Attach Smooth Idler Wheels
These wheels ensure that the belt is held tightly against the motor pulley once they are installed. They are installed with aluminum spacers as they need to be aligned with the center of the makerslide rails.

Note: If you purchased the Belt Kit Upgrade, you will follow the same steps but with the upgraded hardware and stepper motors. The complete Upgrade Belt Kit instructions can be found here.
To attach the smooth idler wheels, begin by putting an M5x30 bolt through the appropriate hole on the plate. Slide an aluminum spacer onto the bolt.

Repeat this for the other plate. You should now have two mirrored plates that look like this:
