#emc | Logs for 2009-09-05

[00:02:19] <Jymm> alex_joni: Wel, we dont want it now
[00:07:11] <Jymm> alex_joni: both are dead links fyi
[00:09:03] <Jymm> and it looks like it requires it to call home too
[00:38:10] <renesis> 15:06 < alex_joni> I found a very nice free-ish 2d cad for windows a while ago
[00:38:22] <renesis> free cad == fail
[00:38:43] <renesis> qcad was prob the closest thing to acad functional
[00:44:22] <roh> qcad still works fine for lots of 'small stuff' in 2d
[00:44:55] <roh> we do the cam on it via export to dxf and import in heekscad/cam

[02:31:11] <skunkworks> I don't under stand why all this work is going into something that a servo could do easier and quicker
[02:52:05] <jepler> I don't see the value of point 3 at all
[02:52:13] <jepler> (and emc can put whatever position error you want it to on a servo, no smoke)
[02:53:44] <jepler> I can readily believe that he does find it a rewarding challenge to work on
[02:54:42] <skunkworks> sure
[02:54:58] <skunkworks> I think it is his unicorn
[02:55:22] <jepler> the thing that proves he's a replicant?
[02:56:38] <skunkworks> sorry - I backspaced and the browser went back instead.
[02:57:15] <skunkworks> all sides of the garage are sided. yay
[02:57:28] <skunkworks> je
[02:57:57] <skunkworks> wow - typing without seeing the keyboard can be a pain
[02:58:23] <skunkworks> jepler: did you get your ssr hooked up?
[02:58:38] <jepler> not yet
[03:00:01] <skunkworks> oh well - I think it is time for bed. too much outside work makes me sleepy. (and pizza)
[03:20:36] <jepler> mmm pizza
[17:47:42] <ChanServ> [#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website: http://www.linuxcnc.org/, wiki at http://wiki.linuxcnc.org/"
[17:52:01] <jepler> Jymm: you have to admire the ingenuity, anyway
[17:53:16] <Jymm> jepler: Oh no, I really do, for those that have never touched robotics at all, it's very cool that you can crete something functional in an DIY erector-set.
[17:53:56] <Jymm> Sometimes I've wished that they bring back erector-sets - even w/o the motors and such.
[17:54:44] <Jymm> jepler: I did notice that he has started to see the light with anti-backlash motor couplers too =)
[17:55:38] <Jymm> jepler: I'm not sure what too longer... to fabricate the parts, or to document it all
[18:18:58] <Jymm> jepler: Though, I think he did one hell of a job documenting it all!
[18:26:56] <motioncontrol> good evening.A question about component.if i write setp hm2_5i20.0.pwmgen.00.value 10 ,the analog value up to 0 at 10 volt very fast.exist a componet for create a accelleration and decelleration ramp for analog?
[18:28:36] <jepler> motioncontrol: limit2, limit3
[18:30:12] <motioncontrol> jepler, but the limit not is a componet for control the limit range the a value?
[18:31:05] <alex_joni> man limit3
[18:32:08] <motioncontrol> alex_joni, yes now stay at read the doc. thanks for info
[19:38:21] <klick> ok, where would the default location of the emc log file be? I've never had a need to look till now, and I can't seem to find it anywhere
[19:39:22] <klick> i'm getting ESTOP's without any notification of why, just trying to figure out why
[19:39:58] <klick> nobody out there huh
[19:40:52] <pjm> hello
[19:41:36] <klick> hi
[19:42:40] <micges> klick: can you describe more your issue?
[19:44:19] <klick> well, i start running hte g-code, and all is well, then i'm getting an ESTOP, it has the symptons of a "Joint Following Error", but I don't get the "joint following error", plus I have realtime display of F_ERROR (or whatever it's called), and it goes no where near what my joint following error limit is set to
[19:45:08] <klick> it starts cutting into the piece, and then stops, it hasn't stopped doing freemotion code, so it would make me think of joint following issues, but nothing is showing that, and it just ESTOP's.... i dunno
[19:45:28] <klick> i've cut the same material lots before, using same type of load I always do
[19:45:37] <klick> i decreased the load and it didn't help much
[19:45:38] <skunkworks> klick: one if the most common f_error issues with stepper machines is when you don't have enough stepgen headroom.
[19:46:02] <klick> i've been running the machine for over a year with no issues like this... so i dunno
[19:46:37] <klick> but is there a log somewhere that can show me why it's ESTOP'ing? there has to be some reason
[19:46:54] <klick> or some debug mode i can enter and then show it? cause i can re-produce it everytime
[19:47:11] <micges> you have external estop circuit?
[19:47:31] <klick> i have a few limit switches, but they arne't being pressed
[19:47:58] <klick> well, as far as i know, unless they're shorting out, which is why I was looking for a more details ESTOP reason
[19:48:44] <micges> you can load switches signal to halscope and see if you have some noises
[19:49:11] <klick> ok
[19:49:28] <klick> back to my original question though, wouldn't that be detailed out somewhere in a log?
[19:50:32] <micges> estop and such signals aren't logged becouse it is done in realtime
[19:50:56] <klick> ok, but isn't there some debug mode where i could determine that?
[19:52:25] <pjm> i used to have random estop's - it was caused by noise on the estop line from my VFD, so some shielding etc was done and its fixed completly
[19:52:56] <klick> kinda odd that it would start after a year of using the machine though, isn't it
[19:53:07] <pjm> its strange certainly
[19:53:36] <klick> i am cutting a large chunk of steel, perhaps it's screwing with it, but i cut this same piece tons more before..
[19:53:42] <micges> klick: it's not strange, depend of mounting type of cables
[19:54:01] <klick> my estops are not shielded, they are small wires
[19:54:38] <klick> ok, i'll try halscope i guess, see if i can figure it out
[19:54:56] <klick> i'll have to go down there and login, can't do much from up here
[19:55:01] <klick> thanks
[19:55:16] <micges> if it is noise(and probably is) halscope is the only way to track realtime issues
[19:58:53] <clip9> What would the noise look like? (in halscope)
[20:01:10] <micges> like gliches
[20:01:34] <micges> pinpoints on signal
[20:01:43] <clip9> ah
[20:20:50] <alex_joni> clip9: it would be interesting if you could pastebin the hal file
[20:21:14] <alex_joni> if emc2 goes into ESTOP state, only iocontrol.0.external-estop-request could be set to 0
[20:21:25] <alex_joni> how is ESTOp hooked up on your machine?
[20:21:38] <clip9> eh. better ask klick :P
[20:22:35] <alex_joni> oh, right
[20:22:39] <alex_joni> klick: ^^
[20:22:50] <alex_joni> clip9: too similar nicks :D
[20:22:54] <alex_joni> and it's close to midnight here
[20:23:03] <clip9> hehe
