      I have set up my duet wifi and duex5 and I think I have everything I need to get going however I cannot seem to get my duex5 to execute any commands.

      I sent M115 and received a confirmation that my duex5 was connected. Are there any steps I need to take to get the duex5 to start working properly? I cannot seem to even get the fans to respond...

      M115 output:

      here is my config file:

          @injoi9000 According to your config.g, the only thing I can see that you have connected to the Duex5 is a single fan (P3). Everything else is configured for the Duet board. I'm a bit concerned when you say that you can't get the fans (plural) to respond. The only command that would yield a response from the Duex5 would be M106 P3 Snnn. Have you tried this - i.e M106 P3 S255?

            Have you provided VIN power to your DueX? It will be recognised by the Duet with just the ribbon cable connected.

                @deckingman So last night I did try that and it didn't work however this morning I did that ....and now it works.

                @dc42 yes everything is connected and now with the fan working there is definitely power.

                I plugged in my fan to the P3 position and now I have a servo connected to the PWM_1 position. What do I need to do to initialize the servo in my config file?

                  I have added the following lines to my config file and connected my servo to PWM_1

                  ; Servos
                  M307 H2 A-1 C-1 D-1 ; disable the E2 heater for the servo
                  M307 H3 A-1 C-1 D-1 ; disable the E3 heater for the servo

                  when I type M280 P3 S0 into the Gcode console....nothing happens 😞

                    Okkk

                    So somehow along the way I burned out my servo and that was the problem all along. Now with the following changes to the config.g and command I can get it to work.

                    1. plug servo into PWM_1
                    2. place this into config.g "M307 H3 A-1 C-1 D-1 ; disable the heater 3/PWM_1 for the servo"
                    3. type the following into the gcode console "M280 P3 S90" where changing the "S90" parameter changes the angle of the servo

                    I think my biggest issue is I thought H2 mapped to P3....so theres that.

                    SO NOW

                    How do I control a brushless motor with my servo controller?

                      I've done a little reading about ESCs, and it appears that some of them at least need to be calibrated. For example, see the calibration section at https://dronesandrovs.wordpress.com/2012/11/24/how-to-control-a-brushless-motor-esc-with-arduino/.
