Read OnWith most controls, this prior position must be at least the cutter's radius away from the first surface to mill. If using a 1-inch diameter cutter, for example, the tool must be at least 0.5 inch away from the first surface to mill. Note that with most controls, this prior position also determines the maximum cutter size that can be used.
