The following is a list of common definitions, terms and phrases used throughout this manual as they relate
to this 3D printer and 3D printing in general. Become familiar with these terms for assembling, adjusting or
operating this machine.
Glossary of Terms
Axis: Direction of movement. Three geometric
axes are typically X (left-right), Y (front-back) &
Z (up-down). In addition, G-code for 3D printers
has an E-Axis than describes the length of fila-
ment that moves through the extruder.
Bowden Tube: A flexible tube that guides fila-
ment from the feeder to the print head. Bowden
tubes are used in Bowden extruders, in which
the feeder is not directly mounted to the print
head.
Build Plate: A flat surface where the printer
deposits molten filament.
CAD (Computer-Aided Design): CAD software
is used to create a digital model of a project.
Extruder: The mechanism that pushes and pulls
filament and deposits it on the build plate,
including the feeder, heating elements, and
nozzle.
FFF (Fused Filament Fabrication): A 3D printing
process in which filament is extruded through a
heated print head and deposited on the object
being printed. Also known as FDM (fused
deposition modeling), a trademarked term for
the same process.
G-Code: A machine language that uses axis
points and commands.
Home Position: A fixed point on the machine set
with proximity switches. It is the zero point for
X, Y, and Z axes.
Hot End: The heated portion of the extruder
including heat sinks, heating block, and nozzle.
Infill: The interior material of a 3D printed object.
Can often be printed at a lower density than
the shell.
Nozzle: The component that funnels molten
filament out of the print head, usually made
of brass. The nozzle diameter determines the
width of extruded filament.
PLA: A popular material used for 3D printer fila-
ment because it is non-toxic, affordable, and
prints at a low temperature. It is often the first
choice for rapid prototyping.
Print Head: The assembly of components from
which filament is extruded. Often moves along
all axes, although in some printers the build
plate also moves.
Print Speed: Speed at which axis movement
occurs, typically measured in mm/s.
Resolution: Often referred to as "build resolution"
or "print resolution." It is the height of each layer
of printed material.
Support: Extra material printed in order to allow
overhangs and intricate geometry. Supports
are typically printed at low density and can be
removed from the object after printing.
Shell: The exterior surface of a 3D printed object.
Typically the first part of each layer to be
printed.
Slicer: Software that converts 3D models into
G-code by "slicing" the model into many layers
of movement commands.
STL: A common file type used to create and store
3D models.

NOTICE
Safety Instructions for Machinery
SECTION 1: SAFETY

-10- Model G0923 (Mfd. Since 05/20)
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate-
rial. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica-
tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement dur-
ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec-
ommended accessories. Using improper acces-
sories will increase the risk of serious injury.

consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre-
cautions are overlooked or ignored, serious
personal injury may occur.

-12- Model G0923 (Mfd. Since 05/20)
SECTION 2: POWER SUPPLY
Availability
Before installing the machine, consider the avail-
ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
Electrocution, fire, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
Full-Load Current Rating
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
Full-Load Current Rating at 120V ....... 6 Amps
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup-
ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
120V Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage .................... 110V, 115V, 120V
Cycle ..........................................................60 Hz
Phase ........................................... Single-Phase
Power Supply Circuit ......................... 15 Amps
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.

Model G0923 (Mfd. Since 05/20) -13-
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon-
nect it from power, and immediately replace it with
a new one.
Extension Cords
We do not recommend using an extension cord
with this machine.
If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size ...........................16 AWG
Maximum Length (Shorter is Better).......50 ft.
Grounding & Plug Requirements

SHOCK HAZARD!
Two-prong outlets do not meet the grounding
requirements for this machine. Do not modify
or use an adapter on the plug provided—if
it will not fit the outlet, have a qualified
electrician install the proper outlet with a
verified ground.
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!

NOTICE
If you cannot find an item on this list, care-
fully check around/inside the machine and
packaging materials. Often, these items get
lost in packaging materials while unpack-
ing or they are pre-installed at the factory.
This machine was carefully packaged for safe
transport. When unpacking, separate all enclosed
items from packaging materials and inspect them
for shipping damage.
If items are damaged

SECTION 4: OPERATIONS
Operation Overview
The purpose of this overview is to provide the nov-
ice machine operator with a basic understanding
of how the machine is used during operation, so
the
machine controls/components
discussed later
in this manual
are easier to understand.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual,
seek additional
training from experienced
machine operators
, and do additional research
outside of this manual by reading "how-to" books,
trade magazines, or websites.
To complete a typical operation, the operator
does the following:
1. Creates or downloads 3D model.
2. Uses slicer software to prepare .GCODE file,
then loads file onto SD card.
3. Ensures build plate is clean and level.
4. Applies adhesive to build plate.
5. Preheats nozzle.
6. Loads filament into machine.
7. Starts print.
8. Removes model from build plate when print is
complete.
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any proj-
ects. Regardless of the content in this sec-
tion, Grizzly Industrial will not be held liable
for accidents caused by lack of training.
To reduce risk of machine
damage and injury, read
this entire manual BEFORE
using machine.
