I could probably do them on my machine if I could find suitably sized
carbide bits, which are both hard to find in those sizes, and expen$ive
at over a twenty a copy. But slowly I expect as the spindle speed is
only 2500 rpm max for the micromill. I think most machines for cutting
pcb's will have 20,000 rpm and up spindles & liquid or forced air
cooling. I believe there is a convertor program that can take a
png/gif/tiff image and make gcode to be fed to emc out of it, I've used a
similar one to carve fawncy nameplates out of door kicker brass sheet
myself. That one takes a line of text, and a path to a truetype font
plus a filename as the input arguments, and generates a gcode output file
