 * Filament runout sensor such as a mechanical or opto endstop to check the       *
 * existence of filament                                                          *
 * It is assumed that when logic high = filament available and when logic         *
 * low = filament run out                                                         *
 * Single extruder only at this point (extruder 0)                                *
 *                                                                                *
 * Uncomment FILAMENT_RUNOUT_SENSOR to enable this feature                        *
 * You also need to set FILRUNOUT_PIN in Configuration_pins.h                     *
