    Can't speak specifically to Cura, but this :

    G28 ; home all axes
    G1 Z5 F5000 ; lift Z by 5mm
    M565 Z-1.0 ; set the offset for auto-leveling mechanism
    G29 ; run auto-level


    Should help

    @mark tomlinson Seems to autolevel now, but it pulls the filament back out of the extruder like.. 10cm? wth?

    Sounds like you have a retraction in there somewhere...

    Well, nothing in that startup GCode does a retraction :)

    Each line is documented:

    G28 ; home all axes
    G1 Z5 F5000 ; lift Z by 5mm
    M565 Z-1.0 ; set the offset for auto-leveling mechanism
    G29 ; run auto-level

    If anything you could remove the second line, but none of them cause a retraction

    Comment them out one my one (put a semicolon ; at the start of each line) and see which is causing the retraction

    I reset my machines settings before I changed the gcode.. so maybe its from that.. but do you know what would make it do that? Like the gear moves so fast I cant see it.

    That sort of action has to come from the slicer. So something must be sending a retraction command...
    Something is issuing a GCode to do a retraction:

    G92 E0 ; set extruder value back to 0
    G1 E-15 F300 ;retract 15mm filament speed 300

    The second line there is a retraction (the first one resets the extruder virtual position) but something must be issuing a:

    G1 E-xxxxx

    To get the retraction to happen

    I'm confused.. this is the start of the gcode:

    ;FLAVOR:RepRap
    ;TIME:90846
    ;Filament used: 54.1589m
    ;Layer height: 0.1
    ;Generated with Cura_SteamEngine 2.5.0
    M190 S60
    M104 S205
    M109 S205
    G28 ; home all axes
    G1 Z5 F5000 ; lift Z by 5mm
    M565 Z-1.0 ; set the offset for auto-leveling mechanism
    G29 ; run auto-level
    ;LAYER_COUNT:548
    ;LAYER:-9
    M107
    G0 F1800 X56.376 Y52.08 Z0.3
    G1 F900 X56.637 Y51.818 E0.04613



    Thanks for your help by the way
