Filament runout echo:unknown command: M412
February 16, 2019 03:45PM
I have set in configuration.h
#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 true // set to true to invert the logic of the sensor.
//#define FIL_RUNOUT_PULLUP // Use internal pullup for filament runout pins.
#define FILAMENT_RUNOUT_SCRIPT "M600"
#endif

and in pins_rumba.h

// Runout sensors
#define FIL_RUNOUT_PIN 14
#define FIL_RUNOUT2_PIN 15

I am getting echo:unknown command: M412

Any ideas?

I believe that this Command is only valid in Marlin 2 as shown in the attached photo. ("</>2.0.0") in green

It allows you to enable or disable the Filament run-out sensor and continue printing without a filament run-out sensor.

M412 works perfect in My Marlin 2.0.x BugFix which has been installed in both my 3D Printers.

Thanks for the quick reply.
I am new to Marlin and 3d printers in general and and have nearly finished completing my cubex duo/rumba build. I am utilising the built in filament detector on the duo.
Runout Sensors is defined in the 1.1.9 Configuration.h file. I am surprised it would be defined but not supported.

/**
* Filament Runout Sensors
* Mechanical or opto endstops are used to check for the presence of filament.
*
* RAMPS-based boards use SERVO3_PIN for the first runout sensor.
* For other boards you may need to define FIL_RUNOUT_PIN, FIL_RUNOUT2_PIN, etc.
* By default the firmware assumes HIGH=FILAMENT PRESENT.
*/
#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 true // set to true to invert the logic of the sensor.
//#define FIL_RUNOUT_PULLUP // Use internal pullup for filament runout pins.
#define FILAMENT_RUNOUT_SCRIPT "M600"
#endif

I avoided going with 2 because I was worried about bugs (if there are any) confusing my learning curve.

Is 2 ready to use? Or should I wait and just not use the runout sensors for now?

Will my 1.1.9 configuration file be usable in 2 or will it need a lot of work?

I couldn't see any attached photo btw.

Mostly the bugs are in the 32bit controller firmware, as I am still using a 16bit controller I do not have to worry about any 32bit errors.

They are maintaining a list of the controllers that are still having problems Here and my RAMPS, compatible is good to go so I went...

Good to know. My Rumba is basically a ramps board so I should be good to go.

I like it, it has many features that make it better, an still learning the features.

#define S_CURVE_ACCELERATION

#define JUNCTION_DEVIATION // in lieu of XYZ Jerk

#define RESTORE_LEVELING_AFTER_G28

#define PARK_HEAD_ON_PAUSE // Normally when I paused it stopped at the current location and melted the model, now stops and moves to a park location

I installed Marlin 2bf and am back up and running with 'runout sensors On displayed on the LCD. Thanks for the assistance.
