Step 5: Y-Axis Supports

To build the y-axis assembly, we can take cues from the z-axis build. Essentially, it's the same process. This video will show the two sides of the y-axis, which in part will control the z-axis motion, and the y-axis rail support.

Quick Steps:

1. Get a piece of board that will serve as the y-axis rail support. The length will be determined later when we build the gantry. Anticipate the gantry width and cut the piece about 5" longer to have wiggle room.
   
2. Chamfer the edges to accommodate the aluminum angle.
   
3. Measure and cut for the two sides (actually, it's the upper and lower pieces).
4. Cut grooves for the linear bearings on both sides.
5. Assemble, test and measure for the back support.
