Commands - Scanlab RTC6 PCIe Board Installation And Operation Manual

3D Commands
These are, for example, the following
RTC6 commands:
• [*]3d[*]
• goto_xyz
• set_offset_xyz and set_offset_xyz_list
Except for the additional motion in the third
dimension, the 3D commands function identically to
their corresponding 2D commands:
• Specified vectors and arcs are split-up into
Microsteps, see Chapter 7.1.2 "Microstepping",
page 140
• The jump speed and mark speed are specified by
set_jump_speed and set_mark_speed, see
Chapter 7.1.1 "Marking with Vector Commands
and "Arc" Commands", page
Vector Commands, the speeds are automatically
determined from the specified jump or marking
duration
• 3D Image Field correction is applied in
accordance with the 3D correction table assigned
by select_cor_table or select_cor_table_list, see
Chapter 7.3.5 "Image Field Correction and
Correction Tables", page 173
• For Jump Commands and
the Laser Control Signals
while taking delay settings into account, see
Chapter 7.2 "Delay Settings – Coordinating
Scan Head Control and Laser Control", page 145
For the value range of the data, see
"Compatibility Modes", page

In RTC4 Compatibility Mode
RTC5 Compatibility Mode, the three coordinate
values are always scaled up to 20-bit values internally,
so that the three spatial directions are treated equally
with regard to the jump speed or mark speed.
The 3 coordinate values are internally always scaled
up to 20-bit values, so that the three spatial
directions are treated equally with regard to the
jump speed or mark speed.
With big z jumps, observe the different dynamics of
varioSCAN and 2D scan systems.

*_ReadMe.txt file supplied with the
3D correction file as well as from the user manual
of the 3-axis scan system/varioSCAN ("Technical
Specifications" chapter).
• If a z axis is to be used to hold the laser focus only
in a certain plane (especially in 3D systems
without a lens), then even 2D vector commands
can be used. 2D vector commands leave the
z position previously set with a 3D vector
command unchanged and only adjust the focus
length.
