Safety / Warning
It is important that you read this guide PRIOR to uncrating and setting
up the machine. There may be slight differences in the appearance or
features of your machine depending on the model that you purchased.
Laser safety glasses have been provided with your new machine. It
is extremely important that you observe all safety protocols when
operating the machine. Failure to do so can cause blindness or severe
personal injury.
-The working beam of the laser is INVISIBLE to the human eye
-ALWAYS wear Laser safety glasses when the laser is operating
-DO NOT place hands in the workspace when the laser is operating
-Both direct and indirect exposure to the beam can cause injury!

Component Identification
The image below identifies the major components of your new
machine. Please refer to this diagram when needed to complete the
setup instructions.
SFX model SFX-50GS
Uncrating / Unpacking
After removing the protective foam blocks and the Accessory Kit
from the crate you will find the rotary attachment (optional) bolted
to the work area of the work platform. If present, remove the four (4)
M6 Allen bolts holding it to the working platform and set it aside (the
needed Allen wrenches are in the Accessory Kit bag.
There are 4 screws that go through the working platform securing it
to the bottom of the crate, these need to be removed using a Phillips
head screwdriver. To accomplish this, carefully move the laser source/
controller off of the working platform so that all the screws are
accessible.
WARNING!
When uncrating and moving the machine it is critical that care is
taken to bend the umbilical between the laser source/controller and
the emitter/platform as little as possible. Any bend radius less than
20cm (7.8in) can damage the fiber optic cable that transmits the
laser beam from the source to the emitter module. The fiber optic
cable is a NON-REPLACEABLE item if it is damaged. Damage
from mishandling is NOT covered by warranty. If the fiber optic
cable is damaged, a new laser source and emitter module must be
purchased.
Once the laser source/controller and emitter/working platform are
moved to their permanent location proceed to the next steps for
preparing the machine for use.

Initial Setup Requirements
NOTE:
The ber laser marking machine is shipped with the emitter assembly
moved forward so the lens is not centered on the working space, this
is done to save space for shipping and protect it from damage. It will
need to be moved to center the lens over the working platform. This
will be covered in the “Aligning the Emitter Head” section after the
initial power up and connection to a PC since the red laser aiming
dot from the emitter head is required to position the emitter assembly
properly.
Accessory Kit
Inside the included accessory kit you will nd the following items:
-120VAC Power Cable (US) or 240V Power Cable (EU/UK)
-Grounding Wire
-Foot Pedal Switch
-USB Cable
-USB Thumb Drive (Software and instructional Videos)
-Laser Safety Switch Keys (2)
-Laser Safety Glasses
-Metric Allen wrench Kit
-Spare Jaws and chuck key for the rotary attachment (only if purchased
optionally)
Laser Marking Machine Connections
NOTE: A PC or Laptop with Windows 7/8/10 is required to
operate the machine.
Connect the USB cable, Power cable and Foot Switch to the back
of the machine via the ports that are labeled. The yellow lug on the
bottom is for an additional ground connection if a proper ground is not
provided by the power outlet that you have available via the third pin
[ground / earth] (Figure 1).

Driver Installation
Once connected to the machine, connect the USB cable to the PC, then
plug the machine into the AC power outlet and perform the following
steps:
-Plug the USB Thumb Drive into the PC (it contains the driver
software for the laser controller)
-Twist the Emergency Stop button clockwise, it will pop outwards and
the “Indicator Lamp” will light, this shows that the machine has power
-Remove the cap from the lens of the emitter (be careful not to touch
the lens with your ngers)
-Insert key into the laser safety switch and rotate clockwise, you will
hear the cooling fans for the laser source start and the secondary red
line focusing laser will light (optional, if equipped)
-On the PC, Navigate to the Control Panel > System and Security >
Administrative Tools > Device Manager, you will see the new device
listed under “Other Devices” (Figure 2)
Figure 2
Figure 3
You will be presented with a new window that asks you where to
locate the updated driver for the device, choose “Browse my Computer
for Driver Software”. The USB thumb Drive that was provided with
your machine will have the necessary software on it.
Figure 4
Before proceeding make sure that the USB Thumb Drive that was
provided is plugged into the PC, browse to it and select the main
Ezcad2.x.x folder and select it. Windows will look in the subdirectories
to locate the proper driver for the device (Figure 4).
When you nd the device
“USBLMCV2”, this is
the laser controller, right
click on it and choose
“Update Driver Software”
(Figure 3).
NOTE: the name of
the new device may
vary depending on
the controller that
your machine comes
congured with.

Once the driver is installed the Device Manager view will be updated
to show the Laser Control Board recognized by the system (Figure 5).

