      I've been trying to solve this by searching on the forum but I can not find any answers.
      Before I had a Duet Wifi + a duex2 board, now I upgraded to a Duex5 board and suddeny the BLTouch does not work.

      It's connected in the exact same place as it was on the Duex2 board, is there anything I need to change in the config when using a duex5 instead of a duex2?

        Where is it physically connected? Photo?
        Test the continuity of the wire?
        Post your config.g and the results of M122 and M98 P"config.g"

          @Phaedrux Hi!

          It's connected in the PWM_1 on the Duex 5 + the "Ground" and "Z_PROBE IN" on the Duet Wifi.

          I got this in my config.g:

          ; General preferences

          And I got this in deployprobe.g

          M280 P3 S10
          

          And I got this in retractprobe.g

          M280 P3 S90
          

          With the duex2 board it worked, now the BLTourch lights up all the time but does not work.

                I had a fualt on my which would not finish self test after rebuilding my hotend mount which I solved by adjusting the grub screw slighty. Worked ever since .

                  The strange thing is that the red LED lights up all the time, and none of the self test/other commands work. Only thing I did was change from Duex2 to a Duex5.

                    my bl touch v3.1 was staying red on startup when it could not complete its self test. I thought it was the wiring after moving it upto the printer and extending the cables but they tested ok and after reading someone elses post they mentioned the grub screw which I had not touched. So I gave it a little adjustment turned the printer back on and it completed it self test straight away as normal. Give it a go it might work.

                      @Javajoeuk Ok! I will test that!
                      You mean the little screw on the top of the BLTouch right?

                          Any other idea? 😃

                                can you try a different pwm port?

                                      Try disabling heater 7 and use PWM5 on the DueX, that's a common combination.

                                          Do I need to change anything more then this: M307 H7 A-1 C-1 D-1 ?
                                          And remove the M307 from config-override.g

                                            You'll also have to update your deploy and retract macros to reference the new pin number as well.
