Method 2: Using the Ruler
a. Use the provided ruler to measure the distance from the center line of the scanning head to
the surface of the test material.
b. Rotate the focus adjustment knob clockwise to lower the scanning head or rotate it
counterclockwise to raise the scanning head until the height on the ruler is the same as the
value marked on the lens head, which varies among different models.
5.2.3 Preparing Your Design
1. Make sure the control computer is connected to the machine via the USB cable.
If you previously disconnected the control computer, reconnect it via the USB cable now.
If your computer is already connected and EZCad is already running, restart it now to establish
a connection between the computer and the laser's control board.
2. Double click EzCad2.exe in the "Software" folder in the USB
drive to start the software.
3. Load or create a design in EZCad as follows.
Here we only provide a brief introduction on drawing bitmap pictures and vector graphics and
creating text. For detailed parameter descriptions and settings, see the EZCad software manual
in the USB drive.
