Seems like an odd thing to use a CNC for, but I would think it could handle it. Just not sure how to do it in VCarve Pro.
I make all manner of cutting boards, serving trays, etc. I cut the finger relief in the sides of the boards with a 1/2 rabbet bit as shown below. Anyone ever tried such a task on the cnc with the board laying flat? The software seems intent on simply doing operations on the top of the board, not the sides.
You can do it, but Vcarve does not directly support that bit or operation. If it is just a plunge cut, you make a line that is in and back. You define a dummy bit and tell Vcarve to make the cut ON THE LINE, 0.0 depth. Preset the depth before you cut. The bit will go in and out. Try setting up the motion in Vcarve with the animation very slow.
Personally, I would make the cut on a router table. Easier to accurately set up, and I think safer.
