Duet3 6HC, reference voltage for temperature sensors
-
On my 6HC mainboard all temperature values at 20°C are about 4°C too low (all the sensors are correctly configured with default values). The same sensors show the correct values on the Expansion Board 3HC (with the same parameters). It seems like the reference voltage on my 6HC board is wrong. Can this be checked? Can this possibly be adjusted?

@murmeltier yes, you can calibrate the thermistor inputs. See https://duet3d.dozuki.com/Wiki/Calibrating_thermistor_and_PT1000_readings

@droftarts Perfect, exactly what I was looking for. Worked great for both of my boards. I now have differences (among the sensors) of 0.5 ° C. With the fixed resistors it was only 0.1 ° C!
perfect thank you!
