      Hello,

      for a couple of months now, my stepper motors where wired in factory setting which is:

      A+ A- B+ B-

      They were turning so I did not think there were any issue.
      However when I looked at the duet wifi schematic it turns out the wiring should have been:

      A- A+ B+ B-

      I then rewired the stepper motor and it was turning just like before. How is this possible? Shouldn't the stepper stall when the wiring was in the factory setting?

        If you swap the wires to one phase, the motor turns in the opposite direction, that's all. Similarly if you swap the A and B pairs over.

          @dc42 Yes thank you that makes sense, sorry that you needed to answer this trivial question.
