AtomStack A20 Pro V2

20W Professional Diode Laser Engraver & Cutter

The AtomStack A20 Pro V2 is a versatile 20W diode laser engraver and cutter designed for makers, hobbyists, and small businesses who need reliable performance across a wide range of materials. Featuring an advanced independently-developed motherboard and unique dot compression technology that delivers an ultra-fine 0.08 × 0.10 mm laser spot, the A20 Pro V2 produces crisp, detailed engraving on wood, leather, anodized aluminum, coated metals, 304 mirror stainless steel, ceramics, dark glass, and more. Its 20W laser output cuts through 17 mm wood and 15 mm black acrylic in a single pass.

With a spacious 400 × 365 mm working area and engraving speeds up to 400 mm/s, the A20 Pro V2 handles everything from detailed artwork to production-scale batch jobs. The integrated linear guide rail system ensures smooth, precise motion while the aluminum alloy frame provides rock-solid stability. Built-in limit switches and a cross-line positioning light deliver 0.01 mm engraving accuracy for pinpoint alignment. For safety, it includes flame detection (with Z2 slider), a 15° tip-over alarm, and resume engraving after power loss. The A20 Pro V2 connects via USB and Wi-Fi 2.4G, and works seamlessly with LightBurn, LaserGRBL, AtomStack Studio, and the AtomStack mobile app.
