      hi,
      I try to home with max acceleration at 500 and it work, but after I change to 800 and now it pass in front of the sensor (induction sensor) but it doesn't detect it.
      But this depend of the feed rate:
      F360 it fail but F400 and higher it work.

      M574
      Endstop configuration:
      X: high end switch connected to pin 40.io1.in, min interval 30ms
      Y: none
      Z: none
      

      It is maybe the min interval how is to high ?

        I have the same problem when I try to home all axis.. But now whatever the speed, it is always the second pass how fail (the axis continue moving even if the shitch is activated)

            @dc42 hi, I found what cause the error, I think it is a software bug.

            For exemple:
            this work:

            G1 H1 X1005 F3200
            

            but this fail:

            G1 H1 X1005 F360
            

            And to correct it :

            G1 H1 X100 F360
            

            It is when the travel at low speed it's long that the end stop it's not detected (the machine didn't stop when it is activated).

            I make some tests:

            work:
            G1 H1 Y700 F360
            
            fail:
            G1 H1 Y800 F360
            

            When the speed increase the distance can be higher before it fail:

            work:
            G1 H1 Y800 F500
            fail:
            G1 H1 Y900 F500

              are you running firmware version 3.2 and have you updated the firmware on the toolboards as well?

                See this list of limitations and check if any apply to you

                https://duet3d.dozuki.com/Wiki/Duet_3_firmware_configuration_limitations

                specifically

                Endstop switches and Z probes connected to the main board cannot control motors on an expansion board. This is planned to be fixed in release 3.4.

                    I use 3 expansion board 1XD for the 3 endstops (one on each).
                    For the firmware I use RC1 because I don't find an other version for the 1XD.
                    And here is my config file:

                      @dc42, those are the corrected versions:
                      for all axis:

                      ; homeall.g
                      ; called to home all axes
                      ;
                      ; generated by RepRapFirmware Configuration Tool v3.1.9 on Wed Dec 02 2020 13:29:43 GMT+0100 (heure normale d’Europe centrale)
                      G91                     ; relative positioning
                      M98 P"homez.g"
                      G1 H1 X1005 Y1005 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
                      G1 H2 X-15 Y-15 F6000     ; go back a few mm
                      G1 H1 X20 Y20 F360  ; move slowly to X and Y axis endstops once more (second pass)
                      G90                     ; absolute positioning
                      G92 Z800                  ; set Z position to axis max (you may want to adjust this)
                      
                      ; Uncomment the following lines to lift Z after probing
                      ;G91                    ; relative positioning
                      ;G1 Z5 F100             ; lift Z relative to current position

                      for the X axis (Y and Z are the same):

                      ; homex.g
                      ; called to home the X axis
                      G91               ; relative positioning
                      G1 H1 X1005 F3200 ; move quickly to X axis endstop and stop there (first pass)
                      G1 H2 X-15 F6000   ; go back a few mm
                      G1 H1 X20 F360  ; move slowly to X axis endstop once more (second pass)
                      G90               ; absolute positioning

                        @Phaedrux I didn't find this web page before.

                        This one maybe appliy,

                        Stalls of expansion board motors are not yet reported and cannot be used for homing

                        but with this limitation:

                        Endstop switches and Z probes connected to the main board cannot control motors on an expansion board. This is planned to be fixed in release 3.4.

                        If I understood correctly, the expansion 1XD is made to connect motor but we cannot connect an endstop switch to them and we can connect the endstop switch to the main board when the motor is on the expansion board. So we just cannot use the expansion 1XD for motors ?

                          You can connect endstop switches to 1XD boards.
