I am ordering a RayFine 30w fiber laser. The only accessory im getting with it is the rotary. My main business is powdercoating and laser engraving tumblers (100w C02 Boss). I am looking to get my FFL and start engraving guns. I am thinking I need the fume extractor. It seems better than running a hose to a air pump. What is everybody else doing with their air? Thanks!
