Ender 3 v2 AutoHome / Z Axis end switch issue

  • Just got my Ender 3 v2 assembled today. Found that autohoming moves the X and Y axis as it's supposed to but the Z access only moves up a tiny bit. I believe it thinks the Z end switch is engaged. Swapped the Z end switch with the X end switch, made no change. Swapped the Z and X end switch cables on the board and still made no difference (except I have to press the end switch in the Z position while X is homing since they're swapped). So both Z and X end switches and cable are good but the Z axis still does not autohome. Seems to me an issue with the board. Also flashed the firmware though it was already on the newest version.
    Any ideas? Did I just get a printer with a bad board and need to return it?

  • @wish2snowboard Hello, the same problem, I found an existing solution in ender3 v2.

  • I got it! All I had to do was:

    • turn off the printer
    • unplug it from power
    • unplug both z access plugs (1 for the motor 1 for the stopper)
    • plug them both back in firmly
    • plug power back in and turn it on

    No idea what it was thinking previously but hopefully that helps!

  • I just set up an Ender 3 yesterday and I'm having this exact issue! Autohome just keeps moving up a little bit on the z axis each time. Any chance you solved it? Or had to return it and get another?
