Aligning the X Carriages & Y Rail

FIRST DRAFT - mandalarose

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.

Installing the Belts

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.
