Optimizing the Delays
The following figures show the various effects of
non-optimized delays on the letters “RTC“.
LaserOn Delay too short
At the beginning of a mark vector
the laser is switched on, even
though the mirrors have not yet
reached the necessary angular
velocity.
Burn-in effects at the start points
of the respective vectors result.
LaserOn Delay too long
The laser is turned on too late at
the beginning of a mark vector.
The first part of the vector is not
marked.
LaserOff Delay too long
The laser is turned off too late
after the last mark command of a
line or polyline. The laser is still
on, even though the mirrors have
already stopped or move only
very slowly.
The results are burn-in effects at
the end points of the respective
vectors.
LaserOff Delay too short
The laser is turned off after the
last mark command of a line or
polyline, although the mirrors
have not yet reached the end
position of the vectors.
The respective vectors are not
marked completely.
