I wonder if instead of trying to do cartesian scans, put the board on some sort of a spinning disk and run the laser in a radial direction or a polar scan. Basically what is done on a DVD writer. You could keep the .001 spot size and just spiral in.
That way you are not wasting time with a bunch of stop and start motion. May be easier to construct as well.
