Powerhouse for the price
Cuts 10 mm basswood in one pass like nothing. Auto air assist and autofocus make workflow faster than my old 10W machine.
Great cutting, OK engraving at 24W
The 24W mode does nice detail, but not as crisp as my dedicated 10W head. Still, the switchable module is super convenient.
Be prepared for safety setup
Built a full enclosure and added external ventilation. It’s a must for a Class 4 open frame. Once set up: terrific performance.
Controller hiccup after 3 months
Main board failed mid-job. Support eventually replaced it but communication took weeks. Works fine since the swap.
Air assist integration is a win
Being able to switch air on cutting layers only improved edge quality and reduced cleanup time on MDF.

The Atomstack ACE A40 Pro V2 offers class-leading power and advanced automation features for experienced users. It's a versatile workhorse for both cutting and engraving, but requires a strong commitment to user-implemented safety.
