@snimax said in Magnetic Filament Monitor skips values:

@christophe There is a bugfix in the 3.4 release candidate that fixes possible race conditions and that short extruder moves are sometimes missed by filament sensors. If possible you could try it out and see if it solves your problems 🙂

@Snimax With the new firmware Duet 3 Mini 5+ 3.4.0rc1 (2022-02-09) it lasted a lot longer (about 150m of filament) but then the min went down to 9%, and again shortly after that with a second test.

The polling is every 500ms, so the logs seems to be right. But it changes from 2991 to 3006. Which is a difference of 15mm instead of the defined 5mm
