#define BED_CHECK_INTERVAL 5000 //ms
//// Experimental watchdog and minimal temp
// The watchdog 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
/// CURRENTLY NOT IMPLEMENTED AND UNUSEABLE
//#define WATCHPERIOD 5000 //5 seconds
//// Heating sanity check:
// 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
//#define WATCHPERIOD 20000 //20 seconds
// Actual temperature must be close to target for this long before M109 returns success
//#define TEMP_RESIDENCY_TIME 20 // (seconds)
