-This is a feature to protect your printer from burn up in flames if it has
-a thermistor coming off place (this happened to a friend of mine recently and
-motivated me writing this feature).
 
-The issue: If a thermistor come off, it will read a lower temperature than actual.
-The system will turn the heater on forever, burning up the filament and anything
-else around.
-
-After the temperature reaches the target for the first time, this feature will
-start measuring for how long the current temperature stays below the target
-minus _HYSTERESIS (set_temperature - THERMAL_RUNAWAY_PROTECTION_HYSTERESIS).
-
-If it stays longer than _PERIOD, it means the thermistor temperature
-cannot catch up with the target, so something *may be* wrong. Then, to be on the
-safe side, the system will he halt.
-
-Bear in mind the count down will just start AFTER the first time the
-thermistor temperature is over the target, so you will have no problem if
-your extruder heater takes 2 minutes to hit the target on heating.

+ *
+ * The issue: If a thermistor falls out or a temperature sensor fails,
+ * Marlin can no longer sense the actual temperature. Since a disconnected
+ * thermistor reads as a low temperature, the firmware will keep the heater on.
+ *
+ * The solution: Once the temperature reaches the target, start observing.
+ * If the temperature stays too far below the target (hysteresis) for too long,
+ * the firmware will halt as a safety precaution.
+ *
+ * Note that because the countdown starts only AFTER the temperature reaches
+ * the target, this will not catch a thermistor that is already disconnected
+ * when the print starts!
