - don't tell them that"
[20:19:52] <skunkworks> exactly
[20:22:36] <jepler> I hate teachers
[20:27:43] <skunkworks> hate is a strong word.. ;)
[20:34:38] <alex_joni> jepler: I used to feel pretty similar
[20:34:45] <alex_joni> till I started teaching people things
[20:34:54] <alex_joni> and found out it's quite a hard thing to do
[20:42:21] <skunkworks> jepler: could you explain this on your servo etch-o-sketch? looks like your using pwm+dir
[20:42:25] <skunkworks> linksp Xdir => parport.0.pin-02-out
[20:42:52] <alex_joni> skunkworks: thought you know what an linksp does
[20:43:06] <skunkworks> sorry it didn't paste rigth
[20:43:25] <alex_joni> :P
[20:43:31] <skunkworks> he is linking xdir to 2 parport pins. and xpwm to one.
[20:44:00] <jepler> skunkworks: L298 has A, B and ENABLE pins for each bridge.
[20:44:11] <jepler> the pin I toggle is ENABLE
[20:44:26] <jepler> so A gets DIR, B gets !DIR, and ENABLE gets pwm'd
[20:44:44] <jepler> this uses an additional I/O per bridge, but means the time PWM is off is coasting, not braking
[20:45:24] <skunkworks> ah - elegant. Thanks
[20:47:02] <skunkworks> jepler: why did you want it to coast?
[20:47:42] <skunkworks> easier to manually move during estop?
[20:49:39] <SWPadnos> if you don't do that, then the off time tries to drive against the on time of the PWM
[20:49:50] <SWPadnos> ie, it's push-pull instead of push-wait
[20:59:23] <skunkworks> This would be great if I had a cubicle http://www.youtube.com/watch?v=izyFg0xCg7Y&mode=related&search=
[20:59:28] <mtedad> Q have added 32 lines of commented out # text to io.hal in configs, emc2 won't come up. any ideas fellas.
[20:59:36] <CIA-8> 03alex_joni 07HEAD * 10emc2/docs/src/motion/pid_theory.lyx: added pid description
[20:59:53] <alex_joni> mtedad: the # commented code doesn't influence it
[21:00:03] <alex_joni> unless you commented something out by mistake
[21:00:12] <alex_joni> mtedad: what's the error you're seeing?
[21:00:43] <mtedad> where do i find an error?
[21:01:10] <alex_joni> mtedad: run a terminal (applications-> accessories -> terminal)
[21:01:15] <alex_joni> and issue "emc"
[21:01:34] <mtedad> ok
[21:01:35] <alex_joni> it will work just like from the menu, but error messages will get printed in the terminal you started
[21:05:30] <mtedad> Hal 97 error,bad varible replacement. then io.hal failed
[21:05:51] <alex_joni> ok, probably it's looking for a variable in the ini which doesn't exist anymore
[21:06:16] <alex_joni> can you put the io.hal file and the .ini file at http://pastebin.ca/ ?
[21:06:18] <SWPadnos> either that or there's a misspelled variable name or section name in the .hal file
[21:12:09] <mtedad> i pasted in the block from another file it was completely #out
[21:12:37] <alex_joni> mtedad: check if the comments have parts that look like [foo]bar
[21:12:54] <alex_joni> if that's the case, please delete the []'s
[21:13:57] <mtedad> could not find an typo or [foo}bar, but cut out block and it loaded.
[21:14:30] <SWPadnos> can you paste it to http://pastebin.ca (the one that doesn't load)?
[21:14:41] <CIA-8> 03alex_joni 07HEAD * 10emc2/docs/src/ (Master_Integrator.lyx index.tmpl): added PID description
[21:17:45] <alex_joni> mtedad: especially line 97
[21:17:47] <mtedad> machine not connected to internet.
[21:18:36] <SWPadnos> can you copy the io.hal file to a floppy or USB stick and paste it from the machine you're on?
[21:19:27] <alex_joni> mtedad: I didn't mean literally foo and bar (those are just expressions)
[21:19:37] <alex_joni> but if it loads now, then you should be set :)
[21:23:28] <anonimasu> ;)
[21:23:45] <CIA-8> 03jepler 07HEAD * 10emc2/src/hal/utils/halcmd.c:
[21:23:45] <CIA-8> BACKPORT CANDIDATE: bogus error about inifile subsitution and possible segfault:
[21:23:45] <CIA-8> $ echo '# [A]Q' | halcmd -i /dev/null -f
[21:25:10] <skunkworks> LawrenceG: you where talking to me yesterday?
