Im new to the laser world, I have just got my 40w laser engraver, but when I connect everything
and plug my lap nothing happens!When I remove the back, I see the laser go to a metal ring on
the end of the tube instead of going thru.. any advice?
Any help will be apprecited.
I didn't find the right solution from the Internet.
