Re: cutting plexiglass #mill

Eagle 9.x free edition limits board size to 80 square cms - i.e 10cm by 8cm. Not unfortunately 80cm x 80cm!!

Board outlines I mill by making the outline larger than required by 1/2 the end mill diameter.  Replicate the milling gcode for each complete pass, increasing the Z parameter by a small amount (say 0.25mm) for each pass up to the board thickness or just beyond. This will just free the board and barely mark the sacrificial base board.
