A quick review for on on my time with the 8W laser. I’ve been using it on an MPCNC with a Rambo control board. So far its has worked really well, I’ve mainly used it for picture engraving. the dot burn size I’ve been achieving in MDF and pine has been <0.1 and images at 256 pixel resolution come out with really surprising quality. My main use for this laser was intended to be for cutting ply up to 5mm and acrylic. I've just finished the air assist for it and intend to start on some of the cutting projects soon. The laser has been very stable on jobs that have been at times a few hours in burn time. George has been very helpful in answering questions that have come up. I'd recommend this laser if you are considering it.
