ok, now I see...
I think the problem is coming from the fact that firstly dmx is not really a good way to control lasers. Secondly, cuety is a simple dmx controller with a limited number of parameters.
So at the end the parameters you need to control the laser are not available in cuety. In your case i think the first issue is the 1 channel of the dmx chart that you cannot access from cuety.
I cannot create custom fixture files but you can use the VBuilder software to create your own fixture file that would allow you to use this laser with cuety, Putting the 1 chanel to a custom fader may be a first solution, knowing that as cuety can only manage 2 custom parameters you will need to have only 2 "customs" in vbuilder or the first one will be over written.
I hope this will help you,
