3D Guardian is an ultimate 3D printer fire prevention device, with some extras.
The primary function of 3D Guardian is to constantly monitor the printer's environment, and to shut it down (sounding an alarm) if the environment moves beyond the trained range. In addition to the traditional sensors (temperature, smoke, CO), it has a unique feature - a heated bed resistance sensor, which constantly monitors the resistance (voltage and current) of the heated bed wiring. Problems with this wiring
