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.

A. Nguyen3/52025-04-11
Air assist integration is a win

Being able to switch air on cutting layers only improved edge quality and reduced cleanup time on MDF.

FAQ

What is the actual working area of the Atomstack ACE A40 Pro V2?
💡
Official specs list 385 × 400 mm. Some listings vary slightly, but 385 × 400 mm is the reliable figure.
Is the laser power really 48W?
💡
Yes. The module combines eight 6W diodes and offers a physical switch to toggle between 24W (engraving) and 48W (cutting) optical output.
Does it support LightBurn?
💡
Yes. It works with LightBurn and LaserGRBL. For best results, enable the automatic air assist via M7/M8 in your LightBurn layers.
Is an enclosure required?
💡
Highly recommended. This is a Class 4 open-frame diode laser. Use a full enclosure with proper fume extraction and wear OD6+ 455 nm safety glasses during setup/maintenance.
Can it cut thick wood or acrylic in one pass?
💡
With the 48W mode, it can single-pass through common woods up to ~18–20 mm and black acrylic up to ~7–10 mm under optimal settings. Material quality and air assist strongly affect results.
What materials can it engrave?
💡
Wood, leather, coated metals, painted/black anodized aluminum, ceramics, slate, cork, paper, cardboard, opaque acrylic, and more. Clear/white acrylic generally won’t absorb blue diode light.
Does it have autofocus?
💡
Yes. The V2 adds one-key autofocus using a probe plus a motorized Z. You can still fine-tune focus manually if needed.
Is air assist included and controllable by software?
💡
Yes. The ACE A40 Pro V2 ships with the F60 automatic air assist kit. You can toggle it in software (e.g., M7/M8 in LightBurn) to minimize charring and improve cut quality.
