The MOSFET on my KP3S-3.0 was damaged in short mode. At that time, the runaway heater Bed rose to 116℃, but since the max temp value was set at 130℃, power continued to be supplied to the burning MOSFET without triggering an emergency stop.
Considering individual differences in thermometers and usage environments, it is recommended to lower the max temp to 105℃. It is also necessary to add a comment in the code that if the max temp is set above 105℃, there is a possibility that an emergency stop may not be triggered.

The max temp of the Extruder is safe at 300℃.
