That solved it...much better results now....94% to 103%. AGC is now 96.
Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 26.92mm/rev, allow 1% to 200%, check every 3.0mm, version 3, mag 132 agc 96, measured sensitivity 25.21mm/rev, min 94% max 103% over 1721.6mm
Ack...I screwed up the command that I posted above. I just sent a new command down and it correctly updated the range to 30% to 200%.

Triangle sensor ordered thanks!
I ended up sending
M591 D0 P3 C"io2.in" L24.93 R30:200 S1 A0
However, I'm still periodically getting too little movement errors. Looks like I'm dipping down below 30%. In the below instance, I caught the system dipping down to 48%.

My whole objective with the filament monitor is to just detect the end of the spool, so that the system can pause, I can load up more filament, and keep on going.
But it has too many false positives to be useful.

Just sent M591 D0 L30:200
Just got back...so that didn't update it

Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 30.00mm/rev, allow 60% to 160%, check printing moves every 3.0mm, version 3, mag 132 agc 87, measured sensitivity 24.93mm/rev, min 97% max 103% over 2113.6mm
I'm on layer 249 of a 900 layer print. The print ran for hours, but got a too little movement error overnight and then that error has been increasing throughout the day. I just hit unpause each time to get the print going again.
I had not used my 3D printer in a long time prior to a test print just before this larger print. I upgraded the firmware (Duet 3 mini 5) to 3.4.6 and I turned the filament sensor back on using the following command. I did not have issues with the test print and therefore thought that I was good to go with larger print.

When I run M591 D0 in the console right now, I get:
Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check printing moves every 3.0mm, version 3, mag 131 agc 87, measured sensitivity 24.93mm/rev, min 97% max 103% over 534.4mm
Can I send another M591 D0 P3 C"io2.in" S2 L20:200 command through the console to update the filament monitor setting while the print is running? Or is that going to derail things?
Thanks for your help!
I had a successful 13 hour print yesterday. I kicked off a new 9 hour print and the printer kept pausing due to "too little movement on extruder".
This seems to be in line with alankilian's comment above that he had to disable his because he couldn't stop false positives.
Note that there was a pause generated by the filament sensor just before the 6:31AM M591 D0 call.
Any suggestions on how to correct this?
I'd like the magnetic filament sensor to just say...I've stopped rotating completely...must be out of filament so put the system into pause.
Is the sensor not taking into account retraction and rewards movement of the filament?
Ugghh. Yesterday I did two five hour prints with no problem.
This morning, I kicked off a 13 hour print and I just found it 12 hours later where it had printed the first layer and then paused the print for "too little movement on the extruder".
M591 D0 output is as follows
Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 25.74mm/rev, allow 70% to 130%, check every 3.0mm, version 3, mag 132 agc 91, measured sensitivity 26.25mm/rev, min 45% max 106% over 244.6mm
I just opened up the allowable range to 20% to 150% to try to give it a wider tolerance.

After thinking about this more, I think I need to initially set the low and high limit very wide. Then get the measured sensitivity over a print, set the sensitivity to that value and then update the limits to say 50% and 150%.
I just implemented the rotating magnetic filament sensor. My print keeps pausing with a message that "too little movement" was detected on the sensor.
Any thoughts on this?
Here is output from M591 D0.
