FEED RATE When cutting woods on a STEPCRAFT I always suggest setting this to 1/2 of the maximum machine feed speed. So for a Version 1 machine this will be set to 15 mm/sec and for a version 2 machine you will set this to 25 mm/sec. Keep in mind that End Mills are meant to cut from the side whereas drills are meant to cut vertically
