Grab your Z Axis Bearing Plate and your
two 8mm diameter chromed linear rods.
CAREFULLY slide the rods through the
openings in the linear bearing blocks. If
the rods seem hard to push through the
second bearing, you need to loosen the
screws fastening the linear bearing blocks
to the Z Axis Bearing Plate. Put tension
back on the screws that mount the linear
bearing blocks once you get the rods in. If
try to force these in or if you are not careful
sliding the rods through the bearing blocks,
you could push some of the ball bearings
out of the bearing blocks. If you accidently
push a couple out it’s not the end of the
world, however.
Now, lay the Z Axis Bearing Plate (with
the linear rods still in it, careful not to let
them slide out!) next to the X Axis Bearing
Plate. Study the orientations of these
plates shown in the above diagrams. We
should end up with the Z Plate in front of
the X Plate with these same orientations
shown. Let’s do that now.
Work with the X Axis Bearing Plate laying
on the table, face up. Keeping in mind the
required orientation of the plates, slide in
the bottom of the rods that are in the Z
axis linear bearings into the bottom rod
supports that you’ve already installed on
the X Axis Bearing Plate. As soon as you slide the bottom of the linear rods into the bottom rod
supports, slide the top two rod supports onto the top of the rod. On just the bottom rod
supports, tension the Allen head bolt that clamps the rod support to the rod. Now install M5x16
machine screws into the mounting holes for the top rod supports, through the top (G) holes on
the X Axis Bearing Plate, and begin to snug them up using an M5 flat washer and M5 Nylock nut.
Now run the left most M5 screw through the free loop of the spring, and snug it down. Make
sure the rods are parallel and the two rod supports are even in terms of their position on the X
Axis Bearing Plate before you put a final torque on these mounting and tension screws.
