@Anglu said in Temperature Difference of around 25 deg C:
Unfortunately, I have noticed that my printer is printing around 25 degrees C hotter than it should be.
How have you determined that? What filament did you use for your test print, and what temperatures did you select?
You can check the accuracy of the Duet temperature measurement by connecting a fixed resistor in place of the thermistor. It's possible to identify and correct for ADC errors in this way. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Temperature_connecting_thermistors_PT1000#manual-calibration. However, any ADC error should be much less than 25C.
