      Whenever I try to home the x/y axis it gives me an error message: Warning: motor phase A may be disconnected reported by driver(s)
      an

      I checked all the connections and the polarity is correct(I will attach the sheet and picture to verify this). I tried different motors to no avail and I made sure that my config is correct which I will also attach.

      The only thing that happens is that when I home from the duet web control, one of the motors starts to vibrate but not on the paneldue control

      Here are the images

        @mrcat07 does your motor have a connector on it or is it hardwired? either you have a broken wire, bad connector/crimp or your motor plug is wired incorrectly at a guess.

          @jumpedwithbothfeet Yes it has a connector. It does come it out when I yank it even when crimped properly because of the fact that the spring on the crimp end is not very strong. But even when i replace it with a precrimped motor from filastruder, nothing works.

          If you looked at the diagram I put in the imgur as well as the image, all of the connections are properly done so this issue is very frustrating for me.

            I suggest you use this method for identifying which wire pairs are which and then wire accordingly.

              @Phaedrux I did that and all the connections are correct, the motor is hard to rotate when the polarities are on either side just like on the wiring guide. Still doesnt work. alt text

                What do your crimps look like?

                Is this a new build or was this previously working?

                  @Phaedrux This is a new build.

                  When I put a motor that already that connector out of the box, it still doesnt work which indicates that with good crimps it still isnt working.

                  When I connect the motor that is on the actual machine itself and I put the command to home x, it moves slightly forward, stops then says the phase error.
