Command
timed_mark_abs
Function Moves the laser focus for the specified marking duration along a 2D vector from the
current position to the specified position (absolute coordinate values) within a 2D Image
Field.
Call timed_mark_abs( X, Y, T )
Parameters X Like mark_abs.
Y Like mark_abs.
T Duration of the complete mark vector. In µs.
As a 64-bit IEEE floating point value.
Allowed value range: [0…167,772,160]. The parameter is rounded to an
integer-multiple of 10. Out-of-range values are clipped.
If T < 5, then timed_mark_abs behaves like mark_abs.
Comments • Unlike mark_abs, the timed_mark_abs command does not execute the marking
process with the specified (by set_mark_speed or set_mark_speed_ctrl) mark speed.
Instead, the speed (that is, the number of Microsteps) is adjusted so that the vector
lasts as long as specified (see Chapter 8.9 ”Timed Commands”, page 274). The total
marking time is (for T  5) the sum of the specified (rounded) time and the set delays.
