Receiving and
uncrating

gigabot®: unassembled 6
If you received a fully assembled Gigabot®, follow steps A1 through A5. If you received a
Gigabot® kit, follow steps A6 through A7. Follow steps A8 through A11 regardless of your
Gigabot® type.
For fully assembled Gigabots, need two 9/16" wrenches or socket wrenches to remove the
braces securing the Gigabot® to the base of its crate. You will also need a Phillips head
screwdriver to remove the panels of the crate.
Upon delivery of the Gigabot®, whether it is fully assembled or a kit, inspect all packages for
damage prior to signing for the delivery. If there is any damage, record it and report to our
shipping manager within 24 hours at [email protected].
For a video demonstration of these steps, feel free to watch our video on this process on our
YouTube channel at https://www.youtube.com/user/GigaBot3D/.
The Gigabot runs on 120V as a standard unless you specified when purchasing that it would
be preferable to use 220V. In the case that you ordered a 220V machine you will have to
acquire your own plug. The standard 120v version comes with a universal power cord.

If you are looking at the
front of your Gigabot (you
should see the Gigabot
nameplate) the power
switch is located on the
right side of your bot
closer to the front. It is a
small black circle switch;
flip it on!

bed level & z
home

quick start guide
12
Please follow the steps outlined in this guide to level the bed of your GB3+. Note that the
Gigabot® shown in these steps has blue tape as a printing surface (other Gigabots may have
Print in Z, Buildtak, or something else). Regardless of what surface is on the bed, the leveling
steps will remain the same.
These steps also use a business card as a feeler gauge between the nozzle and the bed.
Many business cards are about 0.01” or 0.3mm thick, which allows us to set a good Z home
position at the same time that we level the bed. Of course, users may opt to use real feeler
gauges as well. It is also acceptable to level the bed with something like a 1-2-3 block or a
piece of aluminum extrusion, but users will have to set the Z home position afterward.

Using the Viki LCD
controller, move the bed
down 150mm. Press
the button to see the
main menu, then select
“Prepare,” scroll down to
“Move Axis,” then “Move
1mm,” then “Move Z,”
and finally turn the wheel
clockwise until it reaches
150mm.
Using the 8mm
combination wrench,
loosen each of the 2
M5x12 hex head screws
that fasten the bed side
plate to the bed cross
rails. There are 8 in total.

These need to be loose
enough so that the ends
of the rails can move
vertically in the slots of
the side plates with little
to no resistance.
Adjust the leveling knobs
until there is about a 1/8”
gap (3mm) between the
top of the rail and the top
of the side plate at each
corner. A ruler or a shim
can be used to measure
this distance. Similarly,
users can opt to turn the
leveling knob to push the
rail up until it is flush with
the side plate, and then
lower it 4 full revolutions.

Repeat this process for
all 4 corners of the bed
frame.
Use the 8mm combination
wrench to lower the
M5x70 hex head screw
on upper Z limit switch
leveling block (when
looking directly at the
Gigabot® name plate, this
is the right side leveling
block). Turning clockwise
when viewed from above
will lower the screw. Do
2-4 full revolutions to
bring the Z home position
closer to the nozzle.

Using the Viki, select
“Auto Home Z,” in the
“Prepare” menu.
There should now be a
widened gap between
your nozzle(s) and the
surface of the bed. Push
the trolley to one corner
of the bed, near one of
the leveling knobs. If
the motors are locked,
they can be unlocked
by navigating to the
“Prepare” menu in the Viki
and selecting “Disable
steppers.”

Place a business card
between the nozzle and
bed. When viewed from
below, turning the knob
clockwise will raise that
corner. Turn the leveling
knob to raise the bed until
there is friction between
the nozzle and the
business card.
Repeat this process at all
corners of the bed. Using
the business card as a
feeler gauge, there should
be the same amount of
friction between the card
and the nozzle at each
corner.

b12
Use the 8mm combination
wrench to gradually
tighten the M5x12 hex
head screws at each
corner. Periodically use
the business card again
to check the level, since
tightening the hardware
on the rails may have
caused them to move
slightly. The bed cross
rails should be secured
and acceptably level to
the nozzle after 2-3 total
passes.
After the final tightening,
the bed will be securely
held in position and there
will be no need to re-level
unless some external
factor throws it out of level.

Loading
filament

quick start guide
20
Gigabot® prints with 2.85mm diameter plastic filament. Thanks to the all-metal design of the
hot ends, Gigabot users can print virtually any 3D printing filament available on the market!
The following section demonstrates how to load filament to Gigabot® prior to printing.
For a video demonstration of these steps, feel free to watch our video on this process on our
YouTube channel at https://www.youtube.com/user/GigaBot3D/.
Note that "magic T-nut" is the term we use for post-assembly drop-in T-nuts. Also BHCS is an
abbreviation for button head cap screw.
