Ok, now I have that kinda figured out.
My next question, what's a better way to connect the galvos to the easylase?. Single ended or symetrical?, Which is easier? I was re-reading
this thread, where Astroguy was trying to hook up the dt-40 to the easylase. I think he ended up doing it single ended, but can it be don symmetrically?, would it be easier and safer?. Do I really need the 4k7 resistors?, I was left with the impression that those were not really needed, but I don't mind soldering them (I'm sure I can find some SMD resistors around, I have a lot of junklying around

).
And, one last question, for the moment. I was reading the easylase manual, and some pics on the thread I mentioned before. What are pins 3 and 16 for? It says intensity, but for what?, each laser has its own TTL signal on pins 5-7 and 18-20.
I guess that's it for the moment
Sorry to be such a pain
