Y AXIS STAGE ASSEMBLY
Locate the Y Axis Bearing plates and (8) of the V wheels that you assembled in the last step.
Grab one of the V wheels and one of the Y Axis
Bearing Plates. Install an M5 bolt through one of
the holes indicated in the picture to the right.
Now install a non-adjustable 6.35mm (quarter inch) spacer on the opposite side of the plate,
sliding it over the threads of the bolt. Install an assembled V Wheel onto the threads of the bolt,
then tighten it down using an M5 nylock nut.
Using an Allen wrench or Phillips screwdriver
(depending on if your kit came with allen or phillips
head M5 screws) and 8mm socket, get these snug
now. Don’t torque too much, just a bit of tension is
fine. If you are straining as you tighten, it is FAR too
tight! The wheel should still turn fairly freely once
tightened. If it’s really hard to spin, back off the nut
a tad. Install another V wheel the same way in the
other hole indicated by the arrow.
Now, take an eccentric spacer and put it in one
of the holes opposite those installed that you just
installed. Spin the eccentric spacer in that hole
and observe how the bolt hole in the spacer gets
closer then farther away from the V wheel kits
that you already installed. This will allow you to
snug up the bearings to the V rail after installing
them. Leave the eccentric spacer in its loosest position (bolt hole farthest away from the other
bearings). Now run an M5 socket head bolt through the plate, then the spacer, then install a V
wheel and loosely install an M5 nylock nut. You should end up with the bolt head, then Y Axis
Bearing Plate, then eccentric spacer, the V wheel, then an M5 nylon nut. Do NOT tighten these
very much yet because you will need to be able to spin the spacer soon. Install another
eccentric spacer and V wheel in the other hole just like you did this one.
Repeat these steps to install the V wheels on the other Y Axis Bearing Plate. Keep the assembled
Y Axes Bearing Plates nearby.
Locate both 2020 V rails as well as the front frame piece (long rectangular piece with four holes in
the middle). Notice the small half circle notch at the bottom of this piece. If that notch is at the
bottom left, then you are looking at the front side of the piece. Check out the middle picture on
page 22 to see the correct orientation of this piece when installed.
