I recentaly finished building my 100mw blu-ray running on a ddl driver set to 110ma. I was able to focus it and burn stuff. I am using an acrylic lens. But Today when I tried to light a match I tried to focus it and as the dot got smaller it turned into a rectangle. Once it was a rectangle I could not get the laser to focus to a smaller pinpoint size dot for burning. The dot now stays about 2 mm big and won't burn. :'(
How do I get it to focus right it was working fine the day before? :-/
