Set
This button must be pressed after adjusting the Power, Speed, and PPI settings in
order for these changes to take effect. If forgetting to click on “Set”, and clicking on the
“OK” button instead, the settings will go back to the previous ones and will engrave the
object with the incorrect settings.
Advanced
Turning this switch ON will permit the changing of the PPI settings. If the switch is
turned
OFF, the word “Auto” will appear in the PPI column and will be colored gray.
Since 500 PPI is the setting that is used most often, “Auto” sets the PPI to 500
automatically and does not allow change unless the “Advanced” switch is turned back
ON.
Resolution
This setting is the image resolution of the engraving in DPI or dots per inch. There are
six DPI settings to choose from: 1000, 500, 333, 250, 200 and DRAFT. The
resolution can also be referred to as horizontal lines per inch or fill spacing. This is how
many raster strokes per vertical inch of travel that the motion system steps down to
produce an engraving. Higher resolutions will produce cleaner and deeper engraving
but take longer to engrave. Lower resolutions produce a coarser and shallower image
but are quicker to engrave. Experiment with the different settings and note the results.
Corel Bitmaps
This switch is for CorelDraw! users
ONLY . Turn this switch ON only when there is an
imported monochrome or grayscale bitmap in CorelDraw!. If printing any drawing that
has a bitmap in it and forgetting to turn this switch ON, everything else except the
bitmap will print. If the bitmap does not engrave, go back and turn the switch ON,
select the bitmap only, and print Selected Objects Only in the software. Make sure to
leave this switch OFF if there is no bitmap present. This switch should remain
OFF if
using software other than CorelDraw!.
B/W Raster
This switch simulates laser printer output and is very useful if using a drawing with many
colors, shades of gray, or many outlines. It is recommended to turn this switch ON
when using ClipArt because there may be some underlying cutting lines hiding behind
some filled areas. Having this switch ON gives a what-you-see-is-what-you-get output
very similar to laser printer output. The entire drawing will be engraved, including all
outlines, and only one power level will be used which is black. The color change ability
of the driver is essentially turned off and all colors are engraved as
