I have a problem with my ender 3 but i have no clue what might be wrong. Yesterday my printer stopped running during a print (I was printing PLA at 200 degrees). I went to my printer and it showed the outage recovery screen when i didnt have a power outage. When I pressed resume print, the bed heated up fine, but when it was time for the extruder to heat, my printer beeped for a few seconds and then returned to the outage recovery screen. My extruder temp showed -14 degrees at that time when the temperature should have been around 22. My printer is connected to a surge protected outlet.

It seems like you may be facing an issue with your 3D printer. Here are a few potential troubleshooting steps you can try:

  1. Double-check the connections: Ensure that all the cables and connectors are properly attached to their respective ports. Sometimes loose connections can cause communication errors between the printer and the controller.

  2. Check the thermistor and heater cartridge: The issue could be related to a faulty thermistor or the heater cartridge for the extruder. Inspect the wiring and make sure they are firmly connected. It's also a good idea to measure the resistance of the cartridge and the thermistor if you have a multimeter.

  3. Update or reinstall firmware: There are instances where firmware bugs can cause unexpected behavior. Try updating the firmware to the latest version or reinstalling it to rule out any software-related issues.

  4. Inspect the power supply: Although you mentioned the printer is connected to a surge protected outlet, it's worth examining ...

The -14 degrees thing makes me think it must be a broken thermistor. But I'm not sure why that's bringing up the power outage screen.

Yeah a few people i asked said its probably the thermistor

But one person said it might be a shorted mainboard. I dont think its that because the bed heats up
