Normal mark_abs_3d
List Command
Function moves the laser focus at marking speed along a 3D vector from the current position to the
specified position (absolute 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_abs. However,
microvectorization will be calculated like a 3D command and hence will influence the
effective marking speed in the XY plane.
Call
mark_abs_3d( X, Y, Z )
Parameters
X, Y, Z
Comments • Except for the additional motion in the third dimension, this command functions simi-
larly to the
• The X and Y axes can be controlled with 20-bit resolution, the Z axis with 16-bit resolu-
tion. The RTC
upscales Z coordinate values internally to 20-bit values, so that the three dimensions of
space can be handled equivalently in terms of the supplied jump speed value.
• During calculation of the Z output value to the scan system, any previously defined
offset to the Z coordinate and focal length is taken into account (see

as a virtual image field e.g. for (enabled) Processing-on-the-fly applica-
