      @billsrf said in Z-probe triggers way above table during HOME ALL:

      @dc42 yes it flashes just like it is at the bed

      Can you confirm that it flashes just once? Not 2 or 4 times, like it does when it initialises?

        it is roughly 50mm above the bed, it flashed 1 time just like normal then moves up 5mm. 0_1555960761051_Z probe.JPG

          This looks a little off from your config.g.

          Is the probe really X570 and Y570 away from your nozzle?

          You also haven't calibrated the Z trigger height.

            after home.all, I can push HOME.Z and it moves to the bed and sets the correct nozzle height

              @phaedrux i have the offset Z trigger height set to zero for testing. What should the X-Y settings be for the G31? isnt it center of my build plate?

                @billsrf The X and Y values for G31 should be the distance of the probe from the nozzle. Just as the Z value is the distance from the probe to the nozzle tip in Z.

                If the probe is to the left, the value will be -x.
                If the probe is to the right, the value will be +x.
                If the probe is to the front, the value will be -y.
                If the probe is to the back, the value will be +y.

                  my BED.G looks like it is missing a lot of information now for some reason. 0_1555961191732_bed.g

                    It looks like your bed.g is currently setup to just do a mesh grid compensation run.

                      @phaedrux ok, i will measure the offset and change that in the G31 in config.g

                        If I am not using a bed compensation. Why would that be making my trigger so high off my build surface? It moves down about 20 mm then triggers during home.all. But, if i do a home.z afterwards it moves to the correct trigger height and it is ready to go

                            yes 9 times. I will change the offsets and then go through the probe set up again

                              @dc42 went through the same set up process as described in test and calibrate Z probe, same results as before, it moves down 10 mm then triggers then stops. I did nottice, as it is moving towards the X-Y home position, the IR sensor flashes 3 times like it is just initialized. Never done that before either.

                                    Is the sensor on the IR probe dirty or damaged at all?

                                      @phaedrux No, i have even swapped it out with a new probe and it does the same thing!! I am baffled!!! to say the least. As you can see it won't run a G29 anymore either

                                        @phaedrux I have another Duet3d wifi board, I am going to swap it out in the morning and reload my firmware and see if that does it
