Scanlab RTC 4 Installation And Operation Manual page 25

(3) If a list change is necessary while a polyline is executed,
but not auto_change (page 75)
and the second list is started immediately after
complete execution of the first list, then the same as for
the mark delay is required for the polygon delay:
polygonD + LOnD > LOffD
Otherwise, it could occur that the laser is off for the rest
of the polyline.
SCANLAB recommends to use the
command for automatic list change or to add a small
software delay of the size (LOffD - LOnD - polygonD)
previously to starting the second list.
