Print job does not start

Hi everybody

When I start a printing job the printer after heating goes to a point and wait for the filament to be exchanged and it stays at "Print paused". After filament is chaged and extruded I do "Print resume" and it restart the same procedure, that is goes to the inicial point and wait for the filament be exchaged.

Can someone help me? What is the problem? is it a bug of Marlin 1.1.8?

It sounds like you are having problems with your filament out sensor.

#define FILAMENT_RUNOUT_SENSOR

First off do you have a filament out sensor. If not disable the above line.

If you have a filament runout sensor you may have it connect incorrectly or configured incorrectly.
My filament filament runout sensor needed to be inverted

#define FIL_RUNOUT_INVERTING true
and I needed to assign a pin for it to operate correctly in "pins_RAMPS.h"

Robert thanks for your answer.
Nevertheless if I change the status to true it simple do not start pre print procedures.

I saw your answer to another where you say you connected the filament runout to X Max and did some changes on the firmware like that:

Pins.Ramps.h
//#ifndef X_MAX_PIN
//#define X_MAX_PIN 2 // This is my X-Max pin, you should yours
//#endif

// define X_MAX_PIN 2 for the filament runout sensor.
#define FIL_RUNOUT_PIN 2

Configuration_adv.h
#define FILAMENT_CHANGE_FEATURE

I have two questions about this

1 - My configuration_adv.h does not have #define FILAMENT_CHANGE_FEATURE

2 - On Pins.Ramps.h you create the line #define FIL_RUNOUT_PIN 2?

I had my runout sensor connected to servo connection and I would like to try your way.

Can you pls explaine the procedure for Marlin 1.1.8?

Thanks for your cooperation

I am using Marlin 1.1.5 though the same procedure should apply to Marlin 1.1.8

I have never upgraded to Marlin 1.1.8 have help others upgrade to Marlin 1.1.8

You will have to adjust the Pins for your controller, my controller is a Ramps 1.3/1.4 compatible controller.
