There are two main steps in this section: Installing the bed frame to the Gigabot®, and then installing
the bed plate.
overview

gigabot®: unassembled 144
Work on a flat surface.
Take the time to properly align and fasten the nut cups to the
bed side plates. This will ensure smooth movement of the bed
as it goes up and down.
Align the left edge (looking from the front) of the bed plate with
the pencil marks on the bed cross rail to properly position it on
the bed frame.

You will now install the
bed frame and then the
bed plate on top of that.
First, check that the
threaded rods are
securely seated inside the
bearings of the bearing
blocks.
If they are not seated,
press them into the
bearing before continuing
on.

Repeat H2-H3 on the
other side.
Place an object in the
middle to hold the bed
frame. Here, we use a box
that is placed diagonally
for more stability.
Without using a prop to
hold the bed frame, the
lower side plates will
interfere with installing
the remaining wheels to
secure the bed frame to
the Z-Uprights.

Here, the bed frame
Panduit has been
oset from center to
accomodate the box that
will prop it up.
Carefully lower the bed
frame down into the
Gigabot® frame.
Place the bed frame on
top of your prop, which
each of the bed frame
wheels resting against the
Z-uprights.

Apply grease to the outer
edge of one of the holes
near the rear of the bed
frame. Insert the eccentric
spacer here such that the
mark (thinnest side) is
facing away from the rail.
Insert a M5x30 BHCS into
a V-groove wheel. Apply
grease along the screw
threads and insert it into
the eccentric spacer. It is
easier to place the wheel
onto the rail and then
insert the screw, as shown
on the right.
Place pressure on the
rear of the bed frame and
insert the M5x30 BHCS
through the wheel and
spacer.

Place an M5 flat washer
on the screw.
Fasten an M5 lock nut
onto the same screw and
fasten this into place using
an 8mm wrench and 3mm
Allen Key. Refer to the bed
frame assembly section
for other examples of
fastening the wheels.
You have now secured
the bed frame onto one of
the rear Z-Uprights.

Repeat H10-H14 for the
wheels in the front of
this same side of the
bed frame. Again, the
eccentric spacer should
be positioned such that
the mark (marked on the
thinnest side) faces away
from the rail.
If the eccentric spacer is
dicult to insert into the
bed side plate, it may be
pressed into place with
the help of pliers.
Insert another V-groove
wheel in the same way as
in H12.

Place an M5 flat washer
and M5 lock nut on the
M5x30 BHCS and fasten
the wheel into place with
an 8mm wrench and 3mm
Allen Key.
You now only need to
fasten one more V-groove
to secure this side of
the bed frame to the
Z-uprights.
Repeat H10-H14 for the
remaining wheel on this
side of the bed frame.

You have now completed
fastening wheels to one
side of the bed frame.
Next, you will add the
remaining wheels to the
other side of the bed
frame.
Apply grease and insert
an eccentric spacer into
the rear hole in the same
way as H10.
Insert a V-groove wheel
here in the same way as
H11-H12. Place an M5 flat
washer and M5 lock nut
on the M5x30 BHCS.

Fasten the wheel into
place using a 3mm Allen
Key and 8mm wrench as
in H14.
Repeat steps H16-H21 to
fasten the remaining 2
V-groove wheels to the
bed frame. This will mostly
secure the entire bed
frame to the Z-uprights.
Make sure the nut cups on
each side of the Gigabot®
are positioned such that
the threaded holes are
facing inward. Again, do
this for both nut cups!

Hold the bed frame up
and remove the prop from
below it.
Gently lower the bed
frame until it sits on top of
the Z axis motors.
At first, the bed frame may
rest on top of the nut cups
themselves, but carefully
work the frame in between
the two nut cups and let it
sit on top of the motors.
The nut cup will likely not
be aligned with the bed
side plate holes yet.

H31
H32
H33
Check that the bed frame
is resting directly on top
of the Z motors on both
sides.
Since the rear bed
frame wheels use round
spacers, they need to be
pressed against the rail
when tensioning the other
wheels to ensure the most
secure fit.
Starting on the right side
of the bed frame, apply
pressure to the rear of
the bed frame against
the Z-upright and use the
8mm wrench to gradually
turn the eccentric spacer
counter-clockwise. This
tightens the wheel against
the rail.

H36
After each gradual
rotation, check that the
wheel is making good
contact with the rail,
yet can still be spun in
place by hand. Continue
adjusting the wheel until
this condition has been
met.
On the same side of the
bed frame, repeat this for
the front wheels. Here,
the convention is to turn
the wheel towards the
horizontal center of the
bed side plate to tighten,
and turn away from it to
loosen.
Check the wheels in
the same fashion as in
step H34 and adjust as
needed.

This was alluded to in
H33-H35, but for the
center wheels on the
right-side bed side plate,
the convention to tighten
is to turn them towards
the vertical center of the
plate (as opposed to the
horizontal center).
Repeat steps H33-H37 for
the opposite side of the
bed frame.
After performing the
tensioning on all of the
wheels, move the bed
frame up and down along
theZ-uprightsandperform
the same check as in H34
at dierent locations and
adjust as necessary.

The bed frame should be
able to freely travel along
the entire length of the
Z-uprights. If you release
the bed frame, it should
fall straight down from its
own weight. If you check
this, be ready to catch it
from below--don’t let it
crash and get damaged!
There are MXL belts that
connect the pulleys on
the Z motors and ACME
threaded rods. Turn the
belt by hand to align the
nut cup with the holes in
the bed side plate.
Once the nut cup holes
are aligned with the holes
in the bed side plate,
fasten them together
using 2 M5x12 BHCS and
a 3mm Allen Key.

Repeat this alignment and
fastening process with
the other nut cup as well.
The bed frame is now
properly secured into the
Gigabot® frame.
Next, you will make marks
on the bed frame to help
with the placement of the
bed.

On each bed cross rail,
make a mark 3 3/16” from
the left most edge of the
bed side plate.
Slightly loosen the M5x8s
securing the 4 bed angles
to the bed cross rails so
that they can move freely
along the rails.
The following several steps
are something we do in-
house to assure that the
bed angles are properly
aligned and also fastened to
the bed cross rails without
becoming skewed. Place
the bed plate metal side
down onto the bed frame
and align the left edge with
the marks made previously.
