Extruder inspection

This error is usually caused by the hotend thermistor.

Access the LoveBoard. Check if the thermistor is connected correctly and if there is no damage along the cable length.

If you have a multimeter, it is possible to check the resistance of the cables to verify if they are damaged. For that, use our Multimeter usage guide.

xBuddy board inspection
