How to fix it?

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

Make sure that the Loveboard main cable is correctly connected to the xBuddy board.
