      still confused why the bltouch is not performing the self test at start up. other than that it appears to be operating correctly

        I say mine, maybe it has been tried but you never know.
        If with the machine off you pull out the pin and then turn it on, does the Bltouch work? Yes?
        If yes, make the extension wiring new from scratch ... I change wires I used the Cat5 ones for network cables and above all crimp the terminals well (and with the pliers).

          The BLTouch works, just does not perform the default self test when it printer is turned on

            Do you have the alarm release at the start of config.g?

              @Phaedrux I've got it right under general preferences

              When I power it up the BLTouch will blink its read, but running Alarm Release and Push Pin Up (M280 P7 S160 I1) results in no change.

              Only running Alarm Release & Touch SW Mode (M280 P7 S60 I1) stops the blinking, but then I have to run Push Pin Up (M280 P7 S90) so that it works correctly after.

                Maybe move alarm release to the end of config. G to give it time to finish the self test.

                    Well new problems creeping up. Pin will not retract at start of print but print starts regardless.

                    I'm going to try a fresh install of firmware and start that from scratch to ensure updating did not cause any issues. What is the best method for this?

                      @jaurand Upload the firmware on the system tab of DWC and it should update automatically.

                        @Phaedrux that is how i've been updating firmware before. My thought is something did not stick right causing my issues. Hence why delete it all and start from a fresh build is my thought

                          Can you post your config.g, homeall.g, and your deployprobe.g and retractprobe.g files from the /sys folder?

                              M558 P9 X0 Y0 Z1 H5 F100 T2000

                              Remove the X0 Y0 Z1 from this command. Those parameters are no longer used.

                              G31 X0 Y0 Z3.467 P25

                              You're missing the X and Y offset between the nozzle and the BLTouch.

                              Neither of those should be show stoppers however.

                              All I can suggest at this point if you're 100% confident that your wiring is good, is to try switching to heater pin 3 of the expansion header instead of using heater pin 7.

                              You'll need to change the heater unbinding to reflect H3 instead of H7

                              M307 H7 A-1 C-1 D-1 ; Disable the 7th Heater to free up PWM channel 5

                              And check config-override.g to remove any entry for H3.

                              As well as change the servo commands to target P3 instead of P7.

                                When I switched to H3 I get no response

                                    M501 ; Load saved parameters from non-volatile memory

                                    I assumed you had a config-override.g since you have an M501 in your config.g to load it. It's fine if you don't have it thought. It just means you haven't used M500 to save any PID tuning values.

                                      @Phaedrux ah yes since I typed my values directly in.

                                      So since H3 doesn't work is that a bigger problem?

                                        I'm still inclined to think it's a wiring issue.

                                        Can you make up a brand new very short wiring harness to test with?

                                          @jaurand said in BLTouch V3.0 Reassemble:

                                          I have had many instances lately of the push pin breaking off many times as well as unresponsiveness from the BLTouch itself.

                                          It could also be a bad probe. Perhaps time to get another to try?

                                            @Phaedrux well I do have three BLTouch, two V3 and one version 2. I'll try some wiring and see what I get.
