Normal mark_rel_3d
List Command
Function moves the laser focus at marking speed along a 3D vector from the current position to the
specified position (relative coordinate values) within a three-dimensional process volume.
Restriction If the 3D option is not enabled or no 3D correction table has been assigned (see
select_cor_table), then the command will have the same effect as mark_rel. However,
microvectorization will be calculated like a 3D command and hence will influence the
effective marking speed in the XY plane.
Call
mark_rel_3d( dX, dY, dZ )
Parameters
dX,dY,dZ
Comments • The coordinates for the mark vector's end point are to be supplied as relative coordi-
nates with respect to the current position. Otherwise, the command is identical to
mark_abs_3d

relative coordinates of the mark vector end point in bits as signed 32-bit
values; allowed range:
• for X and Y: [–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 applica-
tions. The current coordinates will be clipped to [–524288 ... 524287] (real
image field size) during runtime directly prior to use of the correction table.
• for Z: [–32768 ... 32767] (out-of-range values will be edge-clipped).
