Error name: Hotend Maxtemp error
Error code: #13206 (MK4) #21206 (MK3.9)
This error is shown when the printer's nozzle temperature goes above 305 ºC at any point. This is a safety feature to prevent printer damage. The print will be stopped and the printer will cool down.
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.
Make sure that the Loveboard main cable is correctly connected to the xBuddy board.
