Hello,

My name is Paul Hollister and I am a CAD instructor in Tacoma WA. There is a ShopBot that has been sitting for quit awhile and I am firing it up. I am cutting geometry.....dxf from AutoCAd into PartWorks. I am having a Z Axis problem. It falls off....meaning, it first does not go to the full depth and each contour it gets more shallow...less deeper into material. Any ideas?
