      I was in doubt of creating a new post or not so I im doing it wrong, please forgive me.

      Im using a pulse encoder
      I have connect it, it is working, and after an extrusion I get:

      M591 D0
      Pulse-type filament monitor on pin io2.in, enabled, sensitivity 0.370mm/pulse, allowed movement 10% to 200%, check every 3.0mm, measured sensitivity 0.372mm/pulse, measured minimum 20%, maximum 137% over 398.9mm

      0.37mm was a calcylated number, the measured number was 0.372 so calculations are pretty much the same. Nevertheless the firmware says the measured error was on the range of 20% min and 137% max.

      is this ok? what is exactly the meaning of those numbers because if the theoretical number almos matches the real measured sensitivity (error seems to be onlt 2 thounsends of mm) the reported error doesnt make sense to me

      Any clarification will be apreciated, thanks in advance

      It is a duet3, on SBC mode, firmware 3.4.6
