      I don't know whhat to do because I tried to swapped wires many times.

      one wrong combination where you let one side of the h bridge drive against the other is enough to cause this issue.

      On every drivers and without plugged motors ?

        driver 5 and 6 are okay arent they? and yes, the error will persist after unplugging the motor if you got the "correct" wrong combination.

          I didn't test the 5 and 6 drivers yet. I reflashed and erase everything to test again but always the same message.
          With my Duet2 wifi, it worked before

            I think we can leave it at drivers 0-3 are damaged, and Duet people will determine the cause and potential remedy.

            (edit: 👇 shop will tell you to get Duet people to determine the cause, on this fourm)

              Ok I contacted the shop and see what we can do .
              Thanks for your help

                Unfortunately, swapping stepper motor wires over so that they are no longer wired with one phase to each end of the connector is a recipe for blowing drivers. This is because the driver cannot control the output current when they are mis-wired in this way. Sometimes they survive, sometimes they don't - it depends on the VIN voltage and the type of motor.

                  @dc42 ok I understand but the problem was present at the first plug and I used the same working wiring than my working Duet2. And the message was telling that the driver 1 was short - ground and I had never plugged anything on the socket.
                  I repeat, I swapped the wires because it didn't work with the same wiring as my Duet2.

                    I forgot to mention that the error message is present without the motors plugged ...
                    It is the Duet3 V1.01

                    Here is a photo of the plug. I tested the phase before plugging it.

                    Tape is provisory.

                    driver 0.jpg

                    What role does the tape play there? Is it possible the crimp was bad from the start and making a bad connection?

                    Were you getting the error before plugging anything in or only after?

                      @Phaedrux Tape is only a protection to avoid shorts contact. Contacts were good since I made continuity tests and resistance tests and I always had signal.

                        Were there any other error messages along with the short to ground errors?

                          @Phaedrux No, M122 had not error messages. Only those ground-short messages

                                    Thanks. Please try commanding the motors to move (without any motors connected) and repeat that. I am looking for the driver status to change.

                                        I have a similar issue, getting "Warning: motor phase A may be disconnected reported by driver(s)" on all drive ports with what were working stepper motors. Only possible mistake i made is connect one stepper motor to 3 pins instead of 4 ie offset one pin. Would this cause all drivers to die?

                                          Impossible because I tested all phases before plugging motor and I checked if these big crimps went on the right place when connectind them on the Duet,

                                            ref https://forum.duet3d.com/post/100507 and you should probably start your own topic if the error persist after disconnecting your motors (when powered down ofc)
