Normal para_mark_abs
List Command
Function moves the laser focus at marking speed along a 2D vector from the current position to the
specified position (absolute coordinate values) within a two-dimensional image field and,
simultaneously as well as linearly, changes the signal parameter selected via
set_vector_control
Call
para_mark_abs( X, Y, P )
Parameters
X, Y
P
Comments • If vector-defined laser control has not been previously activated via set_vector_control,
then para_mark_abs will behave like
P will then be ignored.
• If vector-defined laser control is activated, then simultaneously with the laser focus'
motion (Sky writing isn't taken into account here) the signal parameter selected via

• There is no abs mechanism for P. P will, if necessary, be clipped to the maximum allowed
value.
• If para_mark_abs is used along with position- and/or speed-dependent laser control
for the same control parameter, then the current value of P will be used as the basis of
the 100% value for laser control (see

absolute coordinates of the mark vector end point in bits as signed 32-bit
values; allowed range: [–8388608 ... 8388607] (out-of-range values will be
edge-clipped). The complete value range [–8388608 ... 8388607] is only
usable as a virtual image field e.g. for (enabled) Processing-on-the-fly
applications. The current coordinates will be clipped to [–524288 ... 524287]
