Posting a bit late, but last weekend @cory and I cleaned and aligned the laser.
Mirrors 1 and 2 looked pretty clean, mirror 3 and the lense were in need of cleaning.
As for alignment, mirrors 2 and 3 were needing a minor realignment.
All in all everything lookes pretty good. did some test cuts and 1/8 ply cut very well at 25 speed 35 power, 1/4 ply cut well at 20 speed and 40 power.
