You can not depend on electronics or circuits to be the fire shut off. The only really approved way and its UL listed is a thermal fuse mounted to sense over temperature and positively break by mechanical means, the power to the heater. Think toaster, coffee pot, space heaters and the like. A UL lis...

At one time I had another very well known brand, also made in USA. The build quality of the M2/M3 gives it a advantage over the other brands. It just works. The...

If I had a concern and I do not because my printing is done away from any combustibles I would wire in a Thermal fuse in series with the extruder heater. Non- resettable one time. Oops I see insta already suggested. It could be lower rated than the heater temp, just mounted close by and not on it. T...
