I have a couple of problems. Bought a used ULS 25 w laser engraver.
Supposed to be working but........... I need a way to find out how much power I might have , and how to detect the beam through the 2 mirrors.
I made an adapter and mounted the final lens in front of the laser origin.
It will burn thru paper w/ a pinhole. I cant get any sign of a beam more than 2 inches away. Since its invisible I dont know how far it may be off center.
Not sure if the power I have is enough to be doing 25 watt work.
Any and all suggestions welcome. Thanks very much. LL.
