Thermal runaway #396
Description
Hoping someone can point me in the right direction.. I just finished the install of OpenNeptune on my neptune 4 max and was working on calibration. I ran the PID_TUNE_EXTRUDER and then had a thermal runaway shutdown. There was smoke and everything coming off the hotend.I can see that it was reading the temperature can anyone tell me why this happened or how to fix it?
