      Hi,

      I've been working on a rotating filament sensor (with a magnet + hal effect sensor).
      I've gotten to the point where it seems to be working well and reliable (3 weeks now, on a printer running marlin).
      I'm using rubber X-seals to ensure good contact with the filament without adding too much resistance.

      Do any of you think it's an interesting device to have ?

      It detects both when the filament spool is empty and when the print head is clogged.
      I do "a lot" of 3d printing and these 2 cases seem to account for +90% of my failed prints (I often print flame resistant abs and this can clog at times)

      I've made a small video, https://youtu.be/DCe-7jBzin0

      I posted this on the reprap forum last week but there was zero response 😞

      thx
      Bram

        I think it's a pretty good idea.

        How does it compare to THIS?

          I tried buying the duet one last year but was unable to find it at that time.
          It uses some special parts if I'm not mistaken, for my design
          you need 4 flanged bearings, 2 X-seal rubbers, a couple of washers, a magnet and a hal effect sensor, on my board the sensor is connected directly to the board and works as on/off switch, I think this is possible on a duet board as well.
