@t3p3tony Ok, I made my own and it seems to work now Here are my current values:
Duet3D rotating magnet filament monitor v3 on pin io1.in, disabled, sensitivity 24.80mm/rev, allow 70% to 130%, check every 3.0mm, version 3, mag 132 agc 62, measured sensitivity 24.92mm/rev, min 94% max 107% over 832.1mm
I enlarged the filament hole a little bit and smoothed out some edges for it so it cant get caught on any sharp edges, feeds easy and seems to allow the filament to bend a little to contact the encoder teeth better. I will share the Fusion 360 file and STL if you guys want it.
