      I do not know what is going on here it was working then it wasnt working it still detracts and retracts when the board is powered on but I get this"

      Error: Probe already triggered at start of probing move ?????

      However when I run an M558 I get this:

      M558

        As a first step you can execute M98 P"config.g" from the DWC console and check for any errors reported.

          @pickett do you have deploy and retract files in your sys folder? Do M401 and M402 deploy and retract the probe?

            @fcwilt I have tried the M98 P"config.g" and it returns no errors, none reported it just replies with the same command all highlighted in green?

            @jay_s_uk No I tried this already and it doesnt seem to retract or deploy said Z Probe? Is it unusual that it says Output Pin Nil?

            as seen above:

            Z Probe 0: type 9, input pin io3.in, output pin nil<<<-----?????

                @pickett don't worry about the output pin. It doesn't use one. It uses a servo pin which is set through M950

                  @jay_s_uk and yes FTM yes there are two separate files one for deployprobe and the other for retractprobe.g

                      @pickett where are the deploy and retract files and what's in them?
                      And the ^ isn't needed on io3.in
                      Can you also post a photo of the wiring at the duet end?

                        @pickett try adding parameter R0.2 to your M558 command. This is to give the probe time to deploy before you read it. Also remove the ^ as @jay_s_uk suggests.

                          YOU KNOW WHAT FOR SOME ODD EFFIN REASON I HAD PLACED IT IN io4 I feel so freaking dumb wow guys I do apologize I sincerely thank you for your time and efforts in helping me getting this resolved. WHen I had referenced the pic from the tutorial I had been using I realized I simply plugged it all back in to io4 and not io3.in/out wow I feel so silly thanks guys ok that does it until next time............... Quick question if any of you can..... can I use a mechanical endstop as in an endstop that simply completes a circuit in a mechanical fashion and use that for an endstop? Isnt this what endstops technically do anyways is to complete a circuit for a brief moment to trigger the END in a STOP?

                          I have this lovely looking endstop that is brass internals inside of a clear acrylic case and it looks freaking awesome and was wondering if I could use that as endstops. It even has this nice satisfying click when it is depressed? Here is a pic:
