    I've just taken apart my BB, and am now putting it back togeather. Somehow I've introduced a "spring" in the Y axis. Any pointers on what might be causing this?

    This can be caused by a slight misalignment of the Y rods. If they are wider or closer together on the backside then this happens.
    Loosen the screws of the mounts on the backend move the X axis to the back side.
    Also loosen the screws fixing the X rods so everything can align. Move the rods slightly in their mounts to remove any stress in the system.

    @Tim as @Alex9779 notes loosen everything up. I had similar issues, and that was what it was for me, I re-loosened everything and sort of gave it a knock and voila everything re-aligned. Had to do this after "the great Nylon incident" as stuff did get torqued a bit as well...

    The alternative is to print triangular things with the pointy parts towards the front of the bed... ;)
