My current project is a small PCB drilling machine. I am not looking
for real power and these would seem to be around teh power of a
NEMA23 triple stack or NMEA34 single stack stepper ? I'm assuimg 10-
15 watts would compare.

But, the big question is how to drive them cheaply !

Has anybody hacked the driver board and controlled it directly ?

I never thought about the output of a CAD program like HPGL as a
driver software.

Also, since it has a pen up/down signal it may be possible to convert
that to a self contained peck driller driver.

I could not find any manufactures markings so am not sure if they are
Hathaway.
