[Help] My Ender 3 isn't powering the extruder motor. Do I need a new motherboard? - eviltoast

The extruder suddenly stopped working after I cleared a jam that caused it to grind.

  • I tried every combination of motor and cable to trace the problem. It seems the only fault is the extruder’s motherboard connector.

  • The motor is functional. I connected it to the XYZ motor cables and it spins on every one.

  • Nothing happened when I tried plugging the other axis cables into the extruder port on the motherboard.

  • Finally, I am comfortable using a multimeter and soldering iron, but don’t have immediate access to them.

I really appreciate any advice on this because I miss printing!

    I only brought it up because they brought up the soldering iron in their post. I could probably replace one of those surface mount drivers, but I also wouldn’t. Not when you can buy a whole board for $20usd.
