      Thanks but Flow is tuned right but it won’t work this this beta release. Flashing to previous build or Klipper and the problem is gone.

        @dc42 Is there a scanning z probe that you have tried or could recommend?

          @lparnell34 I am looking at two scanning Z probe solutions. One is a version of our IR sensor, with modified firmware to produce an output related to the height of the sensor above the bed plate. This may work if we can find a suitable consistent surface to use with the sensor. Some of the modern flex plates may be suitable. The second is a small inductive sensor add-on to our tool board.

            This sounds very good in my ears as I can not get Smart Effector to work properly.
            Been planing to do this on my Big Delta.

              Which version Smart Effector do you have, and what is the problem you are having?

                It is 3.0
                Not same sensitivity on print area that is approx 450mm in diameter = No reliable mesh.

                Also I suspect the mounting of the extruder /adapter may cause issues as well.

                  @tecno if the extruder is clamped tightly to the effector, that may affect the sensitivity. Can you try adding 3 nylon washers between the printed part and the effector, and 3 nylon washers under the nuts or screw heads on the underside too?

                    I will try that.

                    Question: best way how to connect this inductive sensor to Effector or directly to Mini5+?

                    This if I can not get Effctor sensityvity to act as it should.

                      i remember when i designed the mount for lgx lite for my smart effector the first 3 iterrations of the mount was just like that and never had a good probe because the mount interfere with the strain gauge of the effector...and then i decided to raise it a bit and that sorted out...this is how it looks righ now photo_2023-05-05_17-30-39.jpg

                      i added some spacers to the mount to raise it from the smart effector then i integrate them on the final deignphoto_2023-05-05_17-34-58.jpg

                        @tecno my first advice is: always choose a NPN sensor, not a PNP sensor.

                        You can connect a PNP sensor to either the Duet or the tool board using two resistors. See the wiki page on connecting a Z probe.

                          In 2-wire mode NPN or PNP for this sensor

                            @tecno you would need to use a pullup resistor between the output and voltage source of 10V or more to use it in NPN mode. The resistor would have to be chosen so that the 0.9mA leakage didn't trigger the Duet, but when triggered the load was at least 4mA. For example, a 3K or lower resistor to +12V, or a 6K or lower resistor to +24V. If you go this route, do the sums to ensure that the resistor can dissipate the required power. There will almost certainly be a voltage drop when triggered, and this may be too much for the Duet to recognise it as triggered.

                              In 3 wire mode yes

                              But how about 2-wire mode?

                                @tecno as I indicated in my previous response, to use 2-wire mode you would need to add a pullup resistor to +10V or greater to meet the minimum voltage and current requirements, and even then it might not work because the voltage drop when triggered in 2-wire mode has not been specified.
