This will help prevent heat build up.

Yes! MeshCAM has a “machining margin” option and that specifies how wide the roughing pass is going to be. It doesn’t let you go less than the width of your bit, in the video I have a margin of .135, I think. In that video I am making 3 passes along the outer contour. The first and second passes alternate, the first to remove a slot’s worth of material, and the 2nd to expand that slot to the machining margin parameter. The 3rd pass is the final finishing pass, in the end I do two .015" fini…

Gantry Upgrade to C-Beam

I did a quick test of using pocket strategy to do the profile cut in a unused space on the material. I made a offset outline 40% of the bit diameter around my test object (bat symbol) and did a pocket cut with a 40% step over so it would do it in 2 passes. Cut at .39mm depth, 1016 mm/min, 18,000 rpm I wet with WD40 and vacuumed up chips I did the pocket cut for the first 90% of the material, then switched to a traditional profile strategy with tabs for the remainder. I could not make tabs au…
