OWNER'S MANUAL

(For models manufactured since 05/20)

This manual provides critical safety instructions on the proper setup,

operation, maintenance, and service of this machine/tool. Save this

document, refer to it often, and use it to instruct other operators.

Failure to read, understand and follow the instructions in this manual

may result in fire or serious personal injury—including amputation,

electrocution, or death.

The owner of this machine/tool is solely responsible for its safe use.

This responsibility includes but is not limited to proper installation in

a safe environment, personnel training and usage authorization,

proper inspection and maintenance, manual availability and compre-

hension, application of safety devices, cutting/sanding/grinding tool

integrity, and the usage of personal protective equipment.

The manufacturer will not be held liable for injury or property damage

from negligence, improper training, machine modifications or misuse.

Some dust created by power sanding, sawing, grinding, drilling, and

other construction activities contains chemicals known to the State

of California to cause cancer, birth defects or other reproductive

harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you

do this type of work. To reduce your exposure to these chemicals:

Work in a well ventilated area, and work with approved safety equip-

ment, such as those dust masks that are specially designed to filter

out microscopic particles.

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.
