The whole openscad -> export menu is ghosted here. Is that nissing python stuff?

I looked that up and its 2d only for the newest Appimage. And what I need to do is definitely 3 axis on the mill. > That will give you a DXF that can be fed into > "dxf2gcode".

And if you want to play and learn somehing about freecad, steps are loaded read-only. You can make parts disappear or reappear but you cannot modify anything else. The latest version of pycam on sourceforge has been converted to 100% python 3. Buster or later, maybe. I have 6.3 according to synaptic. > Nik Thank you Nik Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
