      Hello,

      I have issues with my filament sensors since the firmeware versions 3.3beta1
      The sensors are connected to expansion boards, together with the extruder motors.
      This setup did work on the firmeware 3.2, but since 3.3beta1 the input pins wont give back any signal (the filament sensor readout with M122 always says filament present). I have tried pluging a sensor and motor to the mainboard, which works fine. Other inputs like endstops in the expansions work fine.
      (all boards are 3.3beta3)

      Is this an known issue and will be fixed later on?

      greetings Valentin

        Can you provide your config.g and the results of M122 and M122 B1?

          It looks like the individual board麓s get it right. The sensor on 2.io2 should return no filament, the other three are loaded.

            I did another test just now, and they worked. I have no Idea why, but the M122 is still saying no filament on all 4 extruders.

              Can you update to RC1 and see if it's the same? Maybe a display bug in M122 output.

                  @vali3d do M591 D0, M591 D1, M591 D2 and M591 D3 return the correct status?

                  What type of filament sensors are they? Please show us the M591 lines in config.g that you use to configure them.

                    config (2).g

                    M591 D0 P1 C"1.io2.in" S1
                    M591 D1 P1 C"2.io1.in" S1
                    M591 D2 P1 C"2.io2.in" S1
                    M591 D3 P1 C"2.io3.in" S1

                    The sensors are simple switches (high signal when filament present).
                    Like I wirten, in the M122 B1/B2 the readout is correct.

                    Driver 0: ok
                    Driver 1: no filament
                    Driver 2: ok

                    Driver 2: ok

                    5.5.2021, 09:01:04 M591 D3
                    Simple filament sensor on pin 2.io3.in, enabled, output low when no filament, filament present: yes

                    Simple filament sensor on pin 2.io2.in, enabled, output low when no filament, filament present: no

                      @vali3d thanks, so it's just the M122 main board filament monitor summary that is wrong. I'll log this as a known issue for fixing in a future release.

                        at my first try, the sensors didn麓t work(3.3beta1/3). One day later, without any changes they did work(3.3beta3and 3.3RC1). Since then they do work and only the M122 readout is wrong(3.3RC1).
