So I have an issue where my nozzle thermistor reads around 120°C. Heating the nozzle works and reports back a temperature change. I tried to check the voltage on therm1 (nozzle) and therm2 (heated bed). Therm2 reads 5 volts and therm 1 reads 2 volts. I guess this is not correct as it should be 5 volts on both?
So what are my options here? How do I proceed and solve this issue?
Steps I’ve taken are:
- Flash a new firmware.
- Check the wiring.
- PID autotune
