First I want to apologize, but I am a greenhorn in the world of CNC. I have been using my Xcarve (1000X1000) without an issue. The last two pieces I’ve tried to cut have been terrible on the flat surfaces. I have the Dewalt 611, 1/8" straight bit, Recommended settings, and the router speed set at 2. I replaced the bit and checked the collet, it’s tight. I’m not sure what to do. Any suggestions are appreciated. Thank you!
