20W Diode Laser Engraver

The ATOMSTACK A20 Pro is a desktop laser engraver and cutter delivering 20W optical power through four 6W coupled diodes. It provides a 400x400mm work area and includes an F30 Pro air assist kit, an R3 Pro rotary roller and an F2 honeycomb table. A 32-bit motherboard with 256-bit colour scale drives the motion system.

Makers cutting thick sheet or marking metal

Users who need single-pass cuts in 12mm tungsten board, 8mm black acrylic or 0.03mm stainless steel will benefit from the high optical power and 0.08x0.1mm focus spot. The package suits hobbyists and small workshops adding rotary and offline control. Buyers who require a larger bed or a CO2 tube for non-metal throughput should look at other classes of machine.

Open-frame kit needing ventilation and 130W supply

The engraver ships as a frame kit that must be assembled on a stable bench with fume extraction and the supplied 130W power unit. The F30 Pro air assist connects to the onboard controller for cleaner cuts, while the R3 Pro roller enables cylindrical objects. The honeycomb table protects the surface and allows debris fall-through during long jobs.

Questions about this item

Does the engraver need an external computer or can it run jobs from its own control panel?

The machine includes a terminal control panel that supports offline engraving so it can run without a connected computer once a job is loaded.

Will the F30 Pro air assist kit and F2 honeycomb table fit on my existing 400x400 mm frame if I already own one?

Both the F30 Pro air assist kit and the F2 laser honeycomb working table are supplied with this engraver and match its 400x400 mm working area.

How can I verify the 0.08×0.1 mm focus spot is performing correctly after setup?

Engrave a test pattern on mirror stainless steel or ceramic; the ultra-fine spot should produce detail comparable to a 300 W CO2 laser.
