Main Parts
A. Cover—The cover provides access to the main bay for placing and retrieving materials, as well as fixing the laser
path alignment and other maintenance. Power to the laser is automatically cut when the cover is opened.
B. Viewing Window—The polycarbonate window is shielded to protect you and others from the laser and its
reflection, allowing monitoring of the engraving process. However, you should never stare continuously at the
laser during operation, even through the window.
C. Y-Axis Rail—The Y-axis rail supports the movement of the X-axis rail up and down the workbed.
D. X-Axis Rail—The X-axis rail holds the 2nd mirror and LED lighting. It also supports the movement of the laser
head left and right across the workbed.
E. Workbed—The workbed can be adjusted in height to fit thinner and thicker materials, as well as adjusted between
the aluminum and honeycomb platforms.
F. Laser Head—The laser head holds the 3rd mirror, the focus lens, the red dot guidance, and the air assist outlet.
G. Workbed Adjustment Knob—This knob allows manual raising and lowering of the workbed along the Z-axis.
H. Control Panel—The control panel offers hands-on control of the engraving process, including manual movement
of the laser head and firing of the laser.
I. Emergency Stop—This button immediately cuts all power to the laser tube in the event of an emergency.
J. Warnings—These notices supplement the Safety Information chapter of this manual. Read them carefully before
using the machine.
K. Front Pass-Through Door—This door opens to allow larger pieces of material to be fed through the workbed.
Additional care must be taken to avoid seeing or suffering exposure to the laser beam and its reflection.
L. Front Access Door—This door provides access to the area below the workbed for easy cleanup. This is also
where the accessories pack is located when the engraver first arrives.
M. Power and Inputs—This panel includes the machine's power switches as well as the ports for its USB, computer,
and internet connections.
N. Right Access Door—This door provides access to the mainboard, motor drivers, and power supplies.
O. Power Sockets—These sockets connect to your main power supply, ground the machine, and provide an
additional socket for your water pump if needed. It is recommended, however, to use a separate plug on a different
fuse for your water cooling system.
P. Top Rear Access Door—This door opens to the laser bay, holding the laser tube and its connections.
Q. Laser Tube—This long glass tube is filled with helium, nitrogen, and CO₂ gas and water cooled to safely produce
your engraving laser. Its connection to the laser power supply is extremely high voltage and extremely dangerous.
R. Rear Pass-Through Door—This door is the rear equivalent of the front pass-through door and requires similar
care during use.
S. Lower Left Rear Access Door—This door provides access to the same area as Door N above.
T. Lower Rear Access Door—This door provides access to the air pump for easier maintenance.
U. Exhaust Fan—This fan pulls out gases and airborne debris from the worktable, sending it through your vent to
a window or air purifier.
V. Water Ports—These ports connect to your water pump or chiller to keep your laser tube cool and stable.
W. Air Intake—This port connects to your air assist to provide its pressurized air. Periodically check its filter to
keep it clear of any obstruction.
