Solved-First time setup. Cant get steppers working properly



  • Hi All,
    First time Duet user and just getting it set up on my BLV Cube. I wired the steppers according to the example on the BLV site, i.e. Blue, Red, Green, Black
    When I test them using the
    G91
    G1 S2 X10 F3000
    example the carriage moves to the right rear as it is supposed to.

    However when I try
    G91
    G1 S2 Y10 F3000
    the carriage does not move at all -- the motors just grind until they stop. It's as if they are woking against each other.
    I tried setting the Y motor to S1 rather than S0. No difference.
    I tried all kinds of wiring changes and swapped X driver for Y but one of the axis always grinds with no movement.

    Any help would be appreciated.

  • I believe the Y stepper is not wired correctly.

    From Duet Literature:
    Identifying the stepper motor phases
    Here are two ways you can pair the stepper motor wires into phases:

    Use a multimeter. There should be a few ohms resistance between two wires that belong to the same phase, and no continuity between wires that belong to different phases.
    With the motor wires not connected, spin the spindle between your fingers. Short two of the wires together, then spin the spindle again. If it is much harder to spin than before, those two wires belong to the same phase. Otherwise, try again with a different pair of wires shorted together.



  • Thanks bricor
    It actually was wired correctly. What I found is that when I was switching X and Y one of the pins for Y had pulled loose. Once I reconnected that I was able to get them operating correctly.
    This is my first post here. How do I edit the title to show it is solved?
