as I have stated several times now Gregg, an .stl and cura is not the end target, it has zero chance of making me a serviceable part as this will be attached to the side of a 90Kg BS-1 clone. So I want gcode to drive a cnc'd G0704 working on about a pound of solid alu. Or, since I've a mister on the 6040, possibly that mill since it can turn 24000 revs and probably do a better job with the mister keeping the tool free of gummy alu. freecad has an export menu that claims to do gcode, but it does not create the code, nor does it report any error I understand when going thru the motions. freecad screenshot attached. A simple torus shape, 50mm in diameter, 35mm tall, with a 28mm center hole. The terminal freecad is running on says: Path workbench activated PathScripts.linuxcnc_post gcode postprocessor loaded. the object Cut is not a path. Please select only path and Compounds. the object Cut is not a path. Please select only path and Compounds. Traceback (most recent call last): File "<string>", line 4, in <module> <type 'exceptions.RuntimeError'>: The given file is not a path Stack Trace: Traceback (most recent call last): File "<string>", line 4, in <module> Which might as well be swahili to me. To me the "path" is to the location where its to write the code file to, which does exist and has other content. But to freecad, apparently "path" is something else entirely. As for using github to register for the freecad irc channel, I apparently am not doing that right either. their registration sends me to github, but github wants my email address BUT when I fill in that blank, github says that address exists and refuses to proceed as I use github to pull LinuxCNC updates to master, and build it on my rpi4 to drive the 11x54 Sheldon. So github definitely knows who I am, so how does that supposed to be done? IDK. All I understand is that I am blocked from asking for freecad help on their IRC channel. They also have two other ident choices, but I don't feed the social media vacuums what s/b private info. My name is not Trump so I don't do twitter and I don't trust Zuckerburg, full stop there too.
