        @re_tour Yeah, take a break. Start again tomorrow 🙂

        It will work now as it is. Maybe not perfectly but good enough to print PLA and stuff.

        With PC, ABS and ASA it need to be pretty spot on but with PLA it should work fine.

        You should not print those others anyway with your PTFE lined hotend.

          @gixxerfast You're right, I'll leave it be for today. I can't thank you enough for all the help, I would be nowhere without your assistance.

                @gixxerfast Hey there! So today I've tried the mesh and it works! This is what I see after running it:

                So now all is left is to slice the things I want in Cura and upload the gcode which I get? 😁

                  So I started the print, and the filament started to go in the opposite direction. I haven't the slightest clue why.

                      Thank you so much. Do I have to reverse it every time I turn the printer on or was it just an initial setting mistake I didn't pay attention to? 😁

                        @re_tour No, just change it once in config.g and it wasn't a mistake. Really hard to know how the wires are supposed to be, just as long as the pairs are correct it's good. Many has to adjust that AFAIK.

                            @gixxerfast So I didn't input that change into the config.g yet, but wrote it into the console. Printed 2 things, the strange thing is that at the end of each print the mechanism pulls the filament all the way out. Why could that be?

                              @re_tour You must have something wonky in your slicer. Check if there some custom end print gcode in Cura (it was Cura you were using, right?)

                                  @gixxerfast This is the last few lines of the first gcode:

                                    @re_tour said in Ender 3 RRF v1.1 setting up BLtouch:

                                    G1 E-2 F2700 ;Retract a bit G1 E-2 Z0.2 F2400 ;Retract and raise Z

                                    I really don't have a clue. I'm just guessing but...

                                    Try to find where these are inserted

                                    And comment them out /remove them.

                                    See if it makes any difference.

                                      @gixxerfast You were right, G1 E-2 F2700 pulls the filament nearly all the way out. Thank you (once again) 😁

                                        @re_tour That's great!
                                        Happy printing!

                                        I think you might have to revisit the offset configuration. The mesh looked a bit shifted. But that's for another day

                                        and as long as it prints and you get the first layer right, it works 🙂
