A70 Support – Setup, Usage & Troubleshooting
Support resources for the high-power A70 PRO and A70 MAX blue-diode laser systems.
¶ About the A70
The A70 series is AtomStack's high-power open-frame line, built around a 70W blue diode laser. It comes in two sizes: the A70 PRO with a 500 × 400 mm working area (its frame accepts objects up to 600 × 645 mm) and the A70 MAX with an 850 × 800 mm working area. Motion runs on dual-axis linear guides on all three axes, at up to 400 mm/s (24,000 mm/min).
The A70 is aimed at cutting. It cuts 26 mm dark acrylic, 12 mm MDF, 25 mm pine wood and 0.05 mm stainless steel sheet. It also engraves anodized aluminum, brass, stainless steel and some iron-based metals. A double-pump air assist (about 60 L/min) is included, focusing is manual or automatic in about 8 seconds, and flame detection stops the job and raises an alarm if it sees fire. The machine also resumes engraving after a power cut. A control screen lets you run jobs without a computer, and the A70 also works with AtomStack Studio, the AtomStack app (Wi-Fi or hotspot) and LightBurn. Rotary attachments R1-B (V2), R2-B (V2), R6, R8 and R8 Pro are supported.
The A70 uses its own 36V laser module and connector, so it is not interchangeable with other AtomStack or third-party lasers. There is no protective enclosure for the A70 MAX, so plan for eye protection and smoke extraction.
Who it suits: small workshops and makers who cut thick wood and dark acrylic or work on large pieces.
