[02:56:55] <mozmck> Are string values in the INI case sensitive?
[02:58:22] <mozmck> I see LINEAR_UNITS = inch, and TYPE = LINEAR
[02:58:38] <mozmck> can inch be INCH and LINEAR be linear?
[03:12:40] -!- Valen has quit [Remote host closed the connection]
[03:15:06] <kwallace> I think it depends on the code that checks a particular parameter. I seem to recall seeing "if 'inch' or 'INCH' then blah". Which I suppose doesn't cover "Inch". I would tend to grep the source for the parameter name to find the affecting code.
[03:15:23] <mozmck> yuck
[03:15:36] <mozmck> but thanks. I'll do some grepping

[03:59:33] <seb_kuzminsky> mozmck: our IniFile library (in src/libnml/inifile) is case *sensitive*, so if you ask for "inch" it will *not* find "INCH" for you
[04:01:20] <mozmck> ok, thanks. I just took the lazy way and made my program use values I know work.
[04:01:35] <mozmck> Instead of digging through that stuff right now
[04:04:15] <seb_kuzminsky> i guess that's why all our ini files and ini file accesses use upper case, it's as good a standard as any
[04:05:05] <mozmck> The keys are upper, but values vary.
[04:05:32] <mozmck> LINEAR for TYPE, but inch for LINEAR_UNITS
[04:05:43] <mozmck> etc.
[04:08:06] <mozmck> It makes sense though that values could vary. Filenames need to be case sensitive, but other values don't.

[16:20:41] <kwallace> Hello. I'm looking at arbitrary 2D probing and 3D probing. I would like to find out what the current status is to see what needs to get done to make it more mainstream.
[16:21:58] <seb_kuzminsky> kwallace: i think it just works, G38,
http://linuxcnc.org/docs/2.6/html/gcode/gcode.html#sec:G38-probe
[16:22:32] <cradek> I think I don't understand what you mean
[16:22:43] <cradek> say more?
[16:24:51] -!- greg_ has quit [Ping timeout: 246 seconds]
[16:28:28] <kwallace> I have routines I made for probing rectangular and circular objects which result in finding their center. I would like to go further by digitizing 2D outlines and 3D surfaces, but I'm hoping to not have to start from scratch.
[16:29:07] <cradek> http://linuxcnc.org/docs/2.5/html/examples/gcode.html#_smart_probe
[16:29:15] <cradek> smartprobe.ngc in the distro is pretty neat
[16:29:42] <cradek> it tries to minimize the motion used to probe a grid
[16:30:15] <cradek> probing around an arbitrary 2d shape sounds hard but cool
[16:30:42] <cradek> once you have that, you can do 3d waterline probing
[16:37:28] <kwallace> Probing a circular boss turned out to be harder than expected. I do three narrow probes in X to get a very rough calculation of the center of an arc. Then if the arc is fairly shallow I do another wider scan to get a more accurate center. The final scan is on X and Y centers.
[16:37:33] <kwallace> I need the narrow scans in case I'm probing a small pin which the wide scan would miss. The narrow scan seems to be too course to get an accurate center. As the shape becomes less known the factors I need to consider increase.
[16:38:51] <kwallace> Hmm, I found this too,
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ProbeKins
[16:40:53] <cradek> probing around an arbitrary 2d shape is an interesting geektrap
[16:42:13] <cradek> it seems like you can maintain an approximate edge normal perpendicular to the previous two points
[16:42:41] <cradek> and just walk around the shape with it
[16:43:27] <cradek> sharp inside corners will be tricky
[16:43:42] <kwallace> https://www.youtube.com/watch?v=RZGP7zNWq-I
[16:44:50] <cradek> that looks like smartprobe's algorithm
[16:45:06] <cradek> very weird that the probe tip isn't round
[16:48:43] <pcw_home> Video aspect ratio problem?
[16:51:44] <cradek> oh maybe so
[16:53:44] <jepler> the video area seems to have an unusual ratio of ~1.2:1. scaling the frame so it has a 16:9 ratio, the probe tip is more spherical
[16:53:57] <jepler> but the thing being probed no longer looks like a huge fake molar

[16:59:38] <kwallace> Thank you for the link, I have some homework to do.

[19:54:41] <andypugh> Oooh, that looks like the one...
[19:55:01] <skunksleep> Maybe get with Tormach?
[19:56:11] <seb_kuzminsky> my pathpilot source is from 2015 Feb 23, so it predates that release note
[19:56:26] <skunksleep> I could email rogge and see if we could get a diff
[19:58:29] <andypugh> I already did :-)
[19:58:37] <seb_kuzminsky> they will surely send us their linuxcnc changes
[19:58:39] <seb_kuzminsky> thanks guys
[19:58:41] <andypugh> (Actually I asked them to push the fix)
[19:58:48] <seb_kuzminsky> perfect
[19:59:04] <skunksleep> Awesome
[19:59:17] <seb_kuzminsky> i bet the bug is in 2.6 too, andypugh have you tried your carousel branch (or at least the remap part) there?
[20:00:03] <skunksleep> It was Google.. I searched for the error
[20:00:33] <andypugh> I haven’t tried it, but the config is a standalone thing except for the carousel comp, so it’s easy to test.

[20:04:05] <skunksleep> andypugh: it only happens in mdi?
[20:06:10] <andypugh> I haven’t tried it from G-code. That’s a rather obvious thing that I failed to try.

[20:17:03] <andypugh> I can’t help feeling that Norbert might need a few hints about robutsmess and maintanabililty.

[21:09:20] <seb_kuzminsky> i'd rather take it slow and get it right, than rush and fuck it up
[21:09:27] <jepler> I want to pass my new version of the arm memory ordering patches under seb's nose, as well as the guy who was helpful on the thread
[21:09:49] <seb_kuzminsky> i'll gladly look at it
[21:10:44] <jepler> seb_kuzminsky: branch jepler/arm-atomic
[21:10:58] * seb_kuzminsky fetches
[21:13:12] <jepler> I sort of suspect that fifo->out also needs to be given the atomic treatment
[21:13:13] <seb_kuzminsky> have you tested both with & without stdatomic.h available? (old & new platforms)
[21:14:01] <jepler> yes, it built on odroid u3 (no gcc 4.9), on debian jessie (gcc 4.9), and presumably on the buildbot
[21:14:09] <seb_kuzminsky> ossom
[21:14:29] <jepler> one problem with my system of #ifs is that it won't detect what version of clang, if any, supplies <stdatomic.h> without requiring -std=c11
[21:14:53] <jepler> afk
[21:17:05] <seb_kuzminsky> those two commits look fine to me

[21:34:19] <jepler> hm on reflection I bet ->out also needs to be atomic
[21:35:10] <jepler> thread 1: read last bit of data from sample, increment ->out thread 2: check for space via ->out, write first bit of next sample
[21:36:19] <jepler> if the increment can be moved before the read, then the wrong (newly overwritten value) could be read

[21:45:16] <jepler> a much less likely bug to catch by looking, since it would only occur when running with a full queue, as opposed to an empty one

[21:55:30] <jepler> seb_kuzminsky: oh and there were more hm2 eth commits, but I'm not sure the branch is in final shape. after I went looking for the reason for intermittent startup problems, I found bugs..
[21:56:32] <seb_kuzminsky> i thought skunkworks found the last bug the other day
[21:56:39] <jepler> origin/2.7..jepler/hm2-eth-startup
[21:56:42] <seb_kuzminsky> who ordered this one?
