I had to do some reasearch buying somewhat new to this, I found out that DMX is very very very limited in terms of what it can and can't do. Now the laser am buying is a 1W Blue laser with 9 channel DMX. My question is, is DMX that bad? Anyway to overcome just having to use what it has stored, I'd love to make my own images and texts but as I research, DMX won't really allow it. BTW : Am pretty new to the forum so if am posting at the wrong page then shout at me :)
