I think this is getting off topic, but the CNC pcb etcher is a
deffinate topic for this list.
I thought of painting a pcb with dykem then just erasing it with the
plotter. drilling holes still poses the problem.
Seems any head could be used to drill, the lighter the better as that
would put less pressure on the low powered steppers.
