Marlin: set the MKS_PWC with MKS_GEN_L

Question

I have recently bought a MKS_PWC v3 power management system to work with my 3d printer, that runs a MKS_GEN_L v1.0 motherboard.

I flashed and configured previously the Marlin v2.1-bugfix branch to work with the 3d printer. Everything works fine, except the newly bought MKS_PWC (I connected every pin except the TFT display, which would be the RepRap Discount controller. The signal pin never stays high. The D11 pin being used by my bltouch sensor, I tried to set the D6 pin for the PWC control (in configuration.h).

#define PS_ON_PIN 6

I tried to define the same pins in pins_RAMPS.h, without further success.

There is my configuration regarding the power supply


#define PSU_CONTROL
//#define PSU_NAME "Power Supply"

#if ENABLED(PSU_CONTROL)
  #define MKS_PWC                 // Using the MKS PWC add-on
  //#define PS_OFF_CONFIRM          // Confirm dialog when power off
  //#define PS_OFF_SOUND            // Beep 1s when power off
  #define PSU_ACTIVE_STATE HIGH      // Set 'LOW' for ATX, 'HIGH' for X-Box

  //#define PSU_DEFAULT_OFF               // Keep power off until enabled directly with M80
  //#define PSU_POWERUP_DELAY      250    // (ms) Delay for the PSU to warm up to full power
  //#define LED_POWEROFF_TIMEOUT 10000    // (ms) Turn off LEDs after power-off, with this amount of delay

  //#define POWER_OFF_TIMER               // Enable M81 D<seconds> to power off after a delay
  #define POWER_OFF_WAIT_FOR_COOLDOWN   // Enable M81 S to power off only after cooldown

  //#define PSU_POWERUP_GCODE  "M355 S1"  // G-code to run after power-on (e.g., case light on)
  //#define PSU_POWEROFF_GCODE "M355 S0"  // G-code to run before power-off (e.g., case light off)

  //#define AUTO_POWER_CONTROL      // Enable automatic control of the PS_ON pin
  #if ENABLED(AUTO_POWER_CONTROL)
    #define AUTO_POWER_FANS         // Turn on PSU if fans need power
    #define AUTO_POWER_E_FANS
    #define AUTO_POWER_CONTROLLERFAN
    #define AUTO_POWER_CHAMBER_FAN
    #define AUTO_POWER_COOLER_FAN
    #define POWER_TIMEOUT              30 // (s) Turn off power if the machine is idle for this duration
    //#define POWER_OFF_DELAY          60 // (s) Delay of poweroff after M81 command. Useful to let fans run for extra time.
  #endif
  #if EITHER(AUTO_POWER_CONTROL, POWER_OFF_WAIT_FOR_COOLDOWN)
    #define AUTO_POWER_E_TEMP        50 // (°C) PSU on if any extruder is over this temperature
    //#define AUTO_POWER_CHAMBER_TEMP  30 // (°C) PSU on if the chamber is over this temperature
    //#define AUTO_POWER_COOLER_TEMP   26 // (°C) PSU on if the cooler is over this temperature
  #endif
#endif

Also, if I put the PWC signal pin on a +5V, the printer stays on, so my problem really is that no high voltage gets to the signal pin of the PWC chip.

I have 2 servos defined, in case it matters.

#define NUM_SERVOS 2 // Note: Servo index starts with 0 for M280-M282 commands
#define SERVO_DELAY { 300, 300 }

What am I missing to make it work?
