Does anyone know if there is a chart of what the thermistor voltage should be relative to temp? From what I have been able to check, my actual nozzle temp does not agree with what is shown on the screen. I have changed the thermistor twice with no change in readings. Trying to decipher if there is a problem with the main circuit board. Thanks
