Review on ATOMSTACK A5 20W Laser Engraving Cutting Machine: Upgraded Precision, Eye-Protection Design, DIY Laser Marking on Wood, Leather, Vinyl by Kristen Simpson

1 star because customer support and documentation is TERRIBLE. They are mostly on their own and use/rely on the user forums for help on the product or on GRBL/Lightburn. This is a very good basic entry-level "beginner" laser, but it does have some issues. At least start with the goods. For the price, this is a great laser for beginners. He can do some really good cuts and burns. Now for the bad. Customer service comes first. Abroad they offer the only email support and I have sent three emails but still have not received a response to my questions. Very disappointing, because after three days of use (Mac OS with Lightburn) the laser does not connect. Get "laser may be paused or busy" and I didn't get any help from the support department which basically means I have a useless laser. When it works, it works very well with wood. The product is simple and easy to set up, engraves and cuts wood very well. But I have to disagree that this laser is capable of engraving acrylic. This is a light laser diode and the light/laser just goes through the acrylic and burns whatever is underneath the acrylic. Acrylic will NOT be engraved. I tried contacting the support department to see what settings they recommend but again got no response. So I'll give it another week and if I don't get an answer I'll return this product. Update: The tolerances of this laser are very bad.
