Heekscnc keeps crashing can anyone suggest other free 3d cam programs?
Have you spent any time looking at PyCAM? It’s rough around the edges and likely still being developed.
I don’t know anything about makercam, and, I can’t look at it one my phone, but, it is worth a look.
I downloaded pycam, but I haven’t invested any time because it looks so rough around the edges.
Someone (?) on the shapeoko blog covered it a bit and compared it with freecam vs meshcam.
It’s not free, but you should probably take a look at Cambam …
Autodesk’s fusion 360 has HSMExpress all for free (for noncommercial or startups)
Cambam have free solution. Scroll down in download page and you see.
I haven’t really used any of them but I have been looking at: BlenderCAM, Openscam, and Makercam.
I use CamBam and love it, however only have done 2.5D stuff. There is a free version available as well.
I have been happy with heeks, maybe try on a different computer
