Better version on how to tell if your printer runaway sensor is working…

This is the better version on how to tell if the runaway sensor is working. 1). Unscrew the back of the printer’s extraordinary system so you remove the cover 2). Carefully take out the thermometer (that is the thing sticking in the heat box) 3). Turn on your printer. If it says thermal runaway then that means that it works if not you can go to Creality’s download site and download the latest marlin. And last but not least you turn off the printer and put the thermometer back in.