Software Setup (Ezcad)
“Installation” is not required to run Ezcad, it is a standalone program.
The best method is to copy the contents of the USB Thumb Drive
into a new folder on your desktop, and then create a shortcut to the
Ezcad executable. You can do this by locating the Ezcad executable,
right click and drag it onto the desktop. When you let go of the mouse
button a menu will appear, select “Create shortcut here”. Alternately
you can right click on the Ezcad executable and choose “Pin to
taskbar” to place it on your taskbar or “Pin to Start” to place it in the
Windows Start menu.
NOTE:
For Ezcad to operate in the Registered Mode the PC must be connected
to the laser with it powered on (the laser controller is the “Dongle”),
if the laser is not connected and powered up Ezcad can only be run in
trial mode which does not allow you to save any les from it.
Aligning the Emitter Head
As mentioned earlier in this document, the machine was shipped with
the emitter head moved forward over the working platform to save
space and protect it during shipping. It needs to be moved towards
the rear of the working platform to center the working area of the
emitter over the working platform. The following steps will help you
accomplish this.
1.Locate the center threaded hole in the working platform and insert
one of the M6 Allen head screws into it nger tight, this serves as an
easy reference to center of the working platform.
2.With the machine still powered up from the driver installation, open
the Ezcad application.
3.Place a shape in the working eld within Ezcad and keep it selected,
this will cause the red drawing laser in the emitter head to light.
You will notice that it is far forward from the center of the working
platform.
4.On the underside of the emitter head assembly there are four (4)
Allen head screws (Figure 6 “A”).
Figure 6
5.Using the included Allen wrenches loosen these slightly, only
enough that you can slide the emitter assembly backwards.
6.Slide the emitter head backwards until the dot from the red tracing
laser is aligned with the center hole in the working platform on the X
axis.

using the crank handle on the top of the supporting column.
oWhen moving up and down listen for the “loudest” noise being made
by the test material as it is being marked. As you move away from the
optimal focal point the noise from the test material will lessen.
*When ne tuning, listening for loudness, do this SLOWLY as the
optimum focal area range can be as small as +/- 0.25mm
-When the focal point is found, stop the marking process.
*Using the scale on the right side of the supporting column note the
number of mm indicated by the pointer.
*Subtract the thickness of the test material in mm from the number
indicated on the scale and this is your “zero” focal point from the lens
to the working platform (you may want to mark this on the scale with
a small dot using a Sharpie for future reference).
-If equipped, the optional second dot / line focus laser can be adjusted
if required to match the proper focal point by aligning it with the dot
from the tracing laser projected from the emitter lens.
*The optional second dot / line laser is aligned at the factory. Using
the manual focusing process helps verify that the setting was not
disturbed during unpacking and setup. If the setting was disturbed
during shipping, adjust the second dot / line focusing laser as required.
Determining the Optimal Focal Point
In order for your machine to provide the best results it is important
that it is focused properly. The emitter assembly can be moved up or
down to account for the thickness / height of the objects being marked.
The rst step is to nd the optimal focal point between the lens and the
working platform.
-Place a piece of test material on the working platform that is a known
thickness in millimeters (mm).
-Using Ezcad draw a 10mm square in the working area and then set
the following settings for the object
*Hatch 1
90 degrees, 0.01mm line distance
*Hatch 2 180 degrees, 0.01mm line distance
*Pen No. 0
Use default settings (50% power @ 75KHz)
-Click on the “Light” button (F1) and verify that the area that is going
to be marked is on the test material.
-Check the “Continuous” box, then the “Mark” button (F2)
-When the laser is marking, move the emitter assembly up / down
7.Once the emitter assembly is roughly on center, draw a square
the size of you scanning field in Ezcad and press the “Light” (F1)
button to have the red scanning laser project the square onto the work
platform. Using a square you can move the emitter assembly so that
one of the Sprojected X axis lines is perfectly square to the working
platform. The X axis is the most important since it cannot be adjusted
using the Ezcad software, only the Y axis can be adjusted via software.
8.Slightly snug the screws and recheck the alignment, if it is
satisfactorily aligned, tighten the 4 bolts.
NOTE:
This is also a good time to ensure that all screws between the main
emitter body and the emitter head are tightened down snugly (do not
overtighten) as they may have loosened slightly during shipping. If not
properly tightened you will see inconsistencies in marking.
Use of the Included Foot Pedal
When Ezcad is running, and the laser is powered on, the foot pedal can
be used to initiate marking whether or not the working area is being lit
by the red tracing laser. A single press of the foot pedal will begin the
marking process.
NOTE: The foot pedal can only be used to start the marking process, it
will not stop it.
