      I'm more or less a novice when it comes to circuit design, but would it be feasible to add something along the lines of a NO switch to the mount for the spring loaded wheel (or elsewhere) so it can detect the presence and not just the motion of the filament? My thought is that printer sees an open circuit and recognizes no filament and when the circuit closes, it looks for the motion of the wheel to monitor feed.

      Pardon my ignorance of the finer working of the firmware and circuitry.

        Yes, the hardware already has that facility, so does the firmware on the Duet. But I need to update the filament sensor firmware to support it.
