[12:06:33] <skunkworks> alex_joni: now the irc client scales with screen size. Very nice.
[12:11:54] <alex_joni> really? cool :)
[12:12:06] <alex_joni> I didn't consider that..
[12:12:41] <alex_joni> this is quite nice :D
[12:13:14] <java_client> 'lo :)
[12:13:28] <alex_joni> * alex_joni greets himself
[12:16:26] <skunkworks> heh
[12:24:19] <skunkworks> anyone know german? http://cnc-suite.sourceforge.net/cnc/index.html
[12:32:14] <jepler> alex_joni: I swear that when I removed iocontrol.9 that I added it to section 1!
[12:32:17] <jepler> I didn't?
[12:34:49] <jepler> * jepler scratches his head
[12:36:55] <jepler> alex_joni: in that case, thanks for picking up after me
[12:59:45] <alex_joni> no problem
[12:59:53] <alex_joni> I thought you did too..
[13:00:30] <alex_joni> there was another file called io.9
[13:01:49] <alex_joni> maybe you know what it is..
[13:01:55] <alex_joni> http://cvs.linuxcnc.org/cvs/emc2/docs/man/man9/Attic/io.9?rev=1.1;content-type=text%2Fplain
[13:02:18] <jepler> that makes "man io" show the same page as "man iocontrol"
[13:02:33] <alex_joni> ah, ok
[13:02:50] <alex_joni> then I guess it's needed for (1) too
[13:02:55] <jepler> ".so" is "source"
[13:02:57] <alex_joni> * alex_joni goes away for a while
[13:03:00] <alex_joni> bbl
[13:37:29] <cradek_> cradek_ is now known as cradek
[16:33:31] <Guest356> Guest356 is now known as skunkworks_
[17:13:16] <rayh> cradek: Is the config you used for the NIST lathe around someplace?
[17:13:32] <SWPadnos> configs/nist-lathe ?
[17:13:55] <rayh> duh /me slaps head.
[17:13:58] <SWPadnos> heh
[18:27:22] <alex_joni> hello
[18:32:58] <skunkworks_> Hi alex
[18:33:28] <alex_joni> pretty quiet lately
[18:37:07] <skunkworks_> yah. a bit scary
[18:37:10] <skunkworks_> http://ubuntuforums.org/showthread.php?t=573980
[18:48:00] <alex_joni> hmm.. a user is complaining about a very low feedrate for the following circle:
[18:48:03] <alex_joni> G03 X0 Y0 I0 J-0.0005
[18:48:11] <alex_joni> (it's a very small circle in mm)
[18:48:59] <skunkworks_> is his accelleration set really low?
[18:49:42] <alex_joni> might be
[18:55:00] <fenn> emc has a couple different hard-coded arc tolerance settings. 0.0005 might be below one of them
[18:57:16] <alex_joni> fenn: is hexapod-sim supposed to run?
[18:57:52] <alex_joni> vismach.py: Track: why am i here? world is not in the scene yet
[18:58:54] <alex_joni> http://pastebin.ca/740161
[19:33:46] <cradek> rayh: there's a parport wiring adapter with that lathe too, be sure to not plug in the mighty drive directly to a parport
[19:41:39] <cradek> also there should be a hand-drawn diagram of the wiring
[19:42:20] <cradek> alex_joni: I bet skunkworks_ is right about the accel limit making that arc very slow
[19:43:19] <fenn> alex_joni: it's a bug in the way vismach traverses the tree (?) but doesnt seem to affect anything else
[19:44:02] <fenn> it's dying because of something in the head-up display
[19:44:55] <cradek> max allowed vel of a circle is sqrt(accel limit * radius)
[19:45:17] <fenn> alex_joni: cd emc2/ and cvs up
[19:47:39] <fenn> actually i dont remember committing anything with HUD stuff in hexagui
[19:51:08] <fenn> so i guess "global HUD" doesnt define the variable HUD :(
[19:52:10] <SWPadnos> not in tk
[19:52:21] <SWPadnos> or tcl or whatever it is
[19:52:29] <SWPadnos> dunno about python though
[19:52:42] <fenn> not in python either
[19:52:52] <SWPadnos> oh ;)
[19:53:12] <fenn> i can probably do away with the global now
[19:54:05] <fenn> hmm nope
[20:16:17] <cradek> if the accel limit is 100mm/s2, that gives a feed of .22mm/s, but the circumference of the circle is only .003mm. it should not take long at all.
[20:17:34] <fenn> 0.014 sec
[20:17:50] <cradek> skunkworks_: I think you should post the output of "glxinfo" in that thread. If it shows your system using the mesa software opengl that will be a big clue
[20:18:04] <skunkworks_> ok
[20:18:07] <fenn> * fenn wonders how many thread cycles that is
[20:18:57] <cradek> but nobody should assume my math is right without checking it...
[20:19:22] <fenn> in order to check your math i would have to use an email client of some sort, i suppose
[20:19:33] <cradek> ?
[20:19:54] <skunkworks_> * skunkworks_ wonders why fenn is obsessed with email today
[20:20:50] <fenn> where are you reading about this .0005mm circle?
[20:21:34] <cradek> alex said it above
[20:23:06] <fenn> 100mm/s^2 is pretty high accel
[20:23:15] <fenn> but maybe not for something that does .0005mm circles
[20:32:17] <skunkworks_> http://ubuntuforums.org/showthread.php?p=3552066#post3552066
[22:18:47] <SWPadnos> can you use comp --install to install kernel modules?
[22:18:57] <SWPadnos> ie, new kinematics
[23:09:09] <jepler> SWPadnos: yes that should work
[23:09:28] <jepler> SWPadnos: sudo comp --install for run-installed systems, because regular users can't write to that directory
[23:48:04] <jepler> SWPadnos: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ContributedComponents#How_to_install_a_component
