John,

Just tested the "arc theory" and can confirm that milling layers contain the necessary GCODE.

Of course due allowance will be needed to allow for tool diameter, and the GCODE will need to be edited to set correct cutting depths for multiple passes.  Personally I set this to 0.3mm when using a 3mm diameter tool and normally set the lowest cut to 0.1mm below the bottom surface.
