      Have been busy for some time with other pressing issues.

      Last weekend I adopted the advise of fcwilt I modified the Config.g file using only one Z-motor (on mainboard driver 0). Then using an extra motor I tried to get it stepping.
      It turned out that the cabling and crimping was the main origin of the problems.

      One cable had to high AWG. That made the stepper squeek and respond differently on commands and got it quite warm.
      I checked, recrimped all wires, now I have 4 working cables for the steppers.
      Next I tested every driver connection to the mainboard.

      Now I have three drivers working however the last one (driver 1 on mainboard) did not react to any stepping request. When requesting a large step, the system returns an error message.

      9d61a18e-2d6f-46ef-8e9f-e97ffd65ac12-image.png

      Exchanging the cables did not have any effect. The cables are now working like a charm except on driver 1.

      I have been careful with the motors not to rotate them when connected to the board.

      This has all been done on 3.2. After my finding I decided to install 3.2.2 for the mainboard and the expansion boards. But helas no improvement. The other drivers still perform correctly. Driver 0.1 keeps on having issues....

      Did I fry my driver in some way?

        Anything is possible, but let's eliminate cabling first since that's the most likely issue. Is there anything visibly different about that driver header? Is the crimp making good contact?

          I have 4 cables for the 4 motors,
          I'm using driver 0.0 0.1 0.2 and 0.5
          Modified my config.g so that I test driver by driver with any of the 4 cables
          In total I test 16 times with a stepper. Every driver with any of the 4 cables.

          Testing all cables on 0.0 0.2 and 0.5 and rotating/testing all 4 cables work perfectly in
          Connecting any of the 4 cables to 0.1 results in the same error as shown above.

          Because of this I conclude the cables are okay.

          The connector on the motherboard looks very similar to the other connectors.
          Nothing special there.

            Thanks for the clarity on your testing. Before we conclude the driver is failed, can you share your current config.g? Just in case.

                I know we've had issues previously, but had this driver worked before at all?

                I can't see anything obvious in the config.

                Please contact your vendor and initiate a warranty exchange. Include a link to this thread as authorization.

                  @ahwitmer said in Stepper definition Z motors:

                  M906 X3200 Y3200 Z2240 U3200 V3200 E1360:1360:1360;1360:1360:1360:1360 I30 ; set motor currents (mA) and motor idle factor in per cent

                  there is a ; instead of a : in the E definition

                  and all your thermistors are not corrrect B4138 is the default. look up the correct value in the thermistor documentation.

                    @Veti Eagle eye! That's a good catch, but I'm not sure it will have an impact on driver 5.

                      @phaedrux @Veti Indeed eagle eyes, great modified it.

                      I'm aware that I am using the default values for the thermistor. I'm taking it step by step.
                      Configuration via RRF config tool, then step by step modifying the parameters of the elements.

                      After changing the ; for a : and modifying the thermistor data, the problem with driver 1 stil remains. 😰

                      I will contact Duet3D

                      Thanks for the support.

                        Phaedrux, your suggestion was to ask for a warranty exchange.
                        I did ask for the exchange, the company seemed to be not too willing to help out. Luckally they checked with the people of Duet3d and I could exchange my controller board.

                        Although the card seemed to be used already, the problems were over. My four Z-motors are finally working correctly without any flaws.

                        It was somehow surprising to see that the temperatures measured by the NTC's were significantly different, although I used the same parameters as before. But that is a next step.

                        Thank you very much for your help solving my problems! Again many thanks!

                        This topic can be closed, problem solved!
