what am I missing?

@j3dk See https://duet3d.dozuki.com/Wiki/Duet3dFilamentMonitor_RotatingMagnetVersion#Section_Duet_Num_3 for connecting.

M591 P3 C"e0_stop" S1 ; filament monitor connected to E0_stop

Change C"e0_stop" (which is Duet 2 pin name) to C"io[x].in" where [x] is the IO connector you have connected the sensor to.

@droftarts Hi there thank you for the advise. now I have figured it out putting this line in my config.g it works
M591 D0.3 P3 C"^io5.in" S1 ; filament monitor connected to E0_stop

@j3dk said in how to configure magnetic filament sensor on duet 3 mini 5+:

C"^io5.in"

You shouldn't need the ^ character in the pin name, it enables the pullup resistor.
