Yeah. I have tried and quit a number times. Poor stability has always made it unusable for me. Hopefully this time is better. Still, once I can successfully make a drawing, then what? What exists for CAM posts?
I have milled some basic things using the FreeCAD CAM on a ShopBot 2416 and small custom grbl based CNC. Many years ago now, but things generally look better now. Otherwise I have exported geometry and used external CAM software like VCarve
