[Swansea Hackspace] 3D CNC milling?

[Gerrit Niezen]

Dave: Thanks for the link to the Youtube videos, they’re now on my to-watch list. I should probably have mentioned that I’m specifically looking for decent open-source software - for closed-source stuff I’d probably use Fusion 360.

Tim/Justin: I tried generating the toolpaths using the demo model loaded on PyCAM - it took 6 hours on my Ubuntu box (but at least didn’t crash). I wish Heeks had a better UI.

Suggestions for buying end mills - eBay?
