        Error: Z probe already triggered at start of probing move.

        Also, the machine continuously crashes to X axis endstop for 1 sec.....

            No. Only if I hit the G30 S-1 or the Bed Mesh compensation

              Did you move the print head to bed center with the nozzle just touching the bed before doing G30 S-1?

                  So it goes from bed center to crash into the x endstop?

                          You don't have the i1 parameter in the M558 command, If the sensor is a naked piezo cylinder (which is what it looks like), you must use i1 in that command as I said in my previous email, otherwise you will get the "already triggered" error.

                            @Phaedrux Thank you for taking the time and helping me out.
                            The truth is, there is so much time lost and solution is not found.

                            If we accept the fact, that Duet is not compatible with this sensor, what are the other options available???
                            All I have is a BLclone and mechanical endstop. Bear in mind, I am seeking the easiest solution available, as I just learned G code, previous motherboard was plugNplay

                              @dc42 Just added I1 and the nozzle crashed to bed on mesh compensation.
                              However, it did home correctly.

                                @dc42 While crashing onto the bed, I got this error

                                  Like I said before, test with the polarity reversed. Also test at different Z probing speeds (F parameter in the M558 command). See https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe for how to test it.

                                  However, a naked piezo cylinder is a very primitive type of Z probe, and reliably operation may be hard to achieve. You might possibly find that P1 in the M558 command along with i0 works better than P8 (again, try both polarities).

                                    Might want to trigger it by hand while testing rather than wait for it to contact the bed just in case. That way you can kill power if it doesn't trigger as expected.

                                      @dc42 Okay, I tried P1 mode while erasing I1 , I didn't get a single error.

                                      However, it crashes onto X endstop for 1sec continuously

                                            The X (not Z) endstop? That's a different problem.
