[00:00:03] <jmkasunich> that's nice
[00:00:29] <jmkasunich> my former employer had a vacation year that ended at the end of either May or June, that was nice
[00:00:42] <cradek> ours is our starting anniversary
[00:00:43] <jmkasunich> this employer ends the year in December
[00:01:06] <cradek> seems like it's good to spread them out so everyone doesn't vacation at once
[00:01:14] <jmkasunich> yeah
[00:01:29] <jmkasunich> we just assume nothing will get done the last half of december
[00:01:33] <cradek> I almost (?) have XZ radius comp working
[00:02:11] <cradek> well, for lines, haven't tackled the arcs yet
[00:02:26] <cradek> I wonder if anyone in the history of the world has used inverse time feed move
[00:02:29] <cradek> mode
[00:02:43] <jmkasunich> heh, it causes grief doesn't it
[00:03:02] <cradek> it certainly causes droppings everywhere
[00:03:32] <jmkasunich> I saw some messages on the list about non-trivial kins
[00:03:40] <jmkasunich> that is a complete mess
[00:03:50] <jmkasunich> but I suspect we need to attack it one of these days
[00:04:21] <cradek> I think jepler's Ckins will work fine, it's still orthogonal
[00:04:48] <jmkasunich> the issues are things like homing and jogs and such
[00:04:54] <cradek> yeah
[00:05:01] <cradek> axis doesn't support it at all
[00:05:33] <jmkasunich> very few parts of EMC properly make the distinction between axes and joints
[00:06:10] <jmkasunich> because with trivkins there isn't one, its too easy to gloss over it
[00:06:19] <cradek> yep
[00:07:30] <jmkasunich> one thing at a time tho
[00:09:07] <cradek> yeah radiuses for me right now
[00:09:17] <cradek> next, maybe g76
[00:09:33] <jmkasunich> the radius stuff is mostly in the TP?
[00:09:41] <cradek> no radius comp is all in the interp
[00:10:00] <cradek> moves all get translated into canon calls
[00:10:37] <jmkasunich> cool (I think)
[00:10:54] <jmkasunich> you having fun with INTERP_CODE ?
[00:11:03] <jmkasunich> fun with cpp
[00:11:08] <cradek> it's NOT_TOO_BAD once I'm USED_TO_IT
[00:11:21] <cradek> it's nice that axis shows me what it's doing
[00:11:38] <jmkasunich> yeah
[00:12:03] <jmkasunich> between axis and halscope we've really gained a lot of visibility into formerly invisible stuff
[00:12:23] <cradek> yes, we'd be stuffed without them
[00:33:36] <cradek> what's your next emc project?
[00:37:53] <cradek> can I go back in time and, just in time, shoot whoever is about to run indent on this code?
[00:40:49] <cradek> of course I'd try to talk him out of it first
[00:40:56] <cradek> but failing that...
[01:23:29] <jepler> cradek: how do you feel about requiring python2.4 for axis?
[01:23:41] <jepler> I'm about to write something that uses the 'subprocess' module, which I think is new in 2.4.
[01:26:34] <cradek> that doesn't bother me
[01:26:40] <cradek> what cool thing are you doing?
[01:27:04] <jepler> just trying to improve 'filters'
[01:29:03] <jepler> the AXIS gui just freezes while a filter runs
[01:29:16] <jepler> I want it to re-paint and show somehow that it's waiting..
[02:09:22] <cradek> yay, finally lines work
[20:04:25] <SWPadnos> ok. perhaps lathe code development discussion should go here instead
[20:06:17] <cradek> no kidding
[20:06:20] <SWPadnos> heh
[20:06:44] <SWPadnos> I'm not sure center-of-ball is a good default for lathes
[20:06:48] <cradek> well radius comp uses the center of the "circle" as the control point
[20:06:58] <cradek> for some lathe tools that's appropriate, for others there will be an offset
[20:07:10] <SWPadnos> from what LH wrote, the control point is beyond the cut radius
[20:07:19] <SWPadnos> for lathes, at least
[20:07:32] <cradek> yes for the corner tools, but not for the axis-aligned ones
[20:07:34] <SWPadnos> or was that only for the gouge angles
[20:07:49] <cradek> the point the user specifies is the one in his picture
[20:08:02] <cradek> the one used by radius comp is the center of the tool radius
[20:08:36] <cradek> so there's an offset that you can calculate based on the radius and, uh, angles and stuff
[20:08:42] <SWPadnos> ok. the issue there is that the cutting point is beyond the center of the tool (as used in endmills), but not for what that lathe operators are used to
[20:08:46] <cradek> * cradek waves his hands
[20:09:05] <SWPadnos> right - jommertry
[21:31:47] <alex_jon1> evening
