That error indicates that the extruder is trying to heat up, and the thermistor isn’t showing a temperature increase. The shutdown is thermal runaway protection.
Thanks. Will try heat gun. Im using a CHC - (ceramic heating core) though and thermistor is inside it. Also, the hotend does not even heat up. I checked the wire connectivity via tester and is ok. Im suspecting that the mosfet of the hotend might have been broken. With this, is using the heatbed terminal to the hotend an option that can be tried? Im using skr mini e3 v3
Make sure that you change your printer.cfg so that the hotend thermistor as the heated bed temperature sensor (you don’t need to rewire the thermistors, they’re there and ready to be used).
I recommend that you only set a temperature of 50C to test the heated bed driver.
