For general interest.
Some pcb engraving/etching done recently using Eagle 8.1.0 and pcb to gcode ulp. Track widths and isolation set to 0.012" and engraved with single pas. Minimum hole size is 0.7mm. Tracks engraved using a 30degree carbide engraving bit set to cut to 0.008" deep. Spindle set to 18000rpm and 600mm/min for engraving and milling board cutout.
I think the engraving speed could be increased to nearer 1000mm/min without sacrificing quality - something to try on the next boards.

There is no problem, however simple, that cannot be made more complicated by thinking about it.
