"FILAMENT_RUNOUT_SENSOR" do not work.

I can't speak english. I used google translate.

marlin 1.1.0 rc3.... Configuration.h

//===========================================================================
//========================= Filament Runout Sensor ==========================
//===========================================================================
#define FILAMENT_RUNOUT_SENSOR // Uncomment for defining a filament runout sensor such as a mechanical or opto endstop to check the existence of filament
                                 // In RAMPS uses servo pin 2. Can be changed in pins file. For other boards pin definition should be made.
                                 // It is assumed that when logic high = filament available
                                 //                    when logic  low = filament ran out
#if ENABLED(FILAMENT_RUNOUT_SENSOR)
  const bool FIL_RUNOUT_INVERTING = true;  // Should be uncommented and true or false should assigned
  #define ENDSTOPPULLUP_FIL_RUNOUT // Uncomment to use internal pullup for filament runout pins if the sensor is defined.
  #define FILAMENT_RUNOUT_SCRIPT "M600"
#endif

I use microswitch.

I try D4, D5, D6 and D11. and.

const bool FIL_RUNOUT_INVERTING = false;  // Should be uncommented and true or false should assigned

and.

//  #define ENDSTOPPULLUP_FIL_RUNOUT // Uncomment to use internal pullup for filament runout pins if the sensor is defined.

when I microswitch on or off...does not happen anything.

I used marlin 1.0.6 and D42 ( http://forums.reprap.org/read.php?1,297350 ) It was work well.

Are you using a RAMPS board?

Did you notice the comment:

// In RAMPS uses servo pin 2. Can be changed in pins file. For other boards pin definition should be made.

[KiteLab]

If it's only a simple switch

#define ENDSTOPPULLUP_FIL_RUNOUT

makes sense in about half of the possible cases.

to. Roxy-3DPrintBoard Thank you. I using Ramps 1.4 servo pin 2 = D6 I try D6 servo pin 1,3,4 = D11, D5, D4 I try also. but not work.

to KiteLab sorry. I can't understand what you say. please tell me again.

[Roxy-3D]

@famtory You need to KNOW what pin you have things connected. Do you have a volt meter or a logic probe? If you connect it to your pin, you should be able to use M42 P? S0 followed by a M42 P? S1 to see the pin toggle.

When you know a pin number you can connect to and toggle, we can help you more.

My printer use coreXY. so D2(axis X max pin) not use.

Mod pins_RAMPS_13.h

#if ENABLED(FILAMENT_RUNOUT_SENSOR)
  // define digital pin 4 for the filament runout sensor. Use the RAMPS 1.4 digital input 4 on the servos connector
//  #define FILRUNOUT_PIN     4 
  #define FILRUNOUT_PIN     2
#endif

I connect sensor on D2

Now... It work!

Thank you.

Hi, @famtory!, @KiteLab! These days, I meet the same problem. I tried some methods just like change the pin for filament runout to Z_endstop_max or other unused pins, and modify the codes relating to filament runout. Unfortunately, I failed. The hardwares I used are arduino mege 2560 + remp 1.4. Instead of using SD card printing method, I use PC. To be exact, I did not buy any components about SD Card. So, how you solve your problem? Are there any details I missed? Thank you!

@Blue-Marlin Hi, Blue-Marlin. Yes, I met this issue. For solving it, I also used an unused pin D4. I just use a PC to print my model not SD card. The following codes are what I used.

Configuration.h

//========================= Filament Runout Sensor ==========================
//================================================== =========================
#define FILAMENT_RUNOUT_SENSOR // Uncomment for defining a filament runout sensor such as a mechanical or opto endstop to check the existence of filament
// In RAMPS uses servo pin 2. Can be changed in pins file. For other boards pin definition should be made.
// It is assumed that when logic high = filament available
// when logic low = filament ran out
#if ENABLED(FILAMENT_RUNOUT_SENSOR)
const bool FIL_RUNOUT_INVERTING = true; // Should be uncommented and true or false should assigned
#define ENDSTOPPULLUP_FIL_RUNOUT // Uncomment to use internal pullup for filament runout pins if the sensor is defined.
#define FILAMENT_RUNOUT_SCRIPT "M600"
#endif

pin_RAMPS_13.h

#if ENABLED(FILAMENT_RUNOUT_SENSOR)
// define digital pin 4 for the filament runout sensor. Use the RAMPS 1.4 digital input 4 on the servos connector
#define FILRUNOUT_PIN 4
#endif

Marlin_main.cpp

void setup_filrunoutpin() {
#if HAS_FILRUNOUT
pinMode(FILRUNOUT_PIN, INPUT);
#if ENABLED(ENDSTOPPULLUP_FIL_RUNOUT)
WRITE(FILRUNOUT_PIN, HIGH);
#endif
#endif
}

Marlin_main.cpp

void manage_inactivity(bool ignore_stepper_queue/*=false*/) function.

#if HAS_FILRUNOUT
// if (IS_SD_PRINTING && !(READ(FILRUNOUT_PIN) ^ FIL_RUNOUT_INVERTING))
if ((READ(FILRUNOUT_PIN) ^ FIL_RUNOUT_INVERTING))
filrunout();
#endif

How do you think these codes? Am I right or wrong? Thank you!

[Blue-Marlin]

If it works for you it's ok, if not not. The main problem seems to be to find a unused pin. Alone in the provided standard configuration D4 can be used by the FILRUNOUT_PIN, the FAN_PIN (for EEB) and SERVO3_PIN. If using D2 pay attention on it is not used for x_max. And so on.

[373996214]

@Blue-Marlin Thank you! Today, I changed D4 to Z_Max_endstop. Although I did this, the same result happened. How do you think this problem? In some forums (http://forums.reprap.org/read.php?1,599640,606852), someone said the printing method, SD or host, has an influnce on filament runout function. I dont it is real or not. Anyway, Ill try what you said.

[yucelll]

hello. I try D4 but not working.

[373996214]

@yucelll I tried both D4 and Z_Max_endstop, the same results I got, the printer still works. Do you try other pins and how is the result?
