1. With set_auto_laser_control with Ctrl = 7 and with equidistant geometric pulse spacing specified at
spot_distance/spot_distance_ctrl.
2. No “Automatic Laser Control“ is active (spot spacing may vary).

For set_auto_laser_control with Ctrl = 7 the marking result shows largely equidistant spots as long as the acceleration
does not change too much within a 10 µs cycle.
”Spot Distance Control”
With Automatic Laser Control
set_auto_laser_control with Ctrl = 7
& spot_distance
Equidistant laser pulses = “usable“ portion
