    My method relies on 123 blocks (cheaply purchased off amazon). However, some other item that is metal and a consistent thickness, can be used.

    All of this should be done before the belts are installed, or with the belts loose.

    At this point, you should have both of the X Carriages touching the 123 blocks, or you should be within 1-2mm on one while the other is touching.

    Now you can go about installing the belts.

    This procedure should get your Y rail aligned correctly and fairly easily once you get the knack of adjusting the tension.
