I agree with Alan (mostly). Your method of setting zero is iffy at best. First: you need a flat surface for zero. Looks like you may be on the curved edge of the work piece. Has to be flat area. Second: the paper method you use to set your zero is not accurate. Set your bit in loose, lower down to just above surface and let bit drop down to make contact and then tighten bit. Every time you change a bit, when the program ends and returns to zero, don’t cut power to stepper motors so it locks spindle in place. Raise spindle with software, replace bit, lower to near surface, let bit drop to touch surface and tighten. Third: what bits are you using? Looks like up-cuts and that is why your cuts are so fuzzy. What are your doc and ipm settings and spindle rpm. All makes a difference. Just posted this on two stage cuts. Check it out. 2 stage cut - #3 by JeffParish
