      I get no reaction to M672 command.

      Power up 2 flashes.

      Probe input on SKRV1.4T (3 wires)

      M672 only works if there is also a command signal from the board to the Smart Effector, i.e. 4 wires.

        Fixed 4 wires
        M672 S131:131 works OK with 5 flashes. Boot up 2 flashes

        But if I try M672 S105:070:255 = nothing Invalid Z probe index

          That does not look like a valid command to me. See:

          To program the sensor, send command M672 S105:aaa:bbb replacing aaa by the desired sensitivity and bbb by 255 - aaa. The green LED will flash 4 times if the command is accepted. When you subsequently power up the effector, the green LED will flash three times instead of twice to indicate that a custom sensitivity is being used.
          

          So the 3rd value needs to be 255 minus the second value. In this case 255-70 = 185. What happens if you send: M672 S105:070:185?

              I get no where with this M672 sensitivity setting. Tried both P5 and P8 and up to 50:205 and I get sporadic jump overs.
              Can this be my step setting?

                Running G29 I get sporadic triggers with no Z moving, is there a way to adjust the sensitivity?
                Triggers at H height

                Is it triggering when the machine is idle, not moving?

                If so, does it make a difference whether the hot end fan and/or print cooling fan are running?

                  No fans active - no magnets on effector

                  G29 and tiggers on point where it should go down.

                  Tried now with higher µsteps
                  M92 X80.00 Y80.00 Z80.00 E80.00 ; set steps per mm
                  M350 X256 Y256 Z256 E16 I1 ; configure microstepping with interpolation

                  This gives much better result, but I think I need to adjust belts that sound to be cogging.

                    Still sporadic trigging, need some rest to clear my head.

                    I noticed following. when homed and issuing G29 I can observe several triggs with LED flickering.
                    This even with 55:200.

                    Also I can see push-down of bed position from 12 to 4 in outer positions.

                    Something is fishy for sure.

                      @tecno please answer the first question in my previous post. Also tell us what M558 command you are using.

                                @tecno OK; the Z-0.72 reminds me of the smart effector I got that was faulty...

                                The other one is incredibly sensitive, I initially set it at -0.1 but to get a correct first layer it seems better at Z0.0 !
                                That's with all default settings.

                                DC42 is the authority on that, though; I'm just another Duet user.

                                  Try reducing the probing Z acceleration, using M201.1 if you are running 3.4.0RC firmware, or M201 if not. High Z acceleration combined with a high mass hot end create the same strain in the effector at the start of the probing move as nozzle contact does.

                                      @tecno try even lower, e.g. 100.

                                      Also, if the green LED flashes at the end of the XY travel move rather than at the start of the probing move, increase the M558 R parameter.
