Hi Roman,

5-wire would definitely be a problem - one common for all
windings - but 6-wire sounds ok, if you simple think of doubling
the scheme shown above. Got any idea how popular 5- vs 6-wire
steppers are?

Further, with 2 L293's on the pcb, seems you could handle
2 5-wire steppers ok by driving 1/2 of the windings of each
stepper from one of the L293's and the other half from the
other L293. The common of one stepper would be hi and that
of the other would be low, of course, so I imagine the
control s.w. would be mirror images, or else you would have
to shuffle the order of the windings.

Would this be too much trouble?

best regards,
