Bought this laser cutter off Facebook Marketplace about 6 months ago, but I wound up not needing it.
It is attached to a piece of plywood, has the air pump, honeycomb, 10W laser, and a zippered cover with an exhaust port to keep the smoke contained. Other than that, I probably cant answer any other questions about it since im not the expert. My brother verified that it is working when we got it, but it has sat ever since.
Everything you need to get going is included, including the cables.
