Expansion stepper Breakout + TB6600

Corvonero

I connected the Expansion stepper Breakout to my Duet Wifi, I wired my Tb6600 Stepper, i remapped the Z Axis but nothing happened, my Nema doesn't move.
I need to connect 4 Tb660 to connect my 4 Nema to move the Z axis of my Big Printer.

Those connections look correct to me. How did you remap the Z axis? Did you get any error messages when you tried to jog the Z axis?

i used M584 Y2 Z5:6:7:8

When i try to move Z axis stepper motor doesn't move and i didn't get any message

Did you use the T parameter in the M569 commands for the external drivers, to increase the step pulse width? Most external drivers need this.

I've Tried with M569 P5 R1 T3 but nothing change

I've mesured with the multimeter Dir - e dir+ and it says +3.3V when i go "up" and -3.3V when i go "down". but my stepper motor doesn't move
