Answer: The A70 series features a specialized design and is currently not compatible with laser modules from other AtomStack models or third-party brands.
Note:
- The A70 series uses a 36V power supply and a dual-connector port, which differs from standard configurations.

Answer: The A70 series features a specialized design and is not compatible with engraving machines from other brands.
Note:
- It operates on a 36V power supply and uses a dual-connector port, which differs from standard configurations (see Figure 5 above).
Answer: The A70 series can engrave on anodized aluminum, brass, stainless steel, and certain iron-based metals. It can also cut thin stainless steel sheets up to 0.05 mm.
Note:
- Blue diode lasers (used in the A70 series) are optimized for non-metallic materials. For metal engraving, infrared laser R30 V2, MR20 fiber laser, or lasers with 1064 nm wavelength are more effective. The MR20, for example, can engrave precious metals like silver and gold (ventilation is required to avoid inhaling metal dust). Currently, the A70 series does not support installation of R30 V2 or MR20 infrared laser modules.
Answer: The A70 series supports Wi-Fi connection or direct hotspot connection to the mobile app. However, when attempting to use LightBurn software for remote control via IP address, some compatibility issues may arise. While the machine can connect to a mobile phone via Wi-Fi or hotspot, LightBurn may not operate stably over the IP connection, which can interrupt engraving tasks.
Note:
- To connect your phone, search for "AtomStack" in your app store or download it from the AtomStack official website. The default hotspot connection password is: 12345678
Answer: Yes, the A70 series can engrave on regularly-shaped curved surfaces (such as cups and thermos bottles) using a rotary attachment.
Note:
- Recommended rotary attachments include R1-B (V2), R2-B (V2), R6, R8, and R8 PRO. Refer to the rotary setup video for proper connection and usage.
Answer: Yes, it can. For recommended settings, please refer to the 70W engraving parameter chart, available via the USB flash drive included with the product, the AtomStack official website, or by contacting customer support.
Note:
- When cutting leather, use higher speeds for high-power settings, and slower speeds for low-power settings. Improper settings may cause burnt edges or even ignition. The recommended approach is to use multiple fast passes instead of a single slow one.
Answer: Yes, it supports rotary accessories such as R1-B (V2), R2-B (V2), R6, R8, and R8 PRO. Simply connect the rotary attachment to the Y-axis motor port of the engraving machine to use it.
Note:
- All AtomStack machines use white-head sequential wiring cables for rotary device connection. Please note that R1 V2, R2 V2, and other V2-series rotary tools produced before July 12, 2024, may not include the white-head sequential cable. If needed, please contact customer support for a solution.
Answer: The A70 series is the world's first 70W blue diode laser engraving machine, offering a 30–50% increase in cutting performance compared to similar-power devices. It supports high-speed engraving at up to 24,000 mm/min and achieves precise focusing in just 8 seconds, allowing users to begin work quickly.
Product Highlights:
Answer: A70 MAX has no suitable protective enclosure.
Answer: Yes, two F8 honeycomb panels can be joined together to form a large panel suitable for A70 MAX, and A70 PRO can use F4 honeycomb panels.
Note:
- Two F8 panels can be joined together and are suitable for MAX models.
Answer: Yes, the engraving machine comes with a double pump air assist. The airflow is about 60L/min and the noise is <60dB.
