I have owned my Silverback for about 3 years and in that time I have not been able to carve many 3D projects without issues. I can V carvel and Laser cut all fine.but,try to 3D carve forget it. When I try it skips whole areas, or for some reason decides to cut much deeper in some areas and the return to the previous cut and totally ruining it. I have ruined so much wood . I feel like I wasted my money on this. I have watched video after video trying to figure out what is wrong. The rough cut goes fine but finish is a total disaster.
