I have a 60W Omtech laser and I’m trying to cut a basic shape out of 3mm plywood (ordered from Amazon Prime). I am on about cut #125,328 (honestly, I’ve lost count but I’ve tried to cut the shape over 20 times now), and it’s still not all the way through.
I know my focus is fine.
I just cleaned my mirrors.
But it’s still not cutting. Is my laser tube going bad? How do you know?
Settings are now a 5mm/sec and 100% power with air assist on, and I’m not through 3mm, and it’s sure trying, but it’s still not through, after 20+ passes.
