Hi!
Is possible to use dual pololu A4983 driver for control 2 stepper but with a single DIR&STEEP signal?

Attached a a schema about needed.
Sorry i'm don't know about electronics sad smiley

Thanks!

Do you want the 2 steppers to perform the same moves always ?

If so you could wire these both to a single pololu.

Yes, its for same moves, but exceed 3A and pololu drivers max is 2A Each stepper is 3.6V 1.7A/phase
Maybe a 4A driver with same pinout as that pololu driver? where to find?

I believe just stacking boards has worked for some people, search the forum. Have you tried wiring them in series?

On re-read this makes less sense than in my head. Wire the motors in series if NOT using two boards. If you use two boards you need to wire them in parallel.
