Laser Engraver Forum

Hey everyone I have what I believe is an eBay or amazon special laser engraver I bought it second hand and I really know nothing about them I had it working awhile back but put it in storage because of a move I took it out to play around with but the laser is not burning anything
The laser is on but not half as bright as it should be like it’s in rest mode ? Anyone have any ideas what’s going on ? Like I said I’m really new to all this and will try to answer questions the best I can
