      Unless you have remapped axes using M584, driver 1 is the Y axis driver. Is the Y axis moving normally? Is the error message triggered by particular movements, for example rapid Y axis movement?

      Please send command M569 P1 and report the response.

          What have I done wrong again 😞

            Y seems normal. Yonnected to y x to x z to z and e to e0 is that correct or am I lossing it.

              there you can see that driver 1 is Y

                Thanks, getting a new error code now which reads. Error: short-to-ground reported by driver(s) 3.
                and the extruder stepper motor dances about like a bee at a hive. Any ideas. I have tried two stepper motors one brand new with the same result.

                  Four likely possibilities:

                  1. Stepper motor phase wires have been mixed up. This happens easily if the stepper motors have connectors on them and you bought the cables from a different supplier (or even from the same supplier in some cases).

                  2. Faulty stepper driver chip. If this is the problem, the fault is likely persist even with no stepper motor connected to that output.

                  3. An actual short between the stepper motor wires, or to ground.

                  4. Using stealthChop at too high a speed. This could give the short-to-ground error at high speeds.

                    Thanks for the reply. If it is a ground problem how would I fix it? Also were are the settings for stealthChop located. Cable seems OK so that's may be out of the equation. Also how do I change the stepper for the Extruder to the spare one. Simple questions but not being familiar with the configuration of the Duet it is a bit of a learning curve as I am sure you will agree. Thanks for the help.

                      see the first reply.

                        The settings for stealthChop are in M569. Your M569 response indicates that it will switch to spreadCycle at 4.7mm/sec, which is reasonable. So I don't think your stealthChop settings are to blame.

                        The simplest way to change to the second extruder is to locate the M563 command in config.g, and in that command change D0 to D1.

                          If it is indeed a grounding issue as you mentioned how would that be resolved

                            Using D1 extruder works fine. So how do I cure the D0 connector error please.

                              if another driver works then this sounds like a warranty case.

                                I agree. @Veti, I suggest you submit a warranty claim.
