What is causing this problem (see attached picture)? Brand new CNC. Have tried different cutters/bits. Have changed different speeds, plunge rates, pass depth,... Have cut first rough and then full finish cut (with offsets). Still same problem. Same problem in all inner corners if cutting shapes not circles.
Second questions: If I make circle 10cm diameter and using correct bit I get 10.050cm circle, is that difference ok for high price precision CNC?
