      Hi veti,
      I dont realy know how many mm does it retracts. This is the default settings on CURA.
      Do you think i should remove the line "G1 X5 Y5 F3000 ;Wipe out"?

      About the retraction, what i wold like, is for the printer retracts about 50mm, so the filament doesnt cook in the hotend wile its cooling.

        i dont know your printer. does it wipe the filament with a brush or something at x5 y5?

        About the retraction, what i wold like, is for the printer retracts about 50mm, so the filament doesnt cook in the hotend wile its cooling.

        so just increase the retraction amount in the end script from 2mm to 50mm

          Probably it is not wiping out.... it just stays on top of my print distroying it! Dont know what to do about it!
          About the retracction, ok, i will put 50mm instead of 2, but the issue is that in the end, it retracts all the way

            so define the coordinates in x and y where you want the printhead to move and put it in the end code.

                In Cura find the setting for relative extrusion. Usually if the end of print retraction is removing all of the filament it's because it's set to absolute extrusion mode and is trying to move the extruder position back to what it was at the very start of the print.

                Alternatively, just add an M83 right before your retraction commands in the end gcode to switch it to relative extruder moves for just that part.

                          Its the only place i find absolute mode for the extruder at the G-code!

                            I suspect that if you look at a sliced gcode from cura you'd find an M82 at the beginning as well.

                            You can remove that M82 from the end gcode.

                            In Cura the setting for relative extrusion is in the Special moves area. Maybe hidden by default.

                              Yes, i read about that in this forum but i couldnt find that kind of hidden code. I used the m83 and it worked fine. Tks a lot Phaedrux
