      When I power on my servo motors while the duet is now powered on, I get a lot of noise on the step/direction signals of the expansion breakout board - enough that my servos are going crazy.

      This is bad because I use four servos on the same plug, and they get out of sync going crazy.

      Can something be done to control the signals when the board is not powered? - Like pulldowns or something?

        Don't you use the Enable signals too?

          Nope, my servos do not have a enable input.
