What happened?
Your printer is showing the message "Check the chamber thermistor wiring for possible damage."
Error name: Chamber_mintemp
Error Number: #31215
This error happens when the temperature measured by the chamber thermistor has dropped suddenly.
How to fix it?
This error is usually caused by the chamber thermistor. It is located on the fan grid on the back panel of the CORE One. Check if the thermistor is in place and if there is no damage along the cable length. Move the cable by hand and check if the temperature fluctuates over 5ºC at a time.
Access the xBuddy extension board and check the thermistor cable connector.
If the thermistor is damaged, it needs to be replaced.
