ADVANCED SYSTEM OPERATION
Section 9-17
NOTE: If you are only using the Materials Database Tab and the
Auto Z feature on the UCP to run your projects there is no need
to follow any of the following focusing methods. These
methods should only be used if you use the Manual Control Tab
to print to the laser system.
Focusing Methods
The laser beam passes through the focus lens and converges to a small spot, called the focus point,
approximately 2 inches from the bottom of the focus carriage when using a 2.0 lens. In order to engrave
or cut properly with the laser beam, the material must be placed exactly at that focus point. To
accomplish this, the Z-axis engraving table needs to be moved up or down. There are three methods
used to focus the laser beam to the surface of the material, using the Focus Tool, using the Z -AXIS
POSITION display, or using AUTOFOCUS.
1. Focus Tool Method
Place your material into the upper left corner of the engraving field against the rulers. The material can
be placed anywhere on the table using this focusing method but for these purposes it’s being placed on
the upper left corner according to the values inputted on the MANUAL FOCUS POSITION on the System
Tab. Visually make sure that the height of the material will not interfere with the focus carriage when it
moves over the material. While on the main menu of the Keypad press the AUTO-FOCUS button once.
The focus carriage will automatically move to a predetermined position according to the MANUAL FOCUS
POSITION.
To move the table up or down, at a slow rate, move
the cursor to the hundreds decimal place (B) using the
RIGHT Motion Control button on the PLS keypad.
Press the UP or DOWN Motion Control buttons on the
PLS keypad to move the table up or down. To move
the table up or down, at a fast rate, move the cursor
back to the tenths decimal place (A) and use the UP
and DOWN buttons on the keypad to move the table.
After that is complete press the ESCAPE button to
return to the main menu.
The focus carriage will home back to the upper right corner. You should practice moving the table up and
down before using the focus tool.
Place the focus tool (4) on top of the material (1) and
position the focus carriage (3) directly above it. Raise
or lower the table so that the flat edge (5) the tool rests
against the front side of the focus carriage. Slowly
raise the table until you observe the tool either tilting or
sliding away from the focus carriage. This will occur
when the bottom edge of the focus carriage meets with
the top of the beveled edge (6) of the focus tool. The
objective is to stop moving the table at the point where
the tool just starts to move or tilt. The focal length (7)
distance should be approximately the length (in
inches) engraved on the front side of the focus
carriage. The standard and most common lens to use
is the 2.0-inch focal length lens.
After you have completed this method press the
ESCAPE button on the keypad. The focus carriage re-
homes back to the upper right hand corner.
