If your first cut is X-, then retract, move over make the second cut the same. Make all step overs the same as well, keeping the conditions between the workpiece and the cutter as close to the same as you can. I know on my old mill that is the only way i can achieve a decent finish. Otherwise i end up with steps, and tool lines.
