Re: using printer motors

Elliot,
There are so many printers out there! The newer ones
are controlled by a micro. CNC machines for the most part use
step/direction signals. The micro in the newer type printers
provide the control to the motor circuit. You need to cut traces and
add the circuits found on the sites I recommened to you. It is
obvious you are looking for some kind of magic! It won't happen with
the newer printers. Older printers have more discrete parts and they
can be rewired to do plotting and engraving.
