motor phase A/B disconnected on driver - AFTER single Z motor



  • I have this issue after switching my printer to a single belted Z motor. The Z will not move at all and will spam Motor Phase A/B disconnected in the console. I plugged the other motor back in and now it works fine. Is there some setting I need to change? After searching I see some mention of jumpers - but I don't see anywhere to place jumpers nor do I remember seeing any with my duet.

    FW info:

    Top right corner of the DUET board in the image shows jumper placement.



  • Ah i see. So I just need to make a jumper to short the outer 2 pins together? just want to confirm before I go shorting things lol.

    It should have come with 2 jumper for the purpose, but if you have some spares laying around from a PC or other electronics device?
