      Looking for some clarification on how to setup 5v logic as per the Bltouch V3 manual or if it is needed.

      I have wired my BLTouch exactly as in the following link

      https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/

      If I need the 5V setup using heater 7 pin, how do I implement this in the config file? Is it simply M280 Px S140? Where Px would be what then?

        You shouldn't need to do anything at all to get the V3 working. Just connect it and configure it.

          Hi,

          I have a Duet2 WiFi/Duex5 setup and I use the PWM5 connector for my BLTouch v3.0.

          I don't configure my Z-probe in config.g but in a separate file configprobe.g.

          M307 H7 A-1 C-1 D-1 ; enable use the PWM5 connector for the BLTouch
          M558 P9 H5 F300 T6000 A5 S0.01 R0.2 ; probe setup step 1
          G31 X-44 Y0 Z1.450 P25 ; probe setup step 2
          M280 P7 S160 ; clear BLTouch alarm (if any)

          Using a separate file allows me to quickly test changes in probe configuration without rebooting AND allows me to call the configprobe.g from multiple places.

          I used the BLTouch as it came out of the package.

            I had version 2 before working then the pin broke so I primed a new one.

            I thought it would just be plug and play, but i read this post and was unsure

              Yeah it's a little confusing, but most of the issues surrounding the V3 were with Marlin. No changes or special actions were required with RRF and Duet hardware.

              No more resistors, or traces to cut, or anything like that.

                  @fcwilt do you have to step config.g to look for configprobe.g?

                    Sorry but I don't understand the question.

                    I have a reference to configprobe.g where it is needed, such as when homing the Z axis, but no reference appears in config.g as it is not needed.

                      @fcwilt Sorry I fat fingered. What goes in the config.g so that configprobe.g works? I assume I cannot just make a configprobe.g with all the probe values and have config.g with no probe info

                        @jaurand you can actually. Config.g doesn't need anything for the probe, so long as configprobe.g has all the needed commands and it gets called before the probe is activated for probing.

                        The only thing special about config.g is that it called called at startup. It's a macro like any other. Just a list of commands.

                            please open your own thread. otherwise it becomes confusing.
                            your problem is most likely with wrong or faulty wiring.
