Dear all,

I have 3x 3180-PI Slo-Syn drives from Superior Electric with matching motors.

These drives communicate together through a serial cable which daisy chains from one to the other and connects to the computer.

The drives work perfectly individually and are microstepping up to 1/256 step.

The communication through the serial cable does not allow me to have coordinated movement between the 3 drives.

The drives have input pins for step and dir, but going through these bypasses the microstepping logic.

Do you know of any 3-axis breakout board which would allow me to generate microstep pulses to the 3 drives simultaneously?

Of course, any other solution is welcomed.

Thank you so much for the help
