I'm using solidworks with solid cam and mach3 as my programs. I drew a part that is a simple shape with a straight cut and some curve cuts. The piece is 1/8 inch flat wood stock. The pattern is one profile cutting 5 passes stepping down till it cuts through. My question is when it cuts the curved parts it's not supper cleanness, it looks slightly scalloped. I was wondering if this is some kind of motor tuning thing or if my machine is not tuned properly, or for that matter built properly. Is this normal. How clean of parts do you get right off the mill. Am I expecting too much. Can anyone help. Thank you.
