Nozzle temperature. Lowperature.


Topic starter

I have the Ender 3 V2 on Ender-3 V2-Marlin-2.0.1-HW-4.2.2-mainboard-V1.1.2-Compatible with BLTouch and filament detection.

I keep receiving "Nozzle is to lowperature." The nozzle will not go over 212C. I have tried different firmware and receive a thermal runaway error. I also tested the connection to the motherboard of the thermistor, which is good. I OHMed the thermistor and at the motherboard I did not get a reading. I am thinking it is the thermistor but why would my temperature go to 212C just fine. I OHMed the wires themselves going to the thermistor and the resistance was almost zero. I am not sure it is the thermistor.

The thermistor is monitoring the temperature, the temperature is normal because the heating tube is working properly. But the motherboard can not receive the correct temperature back will lead to such an error. The resistance value should be 100k, instead of almost 0.
