SECTION 5: THE LASER DASHBOARD
Frequency
The frequency setting is only active on vector processes, and controls the number of laser pulses that
the laser fires per inch of travel. The frequency is set in the dashboard and can be adjusted from 1 to
100%. A lower frequency number will have the effect of less heat because fewer pulses are being used to
cut the material. Lower frequency rates are helpful for products like wood, where charring is evident at
higher frequencies. High frequencies are useful on materials like acrylic where a large amount of heat is
desirable to melt or flame polish the edges.
Dithering
Dithering is used only for Raster engraving and has no effect on vector cut lines. This setting defines how
the dot patterns will be engraved in raster images that contain grayscale images, blends, or color. The
Dashboard offers six different dithering patterns to enhance your engraving projects. The default mode
is Standard. This mode can be used for all images including photographs, but some images improve
when engraved with other dithering patterns. For more information, go to "Image Dithering" on page
87.
Offset
Offset allows you to focus at any point above or below the surface of your material. When engraving
acrylic, many users like to focus above the surface to produce a "softer" finish to the engraving.
Conversely, when cutting acrylic, many users like to focus about half way into the acrylic. Offset allows
you to do this automatically. A positive value will move the table away from the focus lens. A negative
value, such as -.095, will move the table closer the focus lens.
