Longer Ray5 vs Atomstack A10 Pro: Which One Should You Buy?

Longer Ray5 vs Atomstack A10 Pro: power and cutting

Each listing states 10W optical output, so neither side wins on headline power. The Longer example pairs its 10W output with dual-beam technology and 0.06 x 0.06mm precision, while the Atomstack example pairs its 10W output with dual-compression spot technology and a 0.06 x 0.08mm spot. Rated speed matches: the Longer example lists 24,000 mm/min, and the Atomstack example lists 400mm/s (24,000mm/min).

Cutting claims differ in the materials named. The Longer example states cutting of 20mm wood boards and 30mm acrylic sheets. The Atomstack example states cutting of 10mm basswood and dark acrylic. Those are different materials and thicknesses, so read them as separate listing claims, not a head-to-head result.

Work area

The Longer example lists a 400 x 400mm work area, stated in its title as 15.75 x 15.76 in, with an extension kit expanding the area to 850mm x 400mm, stated as 33.46 x 15.75 in. The Atomstack example lists a 410 x 380mm engraving area. Neither bed is larger on both dimensions: the Atomstack example is longer on one side and shorter on the other, while the Longer example can grow with the extension kit, available for purchase separately.

Materials

Each title names wood, acrylic and metal. The Longer title names those three for DIY engraving, with cutting claims for wood boards and acrylic sheets. The Atomstack title adds glass, and its bullets describe clean, high-contrast marks on metal, wood and glass. Glass is the separator: the Atomstack example names it, and the Longer example leaves it Not stated.

Software and control

Control is where the listings differ sharply. The Longer example transfers data over Wi-Fi, USB cable, APP and TF card, supports offline operation, and adds a 3.5-inch touch screen run from a 32-bit core motherboard. The Atomstack example connects over Type-C or USB and supports LightBurn and LaserGRBL alongside its own app, for PC, Mac or Smartphone. The Longer listing names no LightBurn or LaserGRBL support, so weigh the stated options rather than assuming either side runs every program.

Safety and enclosure

Neither listing states a laser class, so neither side earns a class-based safety claim here. The Longer example states a protective cover and glasses, plus a built-in abnormal-shaking program that stops the machine when shaking is detected. The Atomstack example states a detachable magnetic protective cover that filters 97% of UV rays, plus included safety glasses. No OD or wavelength range is stated for either set of glasses, so they read as included accessories rather than rated protection.

Ventilation

Cutting wood and acrylic makes smoke, so plan ventilation before cutting. Vent outdoors or add a fume extractor, and stay with the machine while it runs. Keep a fire extinguisher nearby, and never laser PVC or vinyl. See our fume extractor guide for extractor options.

Support and warranty

The Atomstack example states a 365-day warranty from receipt of the product, with 24/7 service. The Longer example states ongoing technical support and 24-hour customer service, but no warranty term. That gap is the support difference: a stated term on the Atomstack side, support without a stated term on the Longer side.

FAQ: lasers and CNC

Which side has the larger work area?

Neither side is larger on both dimensions. The Longer example lists 400 x 400mm, expandable to 850mm x 400mm with an extension kit, while the Atomstack example lists 410 x 380mm. Compare the shape to the pieces you plan to make.

Do both machines run at 10W?

Each listing states 10W optical output. The Atomstack listing also states 60W machine power, which is input rather than optical output, so do not read it as laser power. The Longer listing states no machine input figure.

Which software runs each machine?

The Atomstack example supports LightBurn and LaserGRBL alongside its own app, over Type-C or USB. The Longer example transfers data over Wi-Fi, USB cable, APP and TF card with offline operation, and names no LightBurn or LaserGRBL support.

Can either machine cut metal?

Each title names metal among its materials. The Atomstack bullets describe marks on metal, wood and glass, and neither listing states a metal cutting thickness. Treat metal work as engraving and marking, not a stated cutting depth.

What warranty does each machine carry?

The Atomstack example carries a 365-day warranty from receipt of the product. The Longer example states ongoing technical support and 24-hour customer service, but no warranty term.
