Hey, my printer recently stopped working saying the filament ran out even though it was still in for use. I checked the sensor and sure enough it was worn down, so I replaced it. But now I’m getting the same message even though I just replaced the sensor and all the wires are connected back to the sensor and printer. If it helps any, I use a longer 5 pro.
What kind of sensor is it? If it’s a switch type, you could try bypassing it and see if your printer detects open circuit/closed circuit correctly. If it doesn’t check the wiring.
