Power and Inputs
A. USB Port—This port allows you to load and save designs and parameters
directly onto the engraver.
B. USB Line Port—This port connects to your control computer and its
engraving software using any of its USB ports.
C. Ethernet Port—This port connects to your control computer and its
software either directly or via the internet.
D. Control Panel Switch—This switch turns on the power supply to your
engraver's control panel.
E. Laser Power Switch—This switch controls the power supply to your
laser tube. Turn it on after the water system and control panel.
Right Access Door
A. X-Axis Driver—This device moves the laser head along the X rail.
B. Y-Axis Driver—This device moves the X rail along the Y rail.
C. Mainboard—This circuit board controls the engraving process,
responding to commands from your engraving software or the machine's
control panel.
D. Control Power Supply—This device powers the machine's control panel.
E. Laser Power Supply—This device transforms standard electricity into
the extremely high voltage charge necessary for the laser tube.
Laser Power Supply
A. High-Voltage Wire—This line is connected to the laser tube's anode or
positive end, providing high-voltage current to power the laser.
B. Mounting Holes—These standard slots allow simple installation and
removal.
C. Digital Display—This display provides the real-time current to the laser
tube in milliamps and notification of any problems with the laser or water
systems.
D. Laser Indicator Light—This light shows when current is being sent to
the laser tube.
E. Main Power Terminal—This terminal block holds the power supply's
connection to the engraver's grounding (FG) and to the main power
supply (AC).
F. Test Button—This button is used to attempt to test fire the laser when
trouble-shooting problems. If the laser fires successfully, the problem will
usually be with the control panel or its connections.
G. Connection Terminal—This terminal block holds the connections to the
high (H) and low level output (L), the water protection switch (P), another
ground (G), and two laser signal controls (IN & 5V).
H. Water Indicator Light—When connected, this light shows the water
cooling system is operating.
I. Laser Signal Indicator Light—This light shows the laser tube is
operating.
J. Ethernet Port—This port allows you to connect the laser power supply
to an external ammeter.
