      M42 P0 S1 G4 P500 M42 P0 S0

      Still continious, so question is if my M950 needs editing?

        @tecno what do you mean its still continuous?
        Are you using M42 in your config.g?

          No M42 in config.g

          M950 in config.g
          M5000.g in sys

          Console command M5000

          It triggers but does it coninously instead of one shot

            @tecno maybe 0.5s is too long, try reducing to P100
            Otherwise it sounds like you might need to add something to pull it back down to ground once released?

                Take away the 1K serial resistor on output?

                      What are the specs on the device you have connected to that output?

                      What does it expect to see in the way of signal voltage and duration?

                        The IO output goes go GND to trigger camera ( switch is NO and swithes to ground )

                                  Excellent.

                                  I did say:

                                  I would put a series resistor inline.
                                  Maybe 100 Ohms to 1,000 Ohms and try it.
                                  

                                  So I was already thinking 1,000 Ohms might be too large.

                                  I'm glad you stuck with the experiments and got it working!

                                    This inverts the signal and by that the level rises above the trigg point in the BT circuit, right?

                                      Experiments are always good as long one tries to follow good practis, in my case ask questions frequently.

                                      Thanks for guidance!

                                        Correct.

                                        Without that ! character the normal state of the output is low which is the state that triggers the camera. Adding that ! character makes the normal state of the output high.
