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