What reviewers say
X4 Laser Engraver
Reception is limited: just 4 ratings averaging 3.8 out of 5. That is too few to draw firm conclusions about reliability or support.
Pros
- Power for the price class
Cons
- Too few reviews to judge consistency
AtomStack Ace Pro V2 A20 Pro V2 Laser Engraver
Rated 4.3 out of 5 from 232 ratings, owners generally treat it as a solid budget 20W cutter with a big bed. Complaints cluster around assembly, focus setup and the limits of diode cutting.
Pros
- Cuts thin plywood and dark acrylic reliably for the price
- Large bed fits bigger signs and panels
- Detailed engraving thanks to the small spot size
- Safety alarms and resume feature are useful
Cons
Questions and answers
- Which is better for cutting 3/4-inch plywood?
- Neither diode laser cuts 3/4-inch plywood in one pass. The Mecpow X4's 22W gives it an edge on thicker stock and multi-pass cuts. The AtomStack A20 Pro V2 handles thinner plywood and basswood well.
- Is the AtomStack worth the extra money?
- Check the current prices on this page first. The AtomStack's flame sensor, tip-over alarm, and 232-rating history justify a premium for most buyers. The X4 only wins if you need the bigger bed or TF card printing.
- Which one is safer to run in a garage?
- The AtomStack. It has flame detection and a tip-over alarm that buzzes past a 15-degree tilt. The Mecpow X4 lists no such sensors, so you would need your own smoke and fire precautions.
- Do both work with LightBurn?
- Yes. Both list LightBurn and LaserGRBL support. The X4 adds Linux and TF card printing; the AtomStack adds Android and iOS apps.
- Which engraves metal?
- Both mark coated or anodized metal, not bare steel. The AtomStack names anodized aluminum and coated metals. The X4 claims metal generally, which usually means coated surfaces.
- Which has the larger work area?
- The Mecpow X4 at 410 x 400mm versus 400 x 365mm on the AtomStack. The difference is small, about 10mm by 35mm.
