THANK YOU FOR PURCHASING THE FILAMENT DETECTION
RETROFIT KIT FROM re:3D Inc.®!
REFERENCES & HELPFUL DOCUMENTS :
VIDEO INSTRUCTIONS :
This upgrade will let your Gigabot® automatically detect when your filament has run out. It
will respond by pausing the print and waiting for the user to manually replace the filament
and resume the print. You will find that this is especially helpful for saving prints, reducing
wasted filament, and saving time and eort in completing full print jobs.
Some external resources may be helpful during the assembly process. For example,
knowing the correct names for dierent parts on the Gigabot®, or proper use of certain
tools. Resources that we thought may be helpful have been linked to at the end of this
guide.
If you prefer a video guide, please search for “re3D Tech” on YouTube and find our “Filament
Detection Installation” video.
introduction

READ INSTRUCTIONS : All the safety and operating instructions should be read before the printer is
operated.
RETAIN INSTRUCTIONS : The safety and operating instructions should be retained for future reference.
HEED WARNINGS : All warnings on the product and in the operating instructions should be adhered to.
FOLLOW INSTRUCTIONS : All operating and use instructions should be followed.
CLEANING : Unplug this product from the wall outlet before cleaning. Do not use liquid or aerosol
cleaners.
ATTACHMENTS : Do not use attachments or enhancements not recommended by the product
manufacturer as they may cause hazards.
WATER AND MOISTURE : Do not use Gigabot near water - for example, near a bath tub, wash bowl,
kitchen sink, or laundry tub, in a wet basement, or near a swimming pool, and the like.
PLACEMENT : Do not place this product on an unstable cart, stand, tripod, bracket, or table. The
product may fall, causing serious injury to a child or adult, and serious damage to the product. Use only
with a cart, stand, tripod, bracket, or table recommended by the manufacturer, or sold with the product.
Any mounting of the product should follow the manufacturer’s instructions, and should use a mounting
accessory recommended by the manufacturer.
VENTILATION : Slots and openings in the cabinet are provided for ventilation and to ensure reliable
operation of the product and to protect it from overheating, and these openings must not be blocked
or covered. The openings should never be blocked by placing the product on a bed, sofa, rug, or other
similar surface. This product should not be placed in a built-in installation such as a bookcase or rack
unless proper ventilation is provided or the manufacturer’s instructions have been adhered to.
POWER SOURCES : This product should be operated only from the type of power source indicated on
the marking label. If you are not sure of the type of power supply to your home consult your appliance
dealer or local power company. For products intended to operate from battery power, or other sources,
refer to the operating instructions.
GROUNDING OR POLARIZATION : This product may be equipped with either a polarized 2-wire AC
line plug (a plug having one blade wider than the other) or a 3-wire grounding type plug, a plug having
a third (grounding) pin. The 2-wire polarized plug will outlet, try reversing the plug. If the plug still fails
to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the
polarized plug. The 3-wire grounding type plug will fit into a grounding type power outlet. This is a
safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your
obsolete outlet. Do not defeat the safety purpose of the grounding type plug.
POWER-CORD PROTECTION : Power-supply cords should be routed so that they are not likely to
be walked on or pinched by items placed upon or against them, paying particular attention to cords at
plugs, convenience receptacles, and the point where they exit from the product.
LIGHTNING : For added protection for this product during a lightning storm, or when it is left unattended
and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable
system. This will prevent damage to the product due to lightning and power-line surges.
OVERLOADING : Do not overload wall outlets, extension cords, or integral convenience receptacles as
this can result in a risk of fire or electric shock. A product and cart combination should be moved with
care. Quick stops, excessive force, and uneven surfaces may cause the product and cart combination
to overturn.
OBJECT AND LIQUID ENTRY : Never push objects of any kind into this product through openings as
they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock.
Never spill liquid of any kind on the product.

FIRMWARE NOTE
Installing this upgrade will require a firmware update for your
Gigabot’s® Azteeg. This manual only includes instructions for
installing the physical components. Please refer to our wiki (wiki.
re3d.org) for instructions in updating firmware.
Filament detection is only active while the associated hot end is also
active.
When filament detection is triggered during operation:
• Extruder perforams a small retraction
• Bed lowers slightly
• Print head moves to the front and center of the Gigabot®
• Extruder performs a long retraction
• Hot end heater is automatically turned o, while the bed heater
remains on
• User must remove remaining filament from the filament tube
• Then insert new filament into filament tube
• Press center button on Viki (this will turn the hot end heater back
on)
• Once hot end is up to temperature, click center button again to
activate extruder
• Rotating the Viki wheel engages the extruder feed. Feed filament
until extrusion is verified
• Click center button to resume print

BEFORE YOU BUILD
it’s hip to be square!
the uses of grease
When assembling the
Gigabot®, it is essential to
work on a flat surface and to
carefully square perpendicular
parts as much as possible.
This is especially important
while assembling the side
plates, Z-axis uprights and
vertical common rails, bed
frame, upper and lower cross
rails, and bridge assembly.
Use large clamps to help
square up frames if needed.
Make good use of grease
during assembly. These
will help hold the eccentric
spacers when installing the
V-groove wheels and also
keep them from damaging
the side plates or end trucks
during adjustment. Likewise,
it will ensure smooth, quiet
operation when applied the
the Z-axis ACME threaded
rods.

t-nuts, how do they work?
Measuring and marking
T-nuts are an essential part
of assembling the Gigabot®.
These are inserted into the
aluminum extrusion in order
to fasten parts to the frame.
Post assembly T-nuts are
also used. These hold their
positions well without sliding
around, and are useful when
installing retrofits.
There may be parts of the
instructions that suggest
marking spots on the
Gigabot® to properly place
parts. When marking, be sure
to only use a pencil--using a
permanent marker will leave
unsightly marks on the metal!
