"Laser step complete" and "laser scan complete" are working again.

Problems:
1) Connections were wrong in the Software. 
2) Sometimes the connection to "laser scan complete" was lost (Wackelkontakt).
3) The VI was initialized with the wrong LabJack Channels.

Now:
1) fixed connections in the software.
2) switch to an other "channel" of the LabJack device for "laser scan complete".
3) The channels in the Cobra VI are for...
laser scan complete -> Channel 5
laser step complete -> 6

We definetely should keep an eye and check frequently the signals, that we do not have a lost connection (Wackelkontakt) again of these 2 channels.
