Vector Waveforms
Vector waveforms consist of a series of small steps that are updated at a frequency
high enough such that they create a waveform that appears continuous to the scanning
system. Vector waveforms should be structured so that the commanded acceleration
and velocity do not exceed the scan system saturation limits. Typical vector applications
include laser marking and 3D printing, where accurate tracking of complex waveforms is
required.
It is frequently difficult to choose an optimization waveform for applications such as
marking due to the complex, non-repetitive waveforms processed. In these cases a
typical optimization waveform is a constant velocity command broken by a series of stop
and start points over the full field. (See Figure 6.4) The velocity chosen should be the
maximum velocity expected in the application. If the vector waveform is repetitive, such
as a structured raster or step, the actual scan waveform should be used during the
tuning process.
