      Have you verified that the trace has been cut to enable 3.3v logic?

        I really understand nothing.

        Yes I think it's good to cut
        I have 2 bltouch, and it does not behave in the same way! see video

        The, I despair, can I back down version (2.01 to 1.20) easily? That way I can apply the tutorial and especially print ...
        There is the option to change sensors but the IR does not seem to me well suited with a glass plate. I often use geckotek ...

        It remains the options I send videos (I am bad in English and google not always very good for the technique) and I await your analysis. I thank you for that again.

          The tutorial should apply the same regardless of firmware version. But if you absolutely want to downgrade it should be as easy as uploading the older firmware. You may also need to upload the older wifi server and DWC files as well. But ideally I think you should try to get it working with 2.01 due to the other bug fixes and enhancements.

          I would suggest going over the wiring very carefully and checking for any loose crimps or broken wires. Check for continuity with a multimeter. Double check you are using the right pins. Recut the trace.

            Hello,

            You were right one of the bltouch had bad contact. I solved this problem.
            But DC42's advice to remove M98 (deployprobe.g and retractprobe.g) does not solve the problem.
            I always have the Bltouch that starts the probing and after some probing (it's random, never the same point), it blinks.

              Check the Z probe reading in the web interface when the BLTouch is deployed but the pin has not been pushed up. It should be zero. If it is about 1000, then either you have not selected the correct mode in M558 (it should be P9, and you should not have the I1 parameter), or there is a bad connection between the Duet and the white wire of the BLTouch.

                Everything works perfect for bltouch with up, down, reset and self test macros.
                But as soon as I go on an autocalibration the bltouch flashes on randomly on the 1st probing.

                Do not do M561 and or G32 S2 for "reset" what is already register?

                What information can I give you to simplify your expertise?

                  Does that mean that you get the correct Z probe reading, or haven't you checked it?

                    Sorry, I'm French and I do not understand what you mean.

                    It has been several times that I turn on my printer and that communication is impossible. the wifi light is lit. It is very hot in France (31 in my garage) but I have the original Tevo fan that works.

                    I do not understand why the bltouch works perfectly by sending the up, down, reset and selftest commands individually but when I run the auto calibration, the bltouch does some probing and can not finish the autocalibration.

                    I do not know what to do and I just have to hope that you will find what I did wrong or forgot to do.

                        Ok I understand what you mean now but google must translate poorly what I tell you.

                        When there is no i1 in deployprobe.g and retractprobe.g to do auto-calibration or macros, the bltouch commands do not work.

                        I checked all my connector and crimp (welded) to the multimeter, no problem.

                        After some probing, the bltouch goes up and down which makes it blink.

                          From your videos it looks like the probe pin is sticking. Earlier you said you had tried to repair it by taking the pin out?

                          Try this, put the probe into self test where it deploys and retracts the pin repeatedly and leave it running for a long while. The probe should continue indefinitely. If it gets stuck and goes into error that means that the pin is likely getting stuck. If this is the case you may need to replace the probe. The newer versions of the BLTouch are quite improved over the older style. The pins are now plastic for instance. Given the cost it may be worth just replacing it.

                            You still haven't answered my original question: is the Z probe reading shown by DWC zero (or close to zero) when the probe is not triggered?

                              I launched the selt-test at 22:44 and at 22:57 it was still running. So it works well in the void.

                              Yes I think I have this option to buy a newer, newer bltouch that will be the least expensive. But there is also buy the complete delta kit Duet3D Smart Effector. this will allow me to be more precise from what it says on any bed surface.

                                what is DWC?

                                Z-probe remains always displayed at 0 pin down, pin up and selt-test.

                                  I just launched the auto calib, it was 2 probes and the sensor has increased to 1000.

                                    it's still weird to have a 2 bltouch that does not work? it is not a problem of speed of retraction of the bltouch and or the speed of mounting of the head too slow?

                                    in a first time this model will go?

                                      I exceeded my support credit or tried to understand what I'm doing wrong? I'm still at the same point, impossible to print. I have an old-fashioned configuration solution without bltouch?

                                      Thanks you

                                        What is the correct version of the web server? Why I have 1.21 RC4 after the update?

                                        Thank you

                                          @rafb do you have the deployprobe.g and retractprobe.g files in the same file location as the config file?
