	The determination for overlap should be based on the clearing of copper from the board. A generated CNC job could leave large uncleared islands like the image below. A smaller overlap percentage could generate a CNC job with fewer missed islands of copper that would make following PCB production steps harder.

Edge Milling

@@ Line 186: / Line 186: @@
 Edge milling is performed with the 1.5mm burr.  These are inexpensive carbide burrs originally intended for use with fiberglass, but they can be used with the PF material preferred by the makerspace.
-Manually entering parameters for edge milling is important because the software likes to crash if a tool is deleted from the tool table when performing edge milling.  The following parameters should be entered instead of imported from the tool library:
