      Hi

      I'm not sure if I destroyed the extruder motor driver on my new Duet Wifi. After testing all functions, the extruder motor made some strange noises. I find out that the extruder phase cables are wrong connected to the 4pin connector. The Duet reported a Phase A short to ground error. After that I plugged in the cables correctly. Unfortunately the error still appears. The motors phase resistance is 3mOhm (both phases) as it should be. I also measured the phase resistance on the Duet board. One phase of the faulty motor output only have 3MOhm resistance. All other phases (also from the other correct working motor drivers) have a resistance of approximately 12MOhm.

      Is the motor driver destroyed?

      Many thanks in advance

      Best regards

      Michael

        @buckker sounds like it. can you post a high res picture of the driver with the issue?

          Yes, of course:

          The E0 driver is faulty.

            @buckker no scorch marks but i've seen drivers fail without them.
            it would need a repair i think.
            you can always use driver E1 instead if you're not using it

              @jay_s_uk Thanks for your help. I already use E1 for the second z-axis motor. Should I pay attention to something special if I buy a replacement chip?

                @buckker no, nothing i'm aware of.
                You'll need a hot air station and a heated plate to be able to change the chip

                  @jay_s_uk @buckker the TMC2660 doesn't have a thermal pad underneath, so it's also possible to remove the old chip using low melting point solder such as Chipquik.

                      thanks to all

                      Do you have a source for a original TMC2660 chips? My favorite electronic store is out of stock....

                          Is it possible that the TMC 2660-PA is no longer in production?

                          Does the TMC 2660C-PA also works? This driver is available at Digikey.
