Switching one extruder sensor to a fake temp. sensor without reuploading the firmware

Is it possible to switch an extruder to a fake temp. sensor (always returning ~25°C) without reuploading the firmware?
So you could remove one extruder from a dual extruder printer when you want to print with a single one.


  • No that is not possible. But you could replace the thermistor with a 100k resistor shorting the 2 wires, that also gives 25°C
