      How do you have the BLTouch installed? Can you post a photo?

      When mounted correctly the base of the probe body should be ~8mm above the nozzle tip, which will result in a trigger height of ~2mm.

          Hi good people. My firmware is allready updated and working fine. Some others things ill have to do in the Macros i have but it stays for later. Now, about my Bltouch i have the follow problem. Independently off the value i put in G31, after the probe is done, the nozzle allways stays at 0,40 mm from the bed!!! I´ll show here my config file, for you ti check if is there anything missplaced.

          Sorry, dont know how to use </>!

            this is wrong. you need to find the correct beta value.

            G31 P500 X-40 Y-10 Z0 ; set Z probe trigger value, offset and trigger height

            you have not put in your actual value. after changing this, you need to restart the duet.

              @Veti Hi, thank you for the reply.
              In the first point you mention, how do i determine the beta value?

              In the second point, yes, i know. I have allready stablish "z" with the value the DWC determinate after G30 S-. In fact, i´ve give it different vlues, seen the first time, it stys 0,40 above the bed. I tried to low the nozzle a litle, increasing the "Z" value, but it stays allways at 0,40... regardless the value i have on "Z"!

                  so modify the G31 in the config and test the homing.

                    @Veti i have done it several times...i´ve defined Z to 0.23, the first value obtained with G30 S-1. After restart the duet, and do homing, the zozzle stoped 0,40 mm above the bed, but the Z value on the DWC is 0,23mm!
                    After that, i encreased the Z value 10 by 10 to check if the nozzle wold get closer to the bed! But nothing, it stays at 0,40mm all the times.

                      the config you see, i have "Z" value at "0", because i put it to "0" before a leave my printer last night. I intent to restart the configuration today.

                                @Veti it was not workig correctly either with the old firmware. After update the firmware, i already tried with 1.60 and it stops at 0,40mm.... the question is: Dont matter the value i define in G31 "Z", the probe will allways stop at 0,40 mm plus 5mm(because G1 Z5 F100 ) above the bed. If i down the nozzle by 5mm, in the DWC will show the "Z" Value defined on G31, but when i go measure with the wedge feeler, it is 0,40mm above the bed. Allways!

                                  do you use , or . ?
                                  since you never posted the config with a value in it its hard to tell

                                      send the G31 command to verify that your offset is put in correctly

                                        When you click that button in the post creation window it adds a section between three dots above and below. Put your code in the middle where it says code_text.

                                        code_text
