Ctrl Command goto_xyz
Function moves the output point (of the laser focus) along a 3D vector at jump speed 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 goto_xy. However,
microvectorization will be calculated like a 3D command and hence will influence the
effective jump speed in the XY plane.
Call
goto_xyz( X, Y, Z )
Parameters
X, Y, Z
absolute coordinates of the jump vector end point in bits as signed 32-bit
values; allowed range:
•for
X
and
Y
: [–524288 … 524287]
•for
Z
: [–32768 … 32767]
Out-of-range values will be edge-clipped.
Comments • Except for the additional motion in the third dimension, this command functions simi-
larly to the goto_xy command (see the comments there).
• The X and Y axes can be controlled with 20-bit resolution, the Z axis with 16-bit resolu-
tion. The RTC
®
5 (in RTC
®
5 mode as well as in RTC
®
4 compatibility mode) automatically
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.
•The
DirectMove3D
parameter of the set_delay_mode command determines the type
of Z-axis motion (linear or with stepwise correction).
• 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 page 126).

5 • Extended range of values
• The command returns only after the motion has completed (see comments for
goto_xy).
•RTC
®
4 compatibility mode: see goto_xy, the value range for Z coordinates is identical
for the RTC
®
5 and RTC
®
4.
Version info Last changes:
• with version DLL 520, OUT 519: behavior for coordinate transformations with
at_once
= 2 (see page 612)
• with version DLL 527, OUT 529: The command returns only after the motion has
completed.
