Tried to engrave a stainless tumbler and it let me know something is wrong. I dont use this laser very much. Had Raymond install it back in 2013.
Anyway the mirrors are shot. Would show you a pic but not allowed. I have 3 new ones on the way.
I also think the tube itself is weak. Can I post a link to youtube of it firing?
