[00:48:10] <cradek> jepler: that looks very plausible to me
[00:48:19] <cradek> I can't think of a case where those checks are wrong.
[00:48:37] <cradek> i can be negative, but j/k are always positive and they have the relationship you check there
[00:52:02] <jepler> any opinion about the error texts?
[00:52:20] <cradek> they look fine to me
[00:52:26] <jepler> must i be nonzer?
[00:52:27] <jepler> o?
[00:52:44] <jepler> it seems like, physically, it should always be nonzero
[00:52:44] <cradek> hm, yeah I0 makes no sense
[00:52:48] <cradek> right
[00:53:06] <cradek> hmm, I wonder what g76 does in g91 mode
[00:53:13] <cradek> that's a scary thought
[00:53:36] <cradek> I bet it will use find_ends for the Z and therefor honor the g91 for that
[00:55:02] <cradek> yep
[00:55:10] <cradek> ok, it's fine
[00:56:14] <CIA-1> EMC: 03jepler 07master * r5e1a5fb05ca7 10/src/emc/rs274ngc/interp_convert.cc: reject invalid I, J, K values in G76
[00:56:43] <cradek> nifty
[00:58:21] <CIA-1> EMC: 03jepler 07v2_3_branch * r37b4e730bb14 10/ (debian/changelog src/emc/rs274ngc/interp_convert.cc): reject invalid I, J, K values in G76
[01:20:47] <cradek> oops, I think K>J is the wrong test. should it be K>I+J?
[01:21:43] <cradek> err K>fabs(I)+J
[01:22:51] <cradek> sorry, I think I suck at correctly answering "is this right?"
[01:23:32] <jepler> hmph
[01:24:15] <jepler> looking at the drawing marked "thread dimensions" http://linuxcnc.org/docs/html/gcode_main.html#fig:G76-canned-cycle I don't see how it would be K>fabs(I)+J
[01:24:27] <jepler> J and K are both shown as distance from I
[01:24:31] <jepler> is the diagram wrong?
[01:29:45] <cradek> no, I'm wrong
[02:16:50] <jepler> apparently the Freedom of Speech clause in the AK constitution reads: Every person may freely speak, write, and publish on all subjects, being responsible for the abuse of that right.
[02:17:21] <cradek> bizarre
[02:19:55] <jepler> and for some reason, the title of this page currently reads "Lieutenant Governor Sean Parnell" http://ltgov.state.ak.us/constitution.php?section=1
[02:20:54] <jepler> though it did in 2007 as well http://web.archive.org/web/20070609133710/http://ltgov.state.ak.us/constitution.php?section=1 so it's not a recent change
[02:21:16] <jepler> oh, "ltgov"
[02:24:12] <cradek> huh, a right to privacy
[02:24:47] <cradek> wow, and apparently they can only have one marriage in the state at a time (section 25)
[02:31:39] <cradek> it's almost as if they wrote that one in some kind of frenzy and didn't take the time to word it carefully.
[02:38:25] <jepler> 'night
[02:38:41] <SWPadnos> see ya
[06:34:06] <micges> version in topic wasn't changed after 2.3.2
[06:41:04] <alex_joni> alex_joni has changed the topic to: EMC2 development -- http://linuxcnc.org/ | Latest release: EMC 2.3.2 | channel logged by logger_dev
[06:43:49] <micges> cool
[08:52:02] <micges> alex_joni: bug with G76 was fixed yesterday
[08:52:39] <micges> (I think)
[08:55:43] <micges> It will be in 2.3.3
[09:09:09] <alex_joni> micges: feel free to say that on the list if you know ;)
[09:09:13] <alex_joni> http://www.local-guru.net/blog/2009/07/03/arduino-based-office-wtf-counter <- LOL
[09:10:50] <micges> I'm scared ;)
[09:18:28] <alex_joni> ha
[09:20:46] <micges> heh
[10:49:14] <BigJohnT_> BigJohnT_ is now known as BigJohnT
[11:45:32] <CIA-1> EMC: 03jepler 07v2_3_branch * r501df69edec2 10/debian/changelog: note sf bug number
[15:55:36] <CIA-1> EMC: 03jepler 07master * r7eaae3c98c73 10/docs/src/ (5 files in 2 dirs): mini_fr was really a jpeg all along, give it the right filename
[16:23:08] <jepler> the internet suggests to prefer 'git pull --rebase'; this leads to fewer merge commits and makes it easier to revise your work (e.g., with git rebase -i) before pushing.
[19:10:17] <cradek> grrrr
[19:10:57] <mozmck_work> axis: not a joint
[19:13:32] <cradek> yeah, in retrospect...
[21:29:01] <micges> SWPadnos: spindle-at-speed works perfectly, thanks for tip
[21:29:38] <SWPadnos> sure
[21:29:52] <SWPadnos> glad it works for your non-spindle application :)
[21:30:14] <micges> hehe
[21:33:24] <micges> SWPadnos: do you have any experience with integratimg plasma machines?
[21:34:21] <SWPadnos> nope
[21:34:41] <SWPadnos> nut I'll stop in the next time I'm in Poland, if you don't mind me looking over your shoulder :)
[21:35:46] <micges> sure that would be cool
[22:15:59] <micges> good night all
