Model G0911–G0914 (Mfd. Since 05/21)
The following is a list of common definitions, terms, and phrases used throughout this manual as they relate
to this CNC laser and laser cutting in general. Become familiar with these terms for assembling, adjusting,
or operating this machine. Your safety is
VERY important to us at Grizzly!
Anode: The positive (+) terminal, electrode, or
element of an electron tube or electrolytic cell.
Axis: Direction of movement. On a typical three-
axis machine, axes are X (left to right), Y (front
to back) & Z (up and down). Axis directions
are described as positive or negative. On this
machine, negative movement is defined as
movement towards the front (Y), left (X), and
downward (Z) portion of the working envelope.
CAD (Computer Aided Design): CAD software
is used to create a digital model of a project.
CAM (Computer Aided Manufacturing): CAM
software converts CAD models into a toolpath
defined by code that CNC machines interpret.
Cathode: The negative (-) terminal, electrode, or
element of an electron tube or electrolytic cell.
CNC (Computer Numerical Control): Automated
operation of a machine by a computer program
via written instructions.
ESD (Electrostatic Discharge): A sudden flow
of electricity between two electrically charged
objects caused by contact, an electrical short,
or dielectric breakdown.
Focal Length: The distance from the focal point
of a lens or mirror to the corresponding princi-
pal plane.
Frame Slop: Machine error code that indicates
travel exceeds working envelope of X- and
Y-axes.
Home Position: Machine designated zero point
on all axes.
Name Over Lap: Machine error code which
indicates file with same name is detected in
destination memory location.
Origin: User designated zero point for a workpiece
from which laser will reference positioning of all
cutting/engraving.
Profile Toolpath: A toolpath that cuts around or
along the profile of a set of vectors. Typically
used to cut out the shape of a design.
Right-Hand Rule: A rule that uses the shape of
the right hand to establish the standard orien-
tation of vector quantities normal to a plane.
Soft Limits: Axis limits imposed by workspace
boundaries based on controller settings and
the location of home.
Stepper Motor: An electric motor (typically DC)
that moves in precise steps when pulses are
received. Has very accurate positioning and
speed control.
Thermal Lens Effect: When energy from a laser
beam passing through a sample is absorbed,
causing heating of the sample along the beam
path.
Toolpath: User-defined route that the laser fol-
lows to cut or engrave a workpiece.
Track/Frame: Machine command which veri-
fies toolpath boundaries of loaded image do
not exceed available working envelope of
workpiece.
Working Envelope: Total area that laser tip can
travel within that does not exceed physical
machine boundaries.
XSlop Over: Machine error code that indicates
travel exceeds working envelope of X-axis.
YSlop Over: Machine error code that indicates
travel exceeds working envelope of Y-axis.
