// Using a sensor like the MMU2S
/**
* MMU Extruder Sensor
* Add support for Prusa IR Sensor (or other) to detect that filament reach the extruder to make loading filament more reliable
* If your extruder is equipped with a filament sensor located less than 38mm from the gears you can use this feature
* During loading to the extruder, the sensor will stop the loading command when he's triggered and make a last move to load filament to the gears
* If no filament is detected, MMU2 will make more loading attemps, if finally no filament is detected, the printer will enter in runout state
