When in Raster mode, it is advisable to use a PPI
setting of 500 or higher. If using less, the image
resolution of the engraving is reduced. In some rare
cases, using less than 500 PPI may produce better
results. In Vector mode, any setting up to 1000 PPI
may be used. Keep in mind that using less than 150
PPI may result in the pulses being spread so far apart
that they may or may not touch one another and give
an effect such as perforated paper. Higher PPI settings
cause more of a melting or burning effect on the edges.
Low PPI settings may reduce burning, melting, or
charring, but may result in a serrated or perforated-
looking edge. Increasing or decreasing the PPI setting
has absolutely no effect on engraving speed.
Save
A unique feature of the Printer Driver is being able to store the your settings in a file. By clicking
Save, the “Save Engraving Setup” dialog box will appear which allows you to enter in a file
name to save the settings that you have appearing on the Printer Driver screen. These settings
will be stored in this file that has a “.LAS” extension. DO NOT rename the extension because
the driver will not recognize the file as a laser settings file if it does not have the “.LAS”
extension. These files can be stored in any directory on your hard drive or floppy disks and you
can have as many setting files as your disk(s) can hold.
Load
To recall settings that you have previously saved, click on the “Load” button and choose the file
with the settings that you would like load. The settings that you have currently on screen will be
replaced by the settings from the “.LAS” file.
Focus
Before engraving or cutting your application material, you must first load it into the machine and
adjust the Z-axis table until the material is at the correct distance away from the Focus Lens.
You do not need to use this button unless to would like the Focus Carriage to position itself
somewhere else in the field besides it’s (1”,1”) default Focus Position. If you would like a
different Focus Position Than the default, click on this button, a pop-up screen will appear and
your mouse pointer turns into a crosshair. The large white area represents the laser systems
entire engraving area. Move the crosshair to the position on screen where you would like the
focus carriage to move to in the engraving area of the laser system.
Once you are at that (X,Y) position, simply click your mouse button and that (X,Y) coordinate
automatically transmits to the laser system as the new Focus Position. Now press the “STOP”
+ “DOWN” buttons at the same time and observe the Focus Carriage move exactly to the (X,Y)
position you clicked on.
