I'm learning Mastercam at work off hours and have been getting along pretty well figuring it out. I am performing a contour operation with 4 finish cuts, and .060 Finish steps. I have my origin set to the top of the part. When I generate the tool path, it starts above the surface and ends on the part. I tries entering in -.060 for Finish steps but negative numbers are not allowed.
How do I get MasterCam to step starting at the surface of the part?
TIA,
Eric
