Nextruder Heatsink
The load cell is an integrated strain gauge bonded to the aluminum heatsink; mechanical drift occurs when parasitic torque from assembly fasteners or thermal expansion cycles causes the sensor's baseline resistance to shift. This shift prevents the firmware from accurately taring the sensor before probing, resulting in incorrect nozzle-to-bed offsets. Replacing the heatsink ensures a factory-calibrated sensing bridge free from mechanical deformation.
