+ * High Temperature Thermistor Support

+ * preheating process, which will trigger a min_temp_error as a safety measure
+ * and force stop everything.
+ * To circumvent this limitation, we allow for a preheat time (during which,
+ * min_temp_error won't be triggered) and add a min_temp buffer to handle
+ * aberrant readings.
+ *
+ * If you want to enable this feature for your hotend thermistor(s)
