RASTER PROPERTIES (CONTROL PANEL)
RASTER POWER %
This field and slider allow you to set the firing current as a percentage of the maximum as set in the
configuration file. Laser tubes have a minimum activation current; setting this value too low (below
10%) could result in the laser not firing as this is under the minimum activation current. Keep in
mind that when setting the power below 10%, the tube may no longer fire as it has reached the
minimum activation current.
RASTER SPEED %
Set the engraving speed as a percentage of the maximum. Maximum speed is set in the config.xml
file. The raster routine in v4 is optimized so it only rasters nonwhitespace and minimizes the
acceleration distance. If you set the speed % very low such as 1% then the laser head does not
need much acceleration distance. Total time to engrave = (acceleration time + raster time). Since
acceleration time is also lower the total time is not linearly related to the speed %. However, the
energy/heat applied to the material is linear according to the speed %. For deeper engraving use
a slower speed.
BLACK/WHITE THRESHOLD
Adjust this slider to fade in or fade out portions of any image that is not black/white. Your computer
graphics card must be fast enough to use the slider in realtime to see the updates. This has no
effect on 1bit bitmaps or black and white images. If you have a computer with a slow graphics
card, set the threshold using the text box and enter the values manually.
IGNORE ALL VECTOR
Checking this box will only import raster data and ignore vector data. When processing a print job,
RetinaEngrave attempts to sort all the vectors for the fastest cut times. A drawing containing
millions of points or vectors will take up a large amount of memory and CPU which can cause a
