Y axis only moves partial way across bed`



  • This morning the Y Axis on my Ender 3 just up and decided to only move about 1/3 of the way to the front of the bed. And usually the machine homes to the lower left corner, now its wanting to home to the upper left corner. I haven't changed anything since it was working yesterday.

    Thoughts?

    Thanks,
    Pat

  • check the wiring on the motor.



  • Everything seems to be seated fully and correctly. Here is a link to a quick video that shows what is happening on a home all. The grinding you hear is the Y motor.

  • it could be a problem with the endstop.

    issue
    https://duet3d.dozuki.com/Wiki/Gcode#Section_M119_Get_Endstop_Status

    y might be triggered even if not at the endstop.



  • I haven't done anything since I shot that quick video. Here is the response from M119

    M119

    Endstops - X: not stopped, Y: at min stop, Z: not stopped, Z probe: not stopped



  • @BearcatTD said in Y axis only moves partial way across bed`:

    Y: at min stop,

    your y endstop is not working anymore.



  • It does the same thing with the new endstop. I'm going to make a new wire harness for the "Y's".
