I have had the same kinda problem when trying to run a pattern. FoKoP, are you having problems with that pattern that produces a rectangle of LOTS of little dots? That pattern doesnt work at all for me, it requires too much blanking for the laser to fully power up lol

Well I got my module today!

I went to hook it up to my scanner's TTL, and switched it on. I was hit with.... a TEM20 and around 20mw dot!

I thought the laser module was dead, and tht i'd have to get a refund. But I became suspicious of the TTL signal, and wires the laser PSU (5V) directly to the TTL input. And out comes a big bright green beam!

dave from LSP said that the signal from the program board must not be powerful enough to drive it.

BUT, for the time I had the laser hooked up, I saw that it DID do that multiple dot pattern properly, and I could see all of the dots, during daytime. despite the serious mode hopping and 20mw LOL

I am building a TTL "amp" and will post the results soon
