      I am struggling with my new Duet3D 3 board I received last week. I am hooking it up instead of my Ramps 1.4 board and managed to boot it up with a Pi4 as the SBC.

      I have made all the connectors and connected all my motors to the board (Driver 0 = X, Driver 1 = Y, Driver 2 = ZA, Driver 3 = ZB, Driver 4 = Extruder).

      I am somehow getting constant errors on Driver 3 and 5, they either complain about out of phase A/B, or simply do not move the motor. The problem is tho, if i hook the Nema 17 motors up to the other ports they move fine, also swapping using confirmed working cables. I started using driver 5 as I thought hey might be a bad driver, but also driver 5 refusing to run any motor.

      I am running the latest 3.0.1-RC3 firmware I think (bit unclear in docs all). What am I doing wrong, could it be that the board is broken? The diagnostics does not seem to indicate any timeout or problems with the driver?

      Here is my config:

      ; Configuration file for Duet 3 (firmware version 3)
      ; executed by the firmware on start-up

        @renarj check you have connected the ZB motor to the correct driver, the physical order of the drivers on the board isn’t necessarily what you expect; it’s
        0 1 2
        5 4 3

        So driver 3 is behind driver 2, not behind driver 0.

        See the wiring diagram here: https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/TF1FBCbopEsxvYAv.huge

            It's an easy mistake to make. The "obvious" order made the PCB routing more difficult.

              I (paper) printed a copy of the main image on the page "Duet 3 Mainboard 6HC - Wiring Diagram" and hung it on the wall next to my printer. It's useful for identifying specific connectors AND for identifying the wiring needed for specific pins.

              (My copy also has notes on what's connected to which connector, etc. )

              https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Wiring_Diagram

              (edit: fixed the link to go to the mainboard, not the expansion board)
