So I have a 1.25inch/31.75mm surfacing bit I wanted to add to tool library and use to surface a board.
I added the tool, and created a pocket tool path, zeroed the machine and reset x,y,z axis, but when I go to run the file, it starts no were near the surface. It’s above by about 2 inches.
This is strange, it looks fine in NCviewer, surfacing at -0.5mm as you asked. Did you restart Carbide motion and rehome the machine after disabling the bitsetter?
