Ender 3 V2 stuck on Autohome/Motors unresponsive



  • Need some help. Setup my v2 last night and everything was going fine until the autohome part of the build.

    The extruder and bed do not move at all. Motors don't move on the X, Y, or Z axis. Auto Home runs forever and does not complete or move the extruder. Using the screen under the 'Prepare' section to move the extruder and the bed does not work either.

    I've tried updating the firmware and swapping the X and Y power cables. I was wondering if I should open it up and look at the motherboard? I wish they kept the 2 screw entry to the MB compartment from the pro. It's like 6 screws to get to the motherboard in a v2.

    Is there an official place to download firmware? The firmware update I tried broke my screen and I had to follow these instructions to fix the problem https://forum.creality.com/topic/94/ender-3-v2-black-screen?lang=en-US

    Fan works, belt tension seems fine, bed and extruded aren't stuck, the axis limiters also seem fine. I've double checked wire positions. Any pointers would be extremely helpful.

    Thanks!

  • @admin I had exactly the same problem. I hadn't tried my printer, I just built it and then flashed it to 1.3.1. When I powered it up none of the motors worked. They all locked up for 2-3 seconds and then released. That was all it did. The bed heated, but nothing else worked. To keep it short, I flashhed it down to 1.0.2 and everything worked. Suffice it to say that I'm a very happy camper! I hope that this works for those of you with the same problem.
    My printer is the Ender 3 v2. The original flash was 1.0.1.

    1. Please check whether the power supply voltage is adjusted to the local voltage
    2. Refresh the motherboard firmware
