The last post I wrote here covered a common support question I get for the CNC Software (MeshCAM) that I develop- “How to choose a stepover value”. If you’ve never tried MeshCAM, give it a shot. He’s gone out of his way to create super simple user interfaces that ensure his users succeed in their CNC projects. In fact, that’s one of the great strengths of his software too. Robert’s forte, aside from creating wonderful software like MeshCAM, is making very complex topics easy to understand. Please welcome Robert Grzesek, founder of GRZSoftware and author of MeshCAM 3d cnc cam software for this guest post on the fundamentals of 3D milling toolpaths in CAM.
