/**
* Redundant Temperature Sensor (TEMP_SENSOR_REDUNDANT)
*
* Use a temp sensor as a redundant sensor for another reading. Select an unused temperature sensor, and another
* sensor you'd like it to be redundant for. If the two thermistors differ by TEMP_SENSOR_REDUNDANT_MAX_DIFF (°C),
* the print will be aborted. Whichever sensor is selected will have its normal functions disabled; i.e. selecting
* the Bed sensor (-1) will disable bed heating/monitoring.
*
* Use the following to select temp sensors:
* -5 : Cooler
* -4 : Probe
* -3 : not used
* -2 : Chamber
* -1 : Bed
* 0-7 : E0 through E7
