Delayed Short set_wobbel
List Command
Comments • For identical amplitudes (Longitudinal = Transversal), the wobbel startpoint is
(cont'd) permanently referenced to the coordinate system, that is, independent of the current
direction of motion. By set_wobbel_direction, a fixed reference direction can be set
which differs from it.
• For an angle, ellipse-shaped wobbel movements can result in more or less small jumps
after reaching the corner, depending on the current wobbel phase. This does not occur
(= "rounded corners") if the wobbel motion is exactly circular
(Longitudinal = Transversal).
• Longitudinal = 0 produces a sine-shaped wobbel motion across the direction of
movement.
• When defining the wobbel shape and its frequency take the dynamics of the scan head
and laser into account. Otherwise, an overheating and even a permanent damage of
the system may occur, see
Choosing Appropriate Parameter Values", page
• The present wobbel amplitude can be recorded by
set_trigger/set_trigger4/set_trigger8
((transversal << 16) + longitudinal).
RTC4RTC6 Basically unchanged functionality.
More wobbel shape: elliptical, direction dependent adjustable, see also
set_wobbel_mode.
In RTC4 Compatibility
Transversal by 16. The allowed value ranges decrease accordingly.
RTC5RTC6 Unchanged functionality.
