      @nuroo Congratulations on getting it to work as intended!

      Now I'm left alone again with my "frame errors"/"sensor has stopped working" problem.
      May try to send it back to Filastruder as I am out of ideas now 😞

        @nuroo said in 25.95mm/rev, min -33% max 162% over 9615.6mm:

        Well ok. I need to make an extension and try again. I wish this requirement was noted to customer on product page or wiki. I'll report back.

        I am glad you got it working and thanks for the feedback, i have updated the installation section of the documentation to note the requirement: https://duet3d.dozuki.com/Wiki/Duet3dFilamentMonitor_RotatingMagnetVersion#Section_Installation

        @themelle i think asking filastruder to swap it will be a good test to see if this is a board that passed testing but is marginal in your setup.

          @t3p3tony Thanks for your honest feedback.
          May I direct Filastruder support to your post confirming a warranty swap?

                Well I thought I was good to go with correct setup.
                2 small 1 hour long prints no false positives. 11hour print - false trigger to little movement, about 5 hours in. Had to disable sensor so I didn't have to sit there having to keep resuming print.

                  Are there any other troubleshooting measures I could try?

                    @nuroo I got my sensor swapped as it seemed to be faulty. Since then I have been getting much better values - but I am running 70-130% allowed movement to compensate for spike values.
                    Maybe you also should loosen the grip a little bit 🙂

                      @themelle good to hear they swapped yours out. Figured I'd give the sensor another look.

                      I love that you can gather data while not actually having the printer stop.
                      Im current running:
                      M591 D0 P3 C3 S0 R85:115 L25.12 E3.0 (which worked on shorter prints)

                      S0 - disable filament monitoring.

                      So with my current longer print I did:
                      M591 D0
                      Duet3D rotating magnet filament monitor v2 on input 3, disabled, sensitivity 25.12mm/rev, allow 85% to 115%, check every 3.0mm, current pos 210.9, measured sensitivity 24.33mm/rev, min 1% max 110% over 6134.2mm

                      The high side range seems ok. Max I got is 110% but room for error still with 115%.
                      That min 1% is strange?? It would have surely triggered a pause had filament monitoring been enabled. But I have moved the sensor location as suggested. It reminds me of the min -33% I got starting this thread.

                      How do I over margin min 1% or min -33% so that these results are within good range?
                      For min 1% do i enter 0%? ie (M591 D0 P3 C3 S1 R0:115)??
                      For min -33% do i enter -40%? (M591 D0 P3 C3 S1 R-40:115)??
                      Can your algorithm handle such low values?
                      Do these low values still point to an issue with my setup?

                        @nuroo Please look out for frame errors reported by M122.
                        They went away with my replaced monitor, and so did the ultra-low min-values it got before.
