Cant connect DM542t to Duet2
-
i want to connect a Nema23 with external power supply and a dm542t as Driver to my Duet2 but the steppermotor spins only in one direction. If i test the Motor with forward and backward motion the motor turns forward and when it sould turn to the backward direction, it is also going forward but a little bit slower.
Can anyone help me with this problem?
If i connect a nema 17 direct to the Duet2 it works normally.
Maybe some grounding issue?
The wiring looks like this: -
@Nicogr you can't connect it like you have.
you'll need to use something like this https://docs.duet3d.com/en/Duet3D_hardware/Duet_2_family/Duet_Expansion_Breakout_Board -
@jay_s_uk Thanks a lot for your reply, i will test it soon.

Do you Know if the Wiring with the expansion board is correct?wiring1.pdf
I cant move the motor

@Nicogr the second page looks correct.
Can you post your config? -
Thank you so much for your lightning fast response.
My config looks like this:

The Motor is spinning. I had to swap the ENA+ and ENA- cable

@Scara_Arm when using drivers with single-ended opto isolated inputs, it is better to use the alternate wiring scheme between the expansion breakout board and the external driver. See https://docs.duet3d.com/en/Duet3D_hardware/Duet_2_family/Duet_Expansion_Breakout_Board#signalling-voltages.
