Hi, is it possible to correct for a temperature offset between the hotend sensor reading and the actual temperature within the nozzle via gcode? In this case I would need to give it a slope of 2.75 minus 54°C (y=x*2.75-54) to correct a reading of 100°C for an actual temperature of 218,5°C (yes that is huge but it cannot be helped hardware wise currently).
thx!
