What happened?

The printer is showing the message "Check the print head thermistor wiring for possible damage."

Error name: Hotend Maxtemp error

Error code: #26206 (MK4S) #13206 (MK4)  # 27206 (MK3.9S) #21206 (MK3.9) #28206 (MK3.5S) #23206 (MK3.5) #31206 (CORE One)

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.

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.

Getting this error after likely a static shock. Replaced hotend with a known good one and error persisted. Is the next step to replace the love board?
