    parts are printing at angle, help!!!!

    parts are printing at an angle in the Y axis i have checked the belts and the motor does not seem to be loosing steps, i have calibrated it over and over and its dead on every time, it always comes back to the same spot. I used two different slicers checked the gcode for anything out the ordinary and nothing. its consistent though, the y moves back just a hair each layer in the y axis but does not show any signs of doing so in calibrating. any help with this problem will be rewarded with life long happiness and a greater understanding of the universe, thanks.

    You are layer shifting, and as you have stated it is shifting the Y axis only.

    Here are a few things that can cause this layer shifting.
    Smooth rods are not parallel and binding.
    Smooth rod lubrication is sticky causing layer shift.
    Stepper motor current is not adjusted correctly.
    Linear bearings have not been cleaned of there factory packing and lubricated.

    Below is a sample of how dirty factory packed bearings can be.
