There are a few ways to speed up the trace.
If you look at the [Tab] system value settings, you will see:
3 max optimized lit vector in ordinates ...
4 max optimized blank vector in ordinates .
5 maximum dwell in microseconds ...........
6 lit dwell overhang in samples ...........
7 what to do with dots ....................
8 dwell on dot in vertices ................
All of these settings apply to the way LaserBoy renders non-time-oriented color vector art to time-sampled-wave.
Values 3 and 4 take real (floating point) numbers for input. This is how far the laser dot can move, in any direction (2D or 3D) within the whole set of coordinate space (-32767 to +32767), in one sample. The default value is 600.0. That means that in one sample of a wave (1/48000 sec) the galvos will not exceed 600 coordinate locations of displacement. That's 600 out of 65565, or less than 1% of the total projection angle.
You will notice that there is a separate setting for lit and blank.
Setting these values to higher numbers will allow the galvos to move farther each sample (faster).
Value 5 is the maximum time in miliseconds to dwell on a spot before taking off in exactly the opposite direction. I made a big assumption here. I assumed that the greatest change in direction would take the longest time to overcome the inertia. So, this value is how long to sit on the spot for a 180 degree change in direction. All other angles are less than this and will get proportionally less dwell. The point is, that dwell samples eat up time. So, the fewer there are, the faster the image will scan.
The next setting, "6 lit dwell overhang in samples", is kind of like a compensation for hot spots that might appear in the art due to dwell. There is another related setting in menu 'x' called "7 black dwell" (yes or no). The idea is to prevent too much light piling up on the dwell point. But to prevent visible gaps in the line, you can make sure that "6 lit dwell overhang in samples" is some small positive integer amount and each dwell spot is guaranteed to be lit for this many samples before the galvo starts to move again.
The last two settings,
7 what to do with dots ....................
8 dwell on dot in vertices ................
have to do with "dots". A dot is a single point of light; not a line segment. Many beam shows have lots of dots in them.
You have three options for setting number 7:
1 ignore dots
2 remove dots
3 enhance dots by a dwell of [number]
Option 1 does nothing special with dots. If they are in the art, you will probably see them OK.
Option 2 identifies dots and eliminates them from the art. This is useful for cleaning up imports from DXF files. Option "6 remove equal vectors" is also good for cleaning up DXF imports.
Option 3 identifies dots and guarantees that each dot will be shown for a number of samples as determined by the setting "8 dwell on dot in samples".
(changed from vertices)
Since you have no dots, you might as well set this to ignore dots.
Does that make any sence?