[21:25:44] <LawrenceG> yea... saw you called me... how is the servo drive project running?
[21:26:26] <skunkworks> Waiting on encoders to play. So far so good. Did you see my halscope of a mouse encoder?
[21:27:51] <LawrenceG> yes... looks nice... Ted (tfmacz) has several Toyota heater fan motors with mouse wheels mounted on the back running as servos
[21:28:38] <skunkworks> That is so neat.
[21:28:46] <skunkworks> how do they perform?
[21:29:09] <LawrenceG> resolution is OK as long as one is using a large motor to drive reduction like 5/16x18 or 1/4x20 threaded rod
[21:29:27] <skunkworks> is cogging and issue?
[21:30:19] <LawrenceG> They are strong little motors.... I have several "racing stripes" across my fingers from trying to stall them by grabbing the pulleys
[21:30:45] <skunkworks> I took the guts from a mouse and transfered them to a single channel encoder to make it quaditure. Need a little tweeking - but so far so good.
[21:32:02] <CIA-8> 03alex_joni 07HEAD * 10emc2/docs/src/ (Submakefile index.tmpl): we want to build html docs for pid_theory too
[21:32:22] <LawrenceG> cogging doesnt seem to be an issue... Ted and I am using the servo driver I designed http://members.shaw.ca/swstuff/dspic-servo.html kind of a home brew gecho with less voltage/current output
[21:34:01] <skunkworks> Got to run - bbl
[21:34:07] <LawrenceG> cheers
[21:37:43] <alex_joni> * alex_joni leaves for a while
[21:37:44] <alex_joni> bbl
[21:41:48] <mtedad> tried pasting to pastebin,how do isend it?
[21:42:20] <SWPadnos> you clicked on "submit post"
[21:42:22] <SWPadnos> ?
[21:42:34] <mtedad> did that.
[21:42:35] <SWPadnos> if so, then just paste in the URL it gave you for the file
[21:42:47] <SWPadnos> nevermind - I see it
[21:42:52] <SWPadnos> http://pastebin.ca/221790
[21:43:09] <SWPadnos> one of your # signs is a $ sign
[21:43:11] <SWPadnos> on line 97
[21:43:42] <SWPadnos> $ means "use an environment variable", which is why you get the error you're getting
[21:44:24] <mtedad> got it. blind as a bat ain,t i
[21:44:26] <SWPadnos> (you have no environment variable named "linksp" :)
[21:44:28] <SWPadnos> heh
[21:44:33] <SWPadnos> happens to everyone
[21:44:45] <mtedad> thanx
[21:44:49] <SWPadnos> sure
[21:45:13] <SWPadnos> note that the error actually did point you right at the problem (that doesn't always happen, but it's a good place to start :) )
[21:45:45] <anonimasu> bbl
[22:07:51] <CIA-8> 03jepler 07HEAD * 10emc2/src/Makefile: it is useful to search the share/axis/tcl directory, so index it with tags and swish
[22:11:15] <CIA-8> 03alex_joni 07HEAD * 10emc2/docs/src/motion/pid_theory.lyx: use some more relevant names
[22:26:49] <alex_joni> good night all
[22:28:35] <skunkworks> night alex
[22:41:51] <anonimasu> adhm
[22:41:59] <anonimasu> another heatsink machines..
[22:42:04] <anonimasu> machined
[22:43:24] <anonimasu> ^_^
[22:44:20] <mtedad> Q fellas need the halcmd to turn on motenc.0.out-00 ON
[22:50:03] <jepler> in emc 2.0.x, the way to set a PIN to a particular value is this: create a signal of the appropriate type. use "setp" to give it a value. "link" it to the pin.
[22:50:33] <jepler> so assuming motenc.0.out-00 is a bit, it would be something like this (but split across 3 lines): newsig TRUE bit; setp TRUE 1; linksp TRUE => motenc.0.out-00
[22:52:15] <anonimasu> jepler: do you have experience with geckos?
[22:52:40] <jepler> anonimasu: no
[22:52:47] <anonimasu> ok.. that's too bad..
[22:55:10] <anonimasu> * anonimasu yawns
[23:16:35] <mtedad> thanx again tried setp a number of ways but didn't link it.
[23:17:19] <cradek> ?
[23:22:35] <SWPadnos> wow - memtest takes a long time for 4G
[23:22:52] <cradek> yep
[23:23:24] <SWPadnos> I finally put the new CPUs in the Opteron machine - I'm curious as to how much faster (and how much more power) they'll be
