How can I change this? Do I make a mistake? > You have to offset the first move after the G40 by almost the radius of the cutter. Over the length of that move, the cutter offset is interpolated out, reaching zero at the endpoint. If you were to offset it by MORE than the radius, that would cause the "concave radius during cutter compensation" error. So, I usually put the last compensated move well off the edge of the workpiece, so when the move that ends the compensation is ending the compensation, it doesn't gouge the workpiece. Your G03 move is BEFORE the G40, so it is done completely within the compensation. It should be AFTER the G40.
