      I just had a look at your homing files from your first post. Are you still using those same files? They are set up to use a endstop switch, not the probe.

      Compare your files to this: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z_using_a_Z_probe

              In config.g you have M280 P3 S10 I1 ; Alarm Release and Push-Pin down
              But I don't think you want to deploy the pin at startup. I think S10 is just deploy, not alarm release. based on the Antclabs documentation: https://5020dafe-17d8-4c4c-bf3b-914a8fdd5140.filesusr.com/ugd/f5a1c8_d40d077cf5c24918bd25b6524f649f11.pdf

              Instead, try adding this to the end which will clear any error state and retract the pin. You can also add that to the start of the homez and homeall

              ; BLTOUCH PREP
              ;
              G4 S1 ; pause 1 second
              M280 P3 S160 I1 ; Alarm Release and Push-Pin UP just in case it's in alarm and deployed
              G4 S1 ; pause 1 second
              M402	; Retract probe just in case it's still down
              

              Your homeall will become this:

              ; homeall.g
              ; called to home all axes
              ;
              ; generated by RepRapFirmware Configuration Tool v2 on Mon May 13 2019 10:59:27 GMT+0100 (British Summer Time)
              G91                     ; relative positioning
              G1 Z5 F6000 S2          ; lift Z relative to current position
              G1 S1 X-290 Y-290 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
              G1 X5 Y5 F6000          ; go back a few mm
              G1 S1 X-290 Y-290 F360  ; move slowly to X and Y axis endstops once more (second pass)
              G90                     ; absolute positioning
              G1 X150 Y150 ; move probe to bed center. Change as needed.
              G30 ; use the probe
              G1 X0 Y0 ; return to home position
              

              And the same basically for homez, since you need to move X and Y to position the probe, you need X and Y homed first. So homez becomes redundant. Just use homeall. You can use homez for some other specific homing situation later if you wish.

                  Yes, except that you want the BLTouch prep stuff to happen FIRST before anything else to ensure the pin is up and any error cleared.

                      Can you also manually test the deploy and retract probe files by sending M401 and M402? They should deploy and retract the pin.

                      Post your deployprobe.g and retractprobe.g files if they don't work.

                            Which part is slow?

                            It looks like it worked?

                                If you send the command to do the self-test does it run continuously until you interrupt it? or does it still fail with a flashing error?

                                How bout this for homeall then. Change these lines to add a feed rate and the G30 will first do a fast probe and then slower ones.

                                G1 X150 Y150 F6000            ; move probe to bed center. Change as needed.
                                M558 F600 A1 		; Dive fast once 
                                G30			; probe Z
                                M558 F120 A10 		; Slow second dive with more accuracy
                                G30			; probe z again
                                G1 X0 Y0  F6000               ; return to home position

                                        @jobesynoob1234 said in bltouch v3.1 help😞:

                                        Looking at the BLTouch 3.1 manual it seems like self test is limited to 10 times now. So that's as expected.

                                          @Phaedrux well it worked faster probed center 3 times this time before going home πŸ˜ƒ so does this now mean i can sort my z offsets and G30 S1 should work πŸ€”
