Blank screen on power up ender 3 v2



  • Re: Blank LCD Screen Ender-3 v2
    Ok, discovered if one leaves the usb plugged in to the pc AND powers off the printer And then notices that with the power off the lcd panel is still lit AND you touch anything on the control panel, one will lock up the printer and it won't boot.

    So, simply unplug the usb cable and power up the printer and all should be fine. The thing goes batsh*t crazy if left with USB plugged in. In the process of working this out, I made a new firmware as well. That didn't help..

    Simply unplugging USB did...

  • You have to block the power pin on the usb cable. I purchased one adapter to do this or you can use electric tape.
