I watched several video and it was an easy decision to purchase the 700x700x500 enclosure for my 400x40 engraver.
This works well with my Ortur Laser masrer 2. Very happy with it and I would recommend it to anyone I know looking for laser enclosure.
great product, love the enclosure, glad I went with the larger one.
