Using Auto Focus
1.
Turn machine
ON and wait for startup proce-
dure to complete.
2. Open top loading door and
move laser head
assembly
to easily accessible area.
3. Load flat, even workpiece onto table under
laser head assembly.
4. Press Z/U button on control panel to display
Z/U menu screen (see
Figure 44).
5. Use arrow nav buttons to highlight "Auto
Focus" and press Enter.
6. Table will raise until tip of auto focus sensor
contacts workpiece surface before lowering
to correct focal length.
7.
Focal length is now correctly set,
close top
loading door before beginning operations.
Setting Manual Focus
1.
Turn machine

lower table until distance between workpiece
surface and air nozzle is approximately 9mm.
Setting Focal Length
Focal length is the distance between the tip of the
laser head and the workpiece (see
Figure 43). It
must be set before every cutting/engraving opera-
tion for optimum laser performance.
IMPORTANT: Excessive/insufficient focal length
will diffuse laser beam output and cause weak
cutting/engraving results.
Note: For workpieces with varying height, it may
be necessary to manually focus separate cutting/
engraving operations for each height tier to main-
tain consistent focal length.
