Hi Cnczone, I'm attempting to diagnose a drop in power on my 100W Thunder Laser Mars. The machine is around 1.5 years old.
Cleaned mirrors & lens, aligned mirrors, but still low power.
I noticed the burn mark when aligning the mirrors is creating a ring shape, which as far as I can recall, it wasn't doing before. Does this mean anything to anyone, I can't find any references to this issue in the forums.
Here's a photo
