      I've been getting some....very odd results when trying to configure the magnetic filament sensor. Any ideas?

      The min/max are always at these results, no matter how much prints

      Duet3D rotating magnet filament monitor v3 on pin 121.io1.in, disabled, sensitivity 28.80mm/rev, allow 60% to 160%, check every 3.0mm, version 3, mag 132 agc 78, measured sensitivity infmm/rec, min 2147483647% max 2147483647% over 99.1mm

        @nightlonk42 which version of RepRapFirmware are you using, and on which Duet?

        My guess is that filament motion is not causing the magnet to rotate.

          @nightlonk42 with the sensor assembled you should be able to feel the magnet rotates freely when manually running some filament through (by hand to feel the force). if you make a small dot on the part of the assembly that is visible on the back you can observe if the magnetic assembly is rotating freely.
