and passes the other half of the laser beam through the beam splitter. The second half of the laser beam then
travels through the beam tube and is deflected by the primary carriage mirror and through the focus lens.
Installation
Note: The example below assumes that you have also purchased the Dual Head Air Assist option. If you
do not have the Dual Head Air Assist option, ignore the section on Dual Head Air Assist installation. Also
keep in mind that backsweep fittings are not compatible with the dual head option.
1. Examine the Dual Head carriage and note that single lower bearing assembly on the carriage is attached
to a spring loaded pivot arm.
2. Install the dual head carriage on the X axis rail to the left of the primary carriage by engaging the lower
wheel in the lower V groove of the rail as shown and pulling up on the carriage to rotate the spring loaded
pivot arm enough to slip the upper wheels over the top of the rail and into the upper V groove.
3. Verify that all three bearings are in their respective grooves in the X rail and gently roll the carriage back
and forth on the rail to ensure that it rolls smoothly.
