Assemble the Y Assembly

Note that the Y assembly comes packaged with the aluminum build plate.

Remove the build plate for now, or it will be difficult to attach the bearings.

Partially pre-assembled build platform

Linear bearings (4)

4'' Zip ties

Thread all 4'' zip ties into the holes around the edges of all slots.

It's important the zip tie heads are on the bottom of the assembly.

Drop in the bearings.

Tighten with your hand first (it's fast.)

All the heads of the zip ties should end up on the bearings. (Else it's impossible to properly tighten the zip ties later.)

Tighten the zip ties with vise grips.

The proper tightening motion first pulls and stretches the zip tie upwards, and then pulls back.

Done.

Y Belt

4" zip ties

Y assembly

Make two loops at both ends of the Y belt.

The yellow marks will end up on the top of the loops.

Connect the two loops with another 4'' zip tie.

Make sure to have the tail of the zip tie pointing 'upwards'.

== Overview of the belt Installation ==

First, we attach the belt to the two outer-most holes.

Then we'll put tension on the belt connection with two more zip ties in the middle.

This makes the connection solid as a rock.

Attach the middle of the belt to the right-most hole on the acrylic platform.

Tooth-side of the belt should be facing away from the acrylic.

(The zip tie head position does not matter here.)

Tighten well with vise grip.

Strech the belt lightly across the cutout, and secure it to the left-most hole on the platform.

Tighten well with vise-grip.

Tension the belt by putting two more zip ties in the middle two holes.

Tighten these little by little, and alternate sides to get an even tension.

This would be the belt equivalent of 'cross-tightening' for screws.

When you pull the belt side to side, it should feel solid, with little play or movement.

(The two zip ties in the middle should have removed any slack from the connection.)

Done.

(Notice the zip tie tail still facing upwards.)
