      @Phaedrux funny thing is, i only put new board connectors on x,y. z axis homes just fine....z was not involved in what i was doing. the board connector wiring is the same on x,y as it is on z. this just gets curiouser and curiouser. I'm going to call it quits for tonight. Try again tomorrow.

        can you post picture of the cable connection on the stepper and the duet.
        also please post the model number of your stepper drivers.

          Can i make a general suggestion. Can you please keep a log of the changes you are doing.
          This will allow you to better retrace your step on changes you have made.
          So if your printer was working a week ago, you made some changes, and then realised its not working anymore that you can revert those changes.

                    @Veti yep, that's my stepper. i still cannot get the image of my board wiring to upload. both were jpg, taken at the same time. anyway, my stepper wiring at the board, from left to right is red, gray, yellow, green.

                          from the spec of the motor i read that yellow and red should be one phase and green and grey.

                          if that is true. your wiring is incorrect.

                            @Veti my z wiring is the same, and it functions fine.

                                  just to make sure. you measured while the cable is plugged into the motor?

                                  is there any resistance between the yellow cable and any other cable?
                                  can you check directly on the pins of the motor?

                                    green/yellow: 2.4 ohm
                                    red/gray: 2.4 ohm
                                    measured directly on motor pins
                                    rechecked at board ends.....no ohmage (sic).....bad crimps or break in wire someplace?

                                      @swrightlast said in STEPPER AND HOMING PROBLEMS:

                                      green/yellow: 2.4 ohm

                                      so you had no resistance with the cable. this suggest that the cable is broken.
