Features:

1. Larger working area: 850*400mm maximum working area without the extension bar, meets 99% of laser engraving/cutting scenes.

2. More stable structure: Different from extending the Y-axis, Atomstack A20 Max uses the X-axis extension solution with better structural stability, which makes the A20 Max work stably in a larger working area and engrave/cut lines smoothly without jittering.

3. Tank chain bundling: The Atomstack A20Max adopts a tank chain wire bundling scheme that is not available in other models. The wire harness runs smoothly without entanglement, improving the wire life.
4. Super high power: works with 20W laser module. The latest four 6W laser coupling technology can cut 12-15mm paulownia, 8mm black acrylic, and even 0.05mm stainless steel sheet at one time. With autofocus design, Atomstack A20 Max can auto-focus in 10s.

5. The newly upgraded self-developed 32-bit motherboard: built-in 256-bit color scale, which makes the engraving work more accurate and has a higher contrast ratio. Your engraving work could be colorful!

6. Equipped with F30 Pro air assist kit as standard: the cutting capacity is greatly enhanced, and at the same time, the cutting accuracy and cutting quality can also be greatly optimized.
7. New non-clogging laser module: the new A20 laser module has a built-in tool-free focus module and a built-in air assist system. There is also a patented double-layer poly air hood design, which can ensure long time use without blocking the head and contaminating the lens, greatly improving the life of the laser.
8. Atomstack self-developed APP: Atomstack self-developed APP has been launched in Android application markets and the Apple APP store (you can also scan the QR code of the manual to download). It is small in size and multi-functional, bringing a new control experience. Come and have a try.
9. New eye protection design: The filter glass protects your eyes very well, filtering 97% of ultraviolet light, you can watch laser engraving/cutting without wearing goggles. Reduce your goggle expense and the inconvenience of wearing goggles.

10. Easy to install: The all-aluminum anodized structural design makes the machine stronger and more durable, and at the same time improves the accuracy of engraving. The installation can be completed in generally 20-30 minutes.

11. High compatibility: the machine is compatible with various softwares, such as LaserGRBL, LightBurn, supports Win XP / Win 7 / Win 8 / XP / Win 10, and also supports Mac system (LightBurn), file format supports NC, BMP, JPG, PNG, DXF, etc.
12. 20W upgrade compressed spot technology. Laser spot size 0.08mm*0.1mm. Engraving speed up to 300mm/s(18000mm/min).
13. One-piece rod: the machine uses a one-piece rod instead of a combined coupling. The stepper motor and screw rod are integrated, which makes the laser movement more accurate and the coupling more durable.

14. Laser temperature up to 2400℃.

15. Safety protection: configured with an emergency stop button. if there is an unexpected situation, stop the machine running at any time, and equipped with a reset switch and limit switch.
