this is the firmware setting for FILAMENT_RUNOUT_SENSOR
#define FILAMENT_RUNOUT_SENSOR
#if ENABLED(FILAMENT_RUNOUT_SENSOR)
#define NUM_RUNOUT_SENSORS 1 // Number of sensors, up to one per extruder. Define a FIL_RUNOUT#_PIN for each.
#define FIL_RUNOUT_INVERTING FALSE // Set to true to invert the logic of the sensor.
#define FIL_RUNOUT_PULLUP // Use internal pullup for filament runout pins.
//#define FIL_RUNOUT_PULLDOWN // Use internal pulldown for filament runout pins.
// Set one or more commands to execute on filament runout.
// (After 'M412 H' Marlin will ask the host to handle the process.)
#define FILAMENT_RUNOUT_SCRIPT "M600"
the firmware should respond with the instructions set in advanced pause and nozzle park feature:
#define ADVANCED_PAUSE_FEATURE
#if ENABLED(ADVANCED_PAUSE_FEATURE)
#define PAUSE_PARK_RETRACT_FEEDRATE 60 // (mm/s) Initial retract feedrate.
#define PAUSE_PARK_RETRACT_LENGTH 2 // (mm) Initial retract.
// This short retract is done immediately, before parking the nozzle.
#define FILAMENT_CHANGE_UNLOAD_FEEDRATE 10 // (mm/s) Unload filament feedrate. This can be pretty fast.
#define FILAMENT_CHANGE_UNLOAD_ACCEL 25 // (mm/s
2) Lower acceleration may allow a faster feedrate.
#define FILAMENT_CHANGE_UNLOAD_LENGTH 100 // (mm) The length of filament for a complete unload.
// For Bowden, the full length of the tube and nozzle.
// For direct drive, the full length of the nozzle.
// Set to 0 for manual unloading.
#define FILAMENT_CHANGE_SLOW_LOAD_FEEDRATE 6 // (mm/s) Slow move when starting load.
#define FILAMENT_CHANGE_SLOW_LOAD_LENGTH 0 // (mm) Slow length, to allow time to insert material.
// 0 to disable start loading and skip to fast load only
#define FILAMENT_CHANGE_FAST_LOAD_FEEDRATE 6 // (mm/s) Load filament feedrate. This can be pretty fast.
#define FILAMENT_CHANGE_FAST_LOAD_ACCEL 25 // (mm/s
2) Lower acceleration may allow a faster feedrate.
#define FILAMENT_CHANGE_FAST_LOAD_LENGTH 0 // (mm) Load length of filament, from extruder gear to nozzle.
// For Bowden, the full length of the tube and nozzle.
// For direct drive, the full length of the nozzle.
//#define ADVANCED_PAUSE_CONTINUOUS_PURGE // Purge continuously up to the purge length until interrupted.
#define ADVANCED_PAUSE_PURGE_FEEDRATE 3 // (mm/s) Extrude feedrate (after loading). Should be slower than load feedrate.
#define ADVANCED_PAUSE_PURGE_LENGTH 50 // (mm) Length to extrude after loading.
// Set to 0 for manual extrusion.
// Filament can be extruded repeatedly from the Filament Change menu
// until extrusion is consistent, and to purge old filament.
#define ADVANCED_PAUSE_RESUME_PRIME 0 // (mm) Extra distance to prime nozzle after returning from park.
//#define ADVANCED_PAUSE_FANS_PAUSE // Turn off print-cooling fans while the machine is paused.
// Filament Unload does a Retract, Delay, and Purge first:
#define FILAMENT_UNLOAD_RETRACT_LENGTH 13 // (mm) Unload initial retract length.
#define FILAMENT_UNLOAD_DELAY 5000 // (ms) Delay for the filament to cool after retract.
#define FILAMENT_UNLOAD_PURGE_LENGTH 8 // (mm) An unretract is done, then this length is purged.
#define PAUSE_PARK_NOZZLE_TIMEOUT 45 // (seconds) Time limit before the nozzle is turned off for safety.
#define FILAMENT_CHANGE_ALERT_BEEPS 10 // Number of alert beeps to play when a response is needed.
#define PAUSE_PARK_NO_STEPPER_TIMEOUT // Enable for XYZ steppers to stay powered on during filament change.
//#define PARK_HEAD_ON_PAUSE // Park the nozzle during pause and filament change.
//#define HOME_BEFORE_FILAMENT_CHANGE // Ensure homing has been completed prior to parking for filament change
//#define FILAMENT_LOAD_UNLOAD_GCODES // Add M701/M702 Load/Unload G-codes, plus Load/Unload in the LCD Prepare menu.
//#define FILAMENT_UNLOAD_ALL_EXTRUDERS // Allow M702 to unload all extruders above a minimum target temp (as set by M302)

when i send m600 from host, it work. when i try whit sensor dont work.
