Quick verdict
The A24 Pro is AtomStack's budget open-frame diode built on a one-piece aluminum frame that arrives assembled. Its 24W module combines four 6W diodes, and AtomStack claims 600 mm/s and a 0.06 x 0.06 mm spot. In CraftEtch's hands-on test it cut 13 mm pine in one pass and 10 mm acrylic in two, and engraved glass and leather well. The $459 machine-only price is low, but it does not include an air pump, focusing is by a fixed block, and the bed is only 365 x 305 mm. Flame and tilt detection, a key lock, Wi-Fi and app control are standard. AtomStack's page, manual and store data disagree on bed size and weight, so treat the spec sheet with care.
What you still need
An air pump kit (the manual lists single and dual pump kits as add-ons; AtomStack's F30 set was out of stock and its F80 set costs $99, so confirm which fits before ordering), a honeycomb or matrix panel, fume extraction or an enclosure, the R6 roller ($149) or R8 chuck ($199) for tumblers, the optional touch screen if you want offline jobs without a phone or computer, extra glasses for anyone else in the room, and a LightBurn licence if you want itMaterial reality check
Cuts wood, plywood, MDF, balsa, paulownia, leather, card, paper and dark opaque acrylic; AtomStack's one-pass figures are 13 mm pine, 15 mm basswood plywood and 10 mm black acrylic. Engraves wood, bamboo, leather, rubber, slate, glass, anodized aluminum and coated metals, and can mark tumblers with a marking coating. It has no infrared source, so it cannot mark bare metal properly or cut any metal, and like every diode it cannot cut clear or blue acrylic. Never cut PVC or vinyl, even though one AtomStack image shows 'vinyl for lasers': chlorine-based vinyl fumes are toxic and corrode the machine.Better alternative if
if you want much more cutting power with the air pump and autofocus included, the A40 Pro V2 costs about $310 more: AtomStack A40 Pro V2Scores

Pros and cons
Why we like it
- Unibody frame arrives assembled; a hands-on tester had it running in about 15 minutes
- 24W from four 6W diodes cut 13 mm pine in one pass in CraftEtch's test
- 600 mm/s top speed is quick for an open-frame diode in this price range
- Small 0.06 x 0.06 mm spot (maker figure) gave fine detail on photos, glass and leather in testing
- Wi-Fi and app control plus LightBurn and LaserGRBL support, with flame and tilt detection and a key lock
Watch out for
- No air pump in the Machine Only box, only the air hose, so clean cuts need a pump bought separately
- Fixed focus with a focus block, no autofocus and no camera
- Small 365 x 305 mm bed, and AtomStack's own page lists it as 360 x 280 mm
- All bundles were out of stock on 9 October 2026; only the bare machine was available
- A 2023 design whose specs disagree across AtomStack's own page, manual and store data (bed size, weight, precision)

How we rank: by our own scores for power, speed, ease of use, safety and value, from the maker's published specs and independent tests where they exist. Some links earn us a commission (for example TwoTrees, SainSmart, Gweike and Amazon). That never changes a score or the order of a list (disclosure).
