Undelayed set_wobbel_vector
Short List
Command
• For laser power variation with Ctrl = 5 (half period), dPower needs to have the opposite
sign. Unlike with automatic laser control, the multiplication factor can't be inverted.
• By using an "empty" wobbel shape set_wobbel_vector(0.0, 0.0, 1, 0.0), you can
also multiplicatively vary the nominal laser power P0 without needing to explicitly
wobbel (for another alternative, see set_multi_mcbsp_in).
• When you switch off the wobbel shape (not by deactivation via set_wobbel_mode),
the nominal laser power P0 will be emitted at the port assigned via Ctrl if
set_wobbel_control
power P0 multiplied by the external factor from
• If the wobbel shape gets switched off while the wobbel mode remains active, then the
shape will automatically switch to Mode = 1 (horizontal figure-8).
• The wobbel mode with "freely definable wobbel shapes" also needs to be switched on
via set_wobbel_mode.
• Variable laser power for wobbel shapes can't be combined with variable laser power for
automatic or vector-based laser control (parameterized mark commands). Wobbel vari-
ation overwrites other variations if the respective Ctrl parameters are identical. Though
unidentical Ctrl parameters are allowed, they serve no practical purpose.
• When defining "freely definable wobbel shapes" make sure that the microvectors of
each individual wobbel vector does not exceed the maximum positioning speed signi-
ficantly. Otherwise, a galvanometer overheating may occur, see also
