//// Experimental watchdog and minimal temp //// Heating sanity check:
// The watchdog waits for the watchperiod in milliseconds whenever an M104 or M109 increases the target temperature // This waits for the watchperiod in milliseconds whenever an M104 or M109 increases the target temperature
// If the temperature has not increased at the end of that period, the target temperature is set to zero. It can be reset with another M104/M109 // If the temperature has not increased at the end of that period, the target temperature is set to zero.
/// CURRENTLY NOT IMPLEMENTED AND UNUSEABLE // It can be reset with another M104/M109
