Iwere wrong with the c parameter.
I should use the C4 and not the C5.
Now i'm getting this result:
M591 D0
Pulse-type filament monitor on endstop input 4, enabled, sensitivity 0.06mm/pulse, allowed movement 50% to 140%, check every 6.0mm, current position 0.0, measured sensitivity 0.057mm/pulse, measured minimum 95%, maximum 105% over 548.4mm
i'll make some test now that is working.
I'll keep you up-to-date
Thanks again David
