      Dear All,
      I am about to mount a big geared stepper motor on my prototype, but it is way too powerful to be directly driven with the onboard drivers. The motor that I would like to use is this one: https://www.oriental-motor.co.uk/Products/Stepper_motors/Stepper_motors/high_torque_2phase_motors_pkp/?&filter1=PLE+(Neugart)&feld055=64+Nm&arid=31010&dwn=artnr
      And a suitable driver should be this one:
      https://www.oriental-motor.co.uk/Products/Stepper_motors/Drivers/cvd2/?&filter1=Rechtw.+m.+Montageplatte&feld193=4.2+A%2FPhase&dwn=artnr&arid=20306&download=1
      Do you think that this set up will work in combination with the Duet Expansion Breakout Board?
      Thank you for your help

        the duet3 should be out later this year. the new tmc drivers on that should be able to provide enough current.

          @fm16055 It should work as long as the driver works with the voltages provided by the breakout board.

              @stephen6309 on the driver catalogue there is only this regarding the signal input :
              ◇I/O Signal Connection
              ● Input signal
              Use 5 VDC for the input signals.
              If voltage exceeding 5 VDC is applied, connect an external resistor R1 so that the current becomes 5∼15 mA. (AWO, CS)
              If voltage exceeding 5 VDC is applied to CW input and CCW input when the pulse input is open collector, connect an external resistor R3 so that the current becomes 7∼20 mA.

              I have red that the expansion breakout board is rated to have a 5V output. Am I right?
              Cheers

                The expansion breakout board provides two options. The first is differential outputs a little lower than 5V, typically 3.5V to 4V. Most 5V drivers work with this. But it can also provide single-ended 5V drive for those drivers that are not happy with less than 5V.

                  @dc42 Thank you for your reply. Sorry if I ask, but I am struggling in finding some documentation to use the breakout board in a single-ended configuration. Could you please provide me any useful link?

                    @fm16055, to use it in single-ended configuration, connect all the + step/dir/en inputs of your drivers to +5V from one of the servo connectors on the expansion breakout board. Leave the + step/dir/en outputs of the breakout board not connected.
