Duet2Wifi driver 0 gets very hot



  • Duet 2 wifi v1.04c
    Duet Web Control 3.1.1
    Printer: BLV Cube CoreXY

    New board, after connecting to 24V I found that the x-axis motor refuses to work and the driver gets very hot, Note that the driver heats up even when the motor is not connected at all.
    I switched to driver E1(4) and everything works fine but still driver X(0) heats up.
    I also crossed motors X/Y but the problem remains with driver X(0)
    firmware updated didn't help.

    Is there a chance to save the board?
    What should I do next?

    Here is my config

    you can do M569 P0 S0 R-1 to disable the driver, but I suspect it will keep getting hot until it lets the smoke out in the end.

    (to save the board you could replace the chip)

    If this is a genuine Duet purchased from an authorized reseller within the past 6 months, please contact them and initiate a warranty replacement. You can refer them to this forum thread. Sorry for the inconvience.
