      Ah, six, but only four populated. Forget what I said about six, above

        Hi,

        This is how my Predator motors are wired to Duet2

        Thanks

        That is how mine is wired now.

          @Carlo There's no way to know if that is the correct order for the wires. It depends on the internal wiring of the motor.

          You need to plug the loom into the motor, and check continuity at the connector on the Duet end. You should have continuity between pin 1 and 2, and between pin 3 and 4, but not any other eg pin 1 to 3 or 4.

            Phases sound OK.

            You say those are six wire motors. Normally, the two extra wires are "center taps". Which would not be used on a Duet. I'm trying to think of a good way to verify that we have the coil (phase) pairs, and not the center taps. You sound like you grasp all this pretty well, and it is probably enough for me just to say "be sure we don't have a center tap".

            Do you happen to have any other stepper motors? Or stepper drivers? Time to do some very basic "swap and verify" things...

            I don't have spare drivers, I have a spare 4 wire stepper and a spare 6 wire, neither are the same unlabelled type steppers Anycubic supplies.

              You might try one of those plugged into the Duet, just to see if it turns smoothly, or makes the same noise. I'd unplug all the other steppers, just for debugging.

              Power off when changing motor plugs, of course.

                Hi,

                I was simply illustrating the 4 vs 6 wire on the predator motors and made no mention of how to wire...

                Thanks

                  Solved one issue.

                  One wire on the wire harness for the X tower wire was severed at the molex crimp underneath the insulation. Recrimped. Homes fine. Moving axes works fine.

                  Still running through other procedures and need to dial in bed leveling which I haven't tried yet.

                  I'm still having issues with the wifi module not turning on intermittently upon startup. For some reason, this also doesn't allow my PanelDue to send commands either. Display works but does not send commands to the main board.

                  This forces me to need to reinstall the firmware but only after I open up the top case and pull the power in leads to the duet main board. Otherwise, I cannot connect, even if I unplug the external wire to the switch/power supply. It's very tedious and has happened to me 3 times since owning the board.

                    PanelDue interface is a serial port (UART) that is part of the processor. WiFi interface is SPI. In other words, they are very separate. Both of them not responding is an indicator of a deeper problem.

                    Power supply ok? Things like that.

                      The main switch is funky. Sometimes doesn't fully engage and will not fully boot before the system shuts off and I need to rethrow the switch. I can play around with that possibly. What should I look for/test for a bad power supply?

                      If I need to connect to the main board to install new software, it seems that I can't do it without physically pulling the DC VIN wires into the board. Unplugging the external AC in plug doesn't seem to work. When connecting VIA terminal I get Incoming bluetooth module instead of usbmodem1411
