    I am trying to set up my card but i have no clue on how to wire in my bl touch. Also i have no clue how to set it up in the configurator. Do i need to setup "input Pin", "Modulation pin" and "PWM Control Channel (bl touch only)"?
    Also having issues figuring out how to setup 2 z motors using the config. I cannot assign a Endstop pin to E0 which is my 2nd z motor.
    When it comes to the fans do i need to connect the ground?
    I am adding my config if anyone wants to take a look.

    config.json

      https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+3+Mini+5++Guide+Part+1:+Wiring/87?lang=en

      Here's a wiring guide that includes a section on BLtouch.

      The config portion is coming soon, but here's the relevant portion of config for the BLTouch.

      M950 S0 C"io3.out" ; create servo pin 0 for BLTouch
      M558 P9 C"^io3.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

      You cannot setup dual z motors in the config tool, you mave to do it manually by editing the config,g and modifying the M584 command to map both drivers to your Z axis.

      https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping

      To add a second endstop for the zaxis you'll also have to modify the M574 command in config.g to include both endstop pins.

      There's an example here: https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors#Section_In_RepRapFirmware_Num_3

      I'm not sure I understand you fan question, but hopefully the wiring guide will clear up the fan wiring. But if it's a 2 wire fan you have + and - no ground.

          Sorry for the confusion. The io1 has been corrected to io3.

          It should be io3.in and io3.out

          In takes the trigger signal and out controls the servo pin.

            @Phaedrux Why cant i pick io3.in on drive z in config? i can only pick io1/io2 but i cant pick them for the bl touch.

                @Phaedrux nwm i figured it out. You set to sue bltouch further ahead in the config.

                    @Phaedrux i got everything wired up and the pin extend and retract but it does not light blue and it does not report a value. What could be wrong?

                      you will not see the bltouch value change, it triggers for a fraction of a second.

                      test it with g30 and triggering it by hand so you can power off if it does not stop.

                        @Veti i tried and the value on the webui will just show 0. I have tried while homing to and it will not report a value, so bed will continue even if the pin is triggered by me. Pretty sure it should light blue when active also.

                        I used these steps tio manually test also

                        "To test the setup with the nozzle maybe a 100mm up from the bed you can check if the trigger signal is reaching the Duet by attempting to extend the pin by using the following command:

                        M280 P0 S10

                        If all is well the web interface should report a value of ”0” or "N/A" in the Z probe column when the pin is extended. You can then lightly touch the extended probe pin to check that the value in the Z probe Column changes to “1000”

                        You can retract the pin again with

                        M280 P0 S90"

                          How exactly do you have it wired? And what does the M558 M950 commands look like in your config.g? Does it match what I showed above?

                          Are you wired to IO3 like this?

                            @Phaedrux it is just like in the picture, i made sure i have connection all the way to the probe using a multimeter so no broken wire.

                            i have not amde any changes to M950 or M558, It is just as the config did them.

                            M950 S0 C"io3.out"                                       ; create servo pin 0 for BLTouch

                              @Alucardi said in Duet 3 mini 5+ need help with wiring and config:

                              H350

                              Change that to H5. 350mm dive height is possibly problematic. But maybe not your problem here.

                              So just to recap. You're wired up to io_3 just like in the photo. Your config looks ok for io_3. And your deploy and retract macros look correct.

                              When you power on does the BLTouch do a self test?
                              Does sending M401 and M402 deploy and retract the pin?
                              Does sending G30 deploy the pin?
                              Does touching the pin after doing the G30 stop movement?

                                When you power on does the BLTouch do a self test? Yes
                                Does sending M401 and M402 deploy and retract the pin? Yes
                                Does sending G30 deploy the pin? Yes it deploys during homing.
                                Does touching the pin after doing the G30 stop movement? It reacts to me pushing it but wont stop bed going up.

                                  Then I suspect a bad connection on the white wire to io_3.in. That's the trigger signal wire. Retest continuity. Recrimp it. Make sure it's in the shell properly. Make sure it's on the right pin.

                                  As an additional check, please send M98 P"config.g" and report any errors. Also send M558 P9 and see if it reports back what you'd expect.

                                  Also post your homeall.g
