  • I’m assuming this is a stock motherboard with motor drivers soldered directly to the board without daughter boards and sockets?

    Without digging in deeper it sounds like your motor driver is dead. If it’s a stock board you need to replace the entire thing. If you don’t already own a soldering iron and multi-meter then we can skip past the fantasy that you could replace a surface mount stepper driver yourself.

    Good news is replacement boards are very cheap. There are great replacement options from both Creality and BigTreeTech. I would go with one of the drop in options, BTT will have E3 in the name. If you’re feeling more adventurous and don’t mind putting in more time and effort you can get a non-drop in board that has sockets instead of hard wired stepper drivers. That would allow you to drop in a replacement driver if this happens again. However it’s going to take significantly more effort, especially on the software side, before you get your printer running again.

    Also, my advice is if you’re going to own a complex hobby electronics device like an Ender 3 you need to own your own multi meter.
