Longer vs ATOMSTACK Spec Breakdown
Laser Power Output
The ATOMSTACK A40 Pro V2 offers a maximum 48W output, which it achieves by switching modes via a physical button. This allows you to toggle between 24W and 48W depending on whether you need fine engraving or heavy cutting. The Longer Ray5 provides a fixed 40W laser module. While 40W is powerful for most desktop tasks, the ATOMSTACK’s higher peak wattage gives it an advantage for demanding single-pass cuts on thicker materials. If you frequently switch between delicate detail work and aggressive cutting, the adjustable power on the ATOMSTACK provides more flexibility than the static output of the Longer machine.
Working Area Size
Workspace dimensions are critical for large projects. The Longer Ray5 features a generous 385 x 385 mm working area. This square format allows you to engrave large boards or cut multiple items side-by-side without repositioning. The ATOMSTACK A40 Pro V2 uses an A40 size frame. While the exact millimeter dimensions for the A40 platen are not explicitly listed in the provided data, it is generally smaller than the Ray5’s expansive bed. If you regularly work on wide panels or need maximum surface real estate, the Longer Ray5’s larger footprint is the superior choice for efficiency and capacity.
Engraving Speed
Speed impacts how quickly you can finish jobs. The Longer Ray5 boasts a maximum engraving speed of 24,000 mm/min. The ATOMSTACK A40 Pro V2 lists a speed of up to 500 mm/s. When you convert the ATOMSTACK speed to minutes, it equals 30,000 mm/min. This makes the ATOMSTACK significantly faster in terms of raw movement velocity. For high-volume production runs where time is money, the ATOMSTACK’s higher speed allows you to complete tasks more rapidly. The Longer Ray5 is fast, but the ATOMSTACK holds the edge in pure travel speed metrics.
Connectivity and Control
Control interfaces vary between these two machines. The Longer Ray5 includes a 3.5-inch touchscreen for real-time monitoring and parameter adjustments. It supports USB, TF card, Wi-Fi, and app connectivity, offering versatile options for both online and offline operation. The ATOMSTACK A40 Pro V2 features a one-key switch for power modes but does not list a built-in touchscreen or specific connectivity ports in the provided data. If you prefer tactile control and immediate feedback without a computer, the Longer Ray5’s touchscreen and multi-option connectivity provide a more user-friendly and flexible experience.
Cutting Capacity
Cutting thickness determines what materials you can process. The Longer Ray5 can single-pass cut 20 mm pine wood and 15 mm acrylic. With multiple passes, it handles up to 40 mm wood and 50 mm acrylic. The ATOMSTACK A40 Pro V2 cuts 18 mm wood and 9 mm acrylic in a single pass. The Longer Ray5 clearly outperforms the ATOMSTACK in maximum cutting depth, especially for wood and acrylic. If your work involves thick materials or you need to cut deeper sections efficiently, the Longer Ray5’s superior cutting capacity makes it the stronger tool for heavy-duty fabrication.
