InFocus Laser Platform M-300 - Manual (Page 49)

3-24 System Operation
The AUTOFOCUS Method
In order to use this method, you must first turn it ON. We described how to turn it ON earlier in
this section. After you turn it ON, please follow the step by step instructions below.
To Use AUTOFOCUS:
•
The AUTOFOCUS sensor sends out an invisible beam across the table between the 1 inch
and the 3 inch mark in the Y axis ruler for the M-300 Platform and the 2 and 4 inch mark for
the V-400, X-600 and X2-600 Platform laser systems. You will notice that it is indented
slightly.
•
Place your object between these two points vertically and anywhere on the table horizontally.
Refer to the diagram below.

•
Make sure that the laser system is in the main menu screen or the “File Display” menu.
AUTOFOCUS will not work in the other menus.
•
Press the “Z” button once on the control panel of the laser system. You will observe the Z-
axis Table (Engraving Table) move down and then up again, adjusting the table to the proper
focusing height. If the “Current Lens” choice in the menu system is not the same as the lens
you have installed, correct it by placing the cursor on the second line of the display, and
pressing the “Select” button to toggle you through your choices. Once the desired lens is
displayed, escape out of the menu and AUTOFOCUS again. This will bring the table up to
the correct height. The display will now show that the “Z Position” is “0.00” for that Focus
Lens.
•
If you desire to adjust the “Z Position” so that you are slightly out of focus, without exiting out
of the menu, simply bring the cursor over to the “0.00” part of the display and adjust the table
to the desired offset. The display will now show you how much you are out of focus. If you
were to escape out of the display and perform the AUTOFOCUS procedure again, the “Z
Position” will again show “0.00” to remind you that you are precisely in focus.
•
If you have purchased additional lenses besides the 2.0 inch lens upon original delivery of the
laser system, those other lens heights have been set at the factory. If you purchase
additional lenses after you have received your machine and need to set the ‘Focal Height” of
that lens, or you need to adjust your AUTOFOCUS, please follow the next procedure.
