Hello ,

I am facing a rather peculiar issue. My cnc works flawlessly when profiling, pocketing, v-carving. When I try to make a 3d carving though i have a problem with the Z axis. The roughing path comes out fine but when I run the finishing path the Z axis gradually dives in the material as the project progresses. Needless to say that the preview in the CAM software comes out as it should correctly without any issues. I managed to make a couple of small 3d carvings throughout the 6 months I owe my CNCEST6040, but most of the times the project fails because of the z axis. Anyone who can chime in and point me to the right direction would be much appreciated.

I am running the machine via USB on a dedicated offline computer which runs windows 7 32 bit and Mach 3.
