    Hello. I have a pusle type filament sensor. It is working ok while printinting, but I was wondering: can it be used to detect filament while it is being loaded? for example can it be used to detect if the filament is really beeing feed to the extruder or not while it is being loaded? Because I cant find any value to monitor

      @Tinchus I have NOT tried this, so, purely theoretical, but if your filament sensor is configured I think something like the following in your loading macro at whatever point you want to check status would give you what you want:

      if sensors.filamentMonitors[0].filamentPresent = true

      G-and-another-thing

        @Maestro There is no "filamentpresent" object in the object model of a filament monitor configured as pulse sensor, am I right? Cant find that object.

          @Tinchus that's correct. The filamentPresent status is only provided for filament monitors that have a switch to detect presence of filament, separate from detecting motion of filament. Lack of motion does not necessarily mean that there is no filament, it can mean that the hot end is jammed.

            @dc42 Thnaks. Can you tell me actual state of development of pulse type of filament monitor ? Im still having very strange issues with pulse filaments sensors. Even when changed to diferent brands off encoders, error is always the same

              @Tinchus pulse type filament sensors are fully developed and supported in RRF. But you are asking for filament presence sensors, which can be used in addition to/combination with pulse rate sensors.

                @oliof No. I have other errors reported on other posts, oldonw. Sorry to bring this here. Should I create a new one?

                  @Tinchus I'm just a guy on this forum knowing tons of people that run pulse sensors, your "No" attitude isn't helping.

                  I won't stop you from opening another thread, best of success with figuring it out!

                    @oliof oliof, english is no my mother language, if I wrote something that communicated a "no attitude" as you describe, I apologize. My intention was not report error on a post not meant for that, that is why didnt went on fully details about the error and asked for the proper way to report it

                    Following your reaction I guess I should have done it here: the error on pulse filament sensor Im obsrving from som time, if that even when starting a print, I get and almost inmediate error from firmware, filament-error.g is triggered, but when requesting the calibration data, i get a "no calibration data" message menaing the sensor still has not gotten enough info to make such calibration, so how it is possible that firmware "detected" a filament error"?
                    Im running 3.4.6, duet3 SBC
