[12:45:44] <sliptonic> Hi Everyone. I was looking to add some functionality to FreeCAD Path workbench and it triggered a debate. I wanted to get your feedback:
[12:46:06] <sliptonic> I was looking to add probing and z correction similar to how gcodewrapper does it.
[12:46:33] <sliptonic> Generate a probe gride, run it to get the points, then import the points to correct a toolpath.
[12:47:07] <sliptonic> But others noted that gcode senders like bCNC do this directly and perhaps the functionality should be closer to the controller end.
[12:47:32] <sliptonic> Does linuxcnc have a mechanism to interpolate Z coordinates given a probe map?
[13:18:46] <rmu|w> sliptonic: authoritave is only the source, but i don't think so. i think i would have found said functionality in my explorations. there is a possibility for leadscrew compensation and backlash compensation
[13:21:59] <rmu|w> probably it makes sense to compensate for a tilted tables, but arbitrarily shaped "wobbly" table, does that even make sense for a milling machine?
[13:38:37] <sliptonic> rmu|w: bCNC has it specifically for engraving circuit board where the material thickness might vary slightly but the engraving depth has to be constant. I've seen similar for engraving brass plate.
[14:05:30] <KimK> What about torch height compensation (THC) in plasma cutters, is that related? Would looking at that help? There you could be cutting corrugated sheet metal.
[14:06:03] <KimK> Yes, I know it's an analog input, but, it's an input.

[15:29:05] <KimK> (To our web people)(?): I accidentally discovered a broken link on the SagCAD homepage ( http://sagcad.osdn.jp ) mentioning us. "A Collection of Links Related to LinuxCNC", leading to the broken link at http://linuxcnc.org
[15:29:53] <KimK> We could point it back to the wiki, maybe? I'm not sure what exactly should be done, but there you go.
