I just finished installing and setting up my new 80W laser. Got all the mirrors aligned, and at all four corners, the laser is hitting the third mirror in the same spot, nearly exactly at the center.
When I set the laser to the focal length and do a pulse on a piece of wood, I get a center dot, but also a kind of half moon around it.
I attached tape directly to the laser cutter head and pulsed, and when I pulled off the tape, I had two holes instead of one. (will try to attach pictures to show).
Any idea what this problem could be? Faulty laser head? Bad focal lens? I'm pretty new to lasers and have not experience this problem before.
Any help would be greatly appreciated!
Thanks,
Tim
