So...thermistors. I just finished the last steps of calibrating my custom corexy 3d printer and then... I think the hotend thermistor is broken. When I turn the printer on the Full Graphic Smart Controller shows a min temp error. Any help would be greatly appreciated. Configuration.h is attached.

If you think your thermistor is broken, measure it with a multimeter for resistance.

What values should it display at room temperature? (I have a 100kohm thermistor)

A 100k thermistor should be 100k at 25C - that's why it is called a 100k thermistor.
