short-to-ground reported by driver 0 1 2 4. Help Needed



  • I am new to the Duet board but have been building CNC machines for a while. This is a new install of a Duet 3 6HC on a newly created printer.

    Whenever I try any motion the short-to-ground error is given. I have tripple checked all the wiring, tested the motors and wires on other systems and also used a meter to check/verify the wiring and coils in the motors. There is no short in the wires or motors.

    I am at a loss. I have searched forum and found others with similar errors but they usually had wiring issues. I don't all the motors work, tested individually on the good driver channels.

    Here is my configuration file and a list of the errors.

    @maxspongebob sorry for the inconvenience, this is a known issue with a short run of boards. Please see this thread for info and what to do: https://forum.duet3d.com/topic/18011/duet-3-6hc-short-to-ground-issue?

    In short, contact Duet3D for a warranty replacement.
