    i am slicing using CURA 2.5 the generic version that comes with the C2.

    recently when I send a file to print sliced via CURA either through the program or saved and sent via Octoprint my x offset is off. It prints just above the print bed on one side.

    however if I reprint old files I have saved from years ago they print great without issue.

    thoughts on where I should go?

    Well, the slicer would be my guess (since older, sliced files print fine).
    Compare the first 50 lines or so of the sliced GCODE from one that works and one that doesn't.
    It may just be that the startup[ gcode needs a tweak. I haven't used the newer (2.x) Cura so I can't tell you exactly where that is :)

    ;Filament used: 4.92005m

    ;Layer height: 0.2

    ;Generated with Cura_SteamEngine 2.5.0

    M104 S200

    M109 S200

    ; -- START GCODE --

    ;-- end of START GCODE --

    ;LAYER_COUNT:240

    ;LAYER:-6

    M107

    Ignoring the commented out lines (ones that start with a ';' ) there is no real difference in these. the layer height is slightly different (the failing one is a thinner layer).

    I'd suggest trying a completely different slicer and see what happens.
