 FlashCut CNC offers a user interface for positioning, zeroing, and running the G-code, however it has no CAM capabilities. This means that G-code must be hand written based on the location of holes.  FlashCut CNC offers a user interface for positioning, zeroing, and running the G-code, however it has no CAM capabilities.

If bonding is not permitted, slowing down cut speed may result in less blowout on the backside of the hole and a backing plate should still be used.
