How it Works
With the Dual Head installed, the special "Beam Splitter" optic inside of the Dual Head splits the laser
beam in half. It reflects one half of the laser beam's energy down through the focus lens inside the Dual
Head and passes the other half of the laser beams power through the beam splitter. The laser beam
goes through the beam tube and then onward through to the single heads #3 mirror where the laser beam
is reflected downward through the single head's focus lens.

By splitting the laser beam's power in half, you effectively get approximately 50% of the power at the Dual
Head and 50% at the single head. However, since the beam splitter absorbs some energy, and there are
other losses involved, getting an exact 50/50 split is not possible, but the difference in most applications,
is negligible.
Installation
NOTE: The example below assumes that you have also purchased the Air Assist option. If you do not
have the Air Assists option, please ignore any references to the "cone(s)" or "air hose" as these two items
are the only differences between the regular Dual Head and the Dual Head with Air Assist option.
•
If your laser system is not ON right now, turn it ON .
•
Using the menu control keys, select the "Dual Head" option in the "Options" section of the
"Preferences" menu. The display will ask you to confirm your choice so respond "Yes". It will then ask
you to "Turn system OFF ", then "Wait 15 seconds", and then "Turn system back ON ". You should do
this except you should install the Dual Head BEFORE turning the system back ON .
•
The Dual Head will be installed to the
left side of the single head. Pick up
the Dual Head assembly and note that
the lower X-axis bearing pivot arm
should be in about the 10 o'clock
position (from the backside view, and 2
o'clock from the front side. Starting with
the Dual Head rotated about 30-45
degrees clockwise and tilted
towards you slightly, position the lower
X-axis bearing in the lower bearing track
of the X-axis rail. Gently pull up on the
Dual Head while turning it counter-
clockwise back to the 0 degree position and "hooking" the top two X-axis bearings into the upper
bearing track of the X-axis rail.
•
Verify that all three bearings are in their respective track. Gently push the carriage to the left and
then back to the right. It should roll smoothly, if not, verify and/or re-install the Dual Head.
