Atomstack A40 Pro V2 vs xTool S1 40W
Technical comparison · Diode laser (405–460 nm)
Two 40 W diode lasers with the same wavelength: what differs is price, 850 € against 2250 €, and equipment. The xTool S1 has autofocus and a passthrough slot; the A40 Pro V2 has neither.

| Software notes | The system offers extended compatibility with the industry's leading standard software, ensuring operational flexibility across both Windows and macOS platforms. It fully supports LightBurn, the preferred choice for professional users seeking advanced management of layers, cutting parameters, and vectorization, as well as LaserGRBL, an open-source alternative ideal for simpler and more immediate engraving operations. Additionally, the machine is compatible with the manufacturer's proprietary mobile application, enabling remote control and file transmission via local Wi-Fi. This triple option allows users to adapt their workflow to specific project needs, supporting common vector and raster file formats such as NC, DXF, BMP, and JPG. | Device control is primarily managed through the proprietary xTool Creative Space software, an intuitive and constantly updated application ideal for managing graphic workflows and calibrating cutting and engraving parameters. For users requiring professional features or established workflows, the machine guarantees compatibility with LightBurn, the industry standard. The software integration allows for surface mapping and automatic positioning without the need for traditional cameras, simplifying file preparation in both Windows and macOS environments via USB or Wi-Fi connections. |

The differences that matter
- Price 850 € vs 2250 € → the A40 Pro V2 costs 1400 € less at the same rated power.
- Autofocus and passthrough only on the S1 → less setup per material and pieces longer than the bed.
- Bed 400×400 mm vs 498×319 mm → the A40 takes work up to 400 mm wide, the S1 reaches 498 mm in length.
- Speed 24000 vs 36000 mm/min (manufacturer's stated values) → large engravings finish sooner on the S1.
Which one to choose
Choose A40 Pro V2 if…
A40 Pro V2: a square 400×400 mm bed, 1400 € less, and LightBurn, LaserGRBL or a mobile app over Wi-Fi. It suits a workshop that engraves and cuts panels within 400 mm and sets focus by hand. The trade-off: no autofocus or passthrough, and a stated top speed of 24000 mm/min against 36000.
Choose S1 40W if…
xTool S1 40W: the bed is 498 mm long and the passthrough lets you run longer pieces by feeding the material through; autofocus saves re-measuring height with every material change. The trade-off: 1400 € more and a short side of 319 mm instead of 400 mm.
