TL;DR
AtomStack A20 Pro 1064nm is a fiber marking variant for metal engraving without a separate galvo bench. Different machine class than diode A20 Pro V2: buy for metal marking, not wood cutting.
Best for
What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Fiber metal marking
A fiber source marks bare and stainless steel without spray : the right tool for tools, jewelry, and industrial tags. It will not cut wood or acrylic; pair it with a diode or CO₂ if your shop needs organics too.
LightBurn compatible
LightBurn support means advanced layers, camera tools, and workflows many makers outgrow the stock app with. Confirm your exact controller board before assuming full features : some machines need a paid license separately.
Galvo speed class
Galvo mirrors move the beam instead of a heavy gantry : engraving speeds that feel instant on small fields. Trade-off: tiny work area versus a flatbed diode; ideal for jewelry, tags, and batch marking, not large signs.
Our verdict
Ideal if you
AtomStack A20 Pro 1064nm Fiber 20W fits shops that mark stainless, aluminum, and tools daily without a CO₂ bay. A solid bench option for jewelry, tags, and small batches.
Skip if you
Skip if wood, leather, or cast acrylic pay your bills. Deep metal cutting and large industrial panels often need more fiber headroom or a different machine class.
Pros
- Fiber marks metal: does not cut wood or acrylic
- Software listed on the profile: test your workflow (LightBurn or maker app) on scrap first
Cons
- Does not cut wood, leather, or acrylic: metal marking workflows only
- Fume extraction still matters for coated metals and marking sprays

ComMarker · Fiber · $1,299 – $1,899
The ComMarker B4 is a popular entry-level fiber galvo engraver for jewelry, tools, and metal gifts. Marks stainless, aluminum, and brass without spray. Small marking field: not a cutter for wood or acrylic.
Atomstack · Hybrid · $1,299 – $1,899
AtomStack A24 Pro packs a diode engraver plus fiber marking into a smaller footprint than separate machines. Niche for jewelry-scale metal marking plus wood: not a full workshop fiber or high-power diode.
Gweike · Fiber · $1,499 – $2,199
Gweike G2 packages a 20W fiber galvo in a desktop form factor. Solid option if you want metal marking with Gweike ecosystem familiarity from their CO₂ lines.
