Ctrl Command pause_list
Function pauses execution of the list and disables the “laser active” laser control signals.
Call
pause_list()
Comments • pause_list is synonymous with the previous command stop_list , which is often
confused with stop_execution . Therefore, it is preferable to use pause_list .
• If pause_list is called during execution of a list, the command causes the “laser active”
laser control signals to be disabled (then the laser output ports are in the high imped-
ance tristate mode) and keeps the scan system in the most recently defined state – even
if in the middle of microvectoring. The PAUSED status (queryable via
get_status ) is set,
but the BUSY status is left unchanged. Continuation via execute_list_pos or
release_wait or via an external start will be suppressed. However, stop_execution or
an external list stop is possible. restart_list , stop_execution or an external list stop will
end suppression of the list start.
• If processing of a list should be continued, then the command restart_list must be
used. After the successful restart_list command, the scan system resumes the planned
movements (of the current command) and the “laser active” laser control signals are
reenabled (the laser is started with the standard laser parameters, i.e. without any soft-
start or similar parameters that might have been defined prior to
pause_list ). The
PAUSED status is then reset (here too, BUSY remains unchanged).
• If, during calling of the
pause_list
command, no list is currently executing (BUSY status
not set) or a list has already been halted via
pause_list
or
set_wait
(PAUSED status set),
then the
pause_list
command will be ignored (
get_last_error
return code
RTC5_BUSY
;
the laser is then already off).

Ctrl Command quit_loop
Function stops the repeating automatic list change started with start_loop .
Call
quit_loop()
Comments • Before list execution is stopped, the current list will fully execute until the next
set_end_of_list command is encountered.
• If no start_loop command was previously issued, then quit_loop will have no effect.
