- This has been done before. :-) And it is not necessary to turn the
- x-y yourself. All you need are the (x,y) co-ordinates of the PCB on a PC,
- which turns stepper motors, to the right location; then another stepper
- lowers and lifts the drill. That way, you can prototype quite fast a
- number of PCBs consistently.
