DX 200mw DildaLazor Focusing issue! HELP

[akhen]

Hello, my dilda lazor just arrived, but i have some problem with damn lens.
When i focus, i can see small dot only up to 1-1.5meters, then i got a big dot. I can burn things very well, but over 1mt dot grow up and the screw its at his maximum tightness

No its in the correct way

when you unscrew it the dot should get smaller, right now it's focusing to a pinpoint and spreading back out

if you focus it properly the beam will only be straight and be more of a typical laser

Today i noticed that when i dont use the cap, screwing in only the lens i succeed to get a small beam, and a small dot for kilometers. The problem is in the cap i guess [smiley=sad.gif]. Maybe the screw thread is too short?

I think you should try turning it the other way, as your focusing it for short distances ( burning ) .

You're laser is fine. When you focus it to a small dot up close, it gets big at distances. When you focus it to infinity, it won't be a good burner but the dot will stay smaller. I can make you a paint diagram to show why this happens if you want.
