Hello everyone,
I have an AIO II v3.2 running a createbot max 3D printer. The printer was working great with a 24V 50W hot end. The hot end suddenly stopped heating a few days ago, only the green led next to the mosfet flickers for a while and then switches off. I tried flashing the firmware on it and instead of testing it with the hot end again, I tried it with the hot bed and hot bed thermistor. It worked perfectly fine but the moment I switched it back to the hot end and hot end thermistor, it would switch off and stop heating.
I would like to have your thoughts on this issue. Also will the microcontroller switch off the mosfet automatically if it senses a short in the hot end ?
