List Command
set_wobbel_offset
Function
defines a wobbel shape shift in the direction of motion or perpendicular to the direction
of motion.
Call
set_wobbel_offset(OffsetTrans, OffsetLong)
Parameter
OffsetTrans
,
OffsetLong
Transversal and longitudinal offset as signed 32-bit values.
Allowed range: ±32767. Larger values will be clipped.

Comments
• Offsets can be defined for “classic” wobbel shapes (circle, ellipse, sine, figure-8) as well
as for “freely definable wobbel shapes” (see
chapter 8.4 "Wobbel Mode", page 167
).
• The summed up wobbel amplitude including offsets may never exceed ±(2
17
–1).
• At the beginning of the wobbel marking offsets are set as hard jumps. This applies also
in case of switching-off or non-using the wobbel mode, for example, when using a
jump command (analogously to “classical” wobbel shapes longitudinal amplitudes).

Short List
Command
set_wobbel_vector
Function
defines a (linear) section of a wobbel shape.
Call
set_wobbel_vector( dTrans, dLong, Period, dPower )
Parameter
dTrans
,
dLong
Microstep of a linear wobbel shape section
in bits
in 64-bit IEEE floating point
format. Allowed value range [–256.0 … +255.0].
dTrans
is the microvector component perpendicular to the direction of
motion (which is either the laser trajectory or the direction of motion defined
via
).
dLong
is the microvector component in the direction of motion.
Period
Unsigned 32-bit value. Allowed range: [0 … 65535].
= 1 … 65535: number of microsteps
= 0: the wobbel shape will be switched off
dPower
Microstep of the relative laser power in 64-bit IEEE floating point format.
Allowed range [–1.0 … +1.0].
Unallowed values will be clipped to the corresponding limits.
