      M558 and M950
      hotend goes to middle of the bed and deploys probe then probe swiches off I think

        @Elvis0z you should check G31 Z value also, please see my last post above.

        In homeall I would move the hotend to the middle of the bed before probing Z, instead G1 X15 Y15 F6000 I would call
        G1 X100 Y100 F6000
        to be sure you don't probe outside of the bed one day and not triggering (when bed or endstop moved a bit eg).

          This was the last error

            @Elvis0z was your bltouch over the bed and was it deployed?

                  @Elvis0z did it have a bit of distance to the bed? There are some documentation to the installation. The Z height in reference to the nozzle is important.
                  The image right lower on page 1 in the https://locxess.de/3d/BLTouch_Anleitung_englisch.pdf
                  document, the 8mm.

                    Yep it probes way above the bed.

                          @Elvis0z to be sure: your BLtouch is right and behind the nozzle?

                              @Elvis0z are you sure G31 Z is 0? This would mean the BLtouch triggers when the nozzle touches the bed.
                              Please recheck steps 5-7 in https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Calibrate_the_Z_probe_trigger_height . You could trial and error some values for Z also... (Z positive) - I would do that 😉

                              I don't see other problems, I would only remove the + signs from
                              G31 P25 X+41 Y+10 Z0.0
                              they will probably be interpreted correctly, but I didn't see + signs in the examples, so to be sure, I would remove them.

                                As it won't home z
                                Should I just manually move the hotend to the bed

                                  @Elvis0z you can of course move Z carefully down with the small G1 Z movements (+Z0.1 etc) until you have the famous one-sheet-paper-distance, then say G92 Z0 to set 0 position. But this is no general solution. There must be a reason why it is not working as expected.
                                  Maybe someone other has an idea what's wrong.

                                          Hey guys need help to set this up its a v1.0 bltouch.

                                          Is this a version with the trace to cut or does it come with the resistor? It's been a long time since I've seen anyone with a V1, so I'm wondering if it matters in this case. If it's a new Duet 1.04 it can't be hurt by 5v, but perhaps there is something in the BLtouch that will not trigger. If removing the ^ and checking your white wire is fruitless, maybe look into the trace/resistor
