I’m trying to cut some basic shapes out of copper. Four end mills later and the machine seemed to be working well, except it was cutting very far into my wasteboard after the second or so pass. It would get through the copper cleanly and then continue to cut into the wasteboard. My material is set at .6mm thickness, and I know this is accurate because I’ve measured it with a caliper. Why is my machine cutting so far past the max depth? I’ve attached an image of my setup from Carbide Create. Any ideas?
