Hi, Sorry to ear that you get issues with your fixtures.
Are you using the last version of cuelux (1.5.4) if not you can download it here:https://www.visualproductions.nl/downloads/
Did you test the 2 dmx modes of the fixtures?
I've tested the fixture file here and from the monitor I can see the dmx channel changing like requested in the manual. So I have no idea from where the problem could come.
Could you check the dmx monitor in cuelux and see if the gobo channel is changing ( ch7 for 16 ch mode or ch9 for 18 ch mode)
