[00:06:35] <jepler> bpuk:so I just basically made _logDebug unconditionally fprintf(stderr, fmt "\n", ## args);
[00:06:40] <jepler> and that gets me debug info in the terminal
[00:06:57] <jepler> don't forget, you can attach to milltask or rs274 with gdb to debug too
[00:07:07] <jepler> e.g., after starting linuxcnc, gdb -p `pidof milltask`
[00:07:17] <jepler> or if you want to run rs274, gdb --args rs274 -g test.ngc

[21:45:25] <bpuk> jepler: Thanks - that works!
[21:46:06] <bpuk> andypugh: for info - I put a pull request in on the G71 branch. That should bring us back to where I was in 2012
[21:46:54] <bpuk> andypugh: working on getting it moved over from named lines to o-subs. I think that most of the breakage will come from there so seems like the best place to start
[21:51:22] <andypugh> I am not sure how it works with C++. My Python mock-up was just: regex= r'\O0*%(p)i\s*SUB(.*)O0*%(p)i\s*ENDSUB' % words
[21:51:22] <andypugh> gcode = re.findall(regex,open(s.file).read(), re.M | re.S | re.I)
[21:51:23] <andypugh> gcode = gcode[0].split('\n')
[21:52:13] <andypugh> But then I was not trying to be robust at all for the bit I am playing with.
[21:52:55] <bpuk> been trying not to think about type2 - looks like the 'obvious' way is to subdivide on points of inflection and run each segment individually
[21:53:05] <bpuk> almost recursive
[21:53:20] <bpuk> makes sense for a mockup - doesn't matter how you get the profile in ;)
[21:53:24] <andypugh> One side-effect of using O-words is that I think that the profile can actually be in a different file.
[21:53:46] <bpuk> yeah, it certaintly can - is that good or bad though?
[21:53:55] <andypugh> O nn CALL can look in many places
[21:54:19] <andypugh> I think it might be good. You can imagine keeping a library of profiles.
[21:54:39] <bpuk> and if it's a one-off, then define it in the same file?
[21:54:55] <andypugh> Needs thought :-)
[21:56:16] <bpuk> been thinking about how to define the profile as being in an arbitrary plane too. I'm leaning towards making it a class rather than a simple struct
[21:56:42] <bpuk> and yes, yes it does
[21:57:22] -!- kingarmadillo has quit [Ping timeout: 268 seconds]
[21:59:54] <andypugh> Arbitrary plane does’t seem to hard
[22:00:16] <andypugh> # Be agnostic about plane.
[22:00:17] <andypugh> planes={170:('X','Y'), 180:('X','Z'), 190:('Y','Z'),
[22:00:17] <bpuk> simple way is take the first two axes used
[22:00:18] <andypugh> 171:('U','V'), 181:('U','W'), 191:('V','W')}
[22:00:19] <andypugh> for g in s.gcodes:
[22:00:20] <andypugh> if g in planes:
[22:00:21] <andypugh> p, q = planes[g]
[22:01:00] <bpuk> and error if a third axis is used
[22:01:10] <bpuk> pretty much
[22:01:15] <andypugh> Though that’s not arbitrary, it uses the G17-G19.1 setting
[22:02:07] <bpuk> for the lathe ops I'll need at least (X, Z ), (Z, X), (U,W), (W,U)
[22:02:13] -!- marshmn has quit [Ping timeout: 248 seconds]
[22:04:00] <andypugh> Slight wrinkle, yes. The planes are normally called 17-XY, 18-ZX, 19-YZ but the G71 / G72 distinction is on whether you feed in Z or X. Now if G18 G71 feeds in Z, does G17 G71 feed in X ?
[22:05:32] <bpuk> ideally I'd want (X, Z ), (Z, X) to both respect G18 for movement, but flip inside the roughing function
[22:06:10] <andypugh> bpuk: I think this is just something to document and be consistent about. G71 should probably feed in Z for planes with a Z in them, G72 feeds in the other one, and the other combinations go by a fixed (but almost arbitrary) convention.
[22:10:21] <bpuk> makes sense
[22:10:48] <bpuk> other combinations go in alphabetical would do - that way it's consistent at least
