By [Laser Engravers Guide Editorial Team](https://laserengraversguide.com/about/) · Updated October 30, 2026 · [How we score](https://laserengraversguide.com/how-we-research/)

Our score comes from manufacturer specs, professional reviews, and owner reports. It is not a hands-on lab test.

## The verdict
The S1 40W is the enclosed diode to buy when cutting matters: Class 1 safety, a 50 cm-wide bed, autofocus and 40 W that slices thick plywood and dark acrylic, with LightBurn support for pros. It lacks a camera, air assist is extra, and at about $1,800 it's within reach of the xTool P2S, which cuts faster and handles clear acrylic. Buy the S1 if you need Class 1 in a shared space; buy the P2S if you can vent a CO2 and want the widest material range.

### What we like

- 40 W diode inside a Class 1 enclosure; xTool claims 18 mm wood in a single pass
- Biggest bed of the enclosed diodes here (498 × 319 mm), plus conveyor passthrough up to 3 m
- Multi-point autofocus and curved-surface engraving; five flame sensors, emergency stop and lid-open stop
- LightBurn support alongside xTool's own software

### Watch out for

- No camera: positioning uses xTool's laser-head 'Pin-point Positioning' instead
- Air assist is an add-on, and you still need to vent outside or buy a purifier
- Blue diode: no clear acrylic, and thick cuts are slow next to a 55 W CO2
- Amazon's only S1 listing is a $1,819 'Rotary Bundle', and xTool's Canadian store lists the S1 under clearance

- xTool's cutting claim is '18mm cherry wood in a single pass'; it doesn't publish a separate basswood/plywood maximum on the listing.
- xTool lists stainless steel as diode-engravable (a dark oxide mark); the optional 2 W IR module handles bare metal and plastics properly.
- The Amazon listing (B0CQ84BDTX) is titled 'Rotary Bundle'. Confirm the RA2 Pro rotary is in the box before treating it as included; we list rotary as optional.
- xTool's Canadian store listed the S1 as 'Clearance' in Oct 2026 while newer M2/F2 lines take the spotlight, so stock may thin out. The 20 W S1 no longer appears on xTool's US product page.
- Per xTool's FAQ, LightBurn handles focusing, framing and the RA2 Pro but not curved-surface mode or material measurement.
Specs are compiled from manufacturer listings and independent reviews and may change between production runs. Laser makers re-bundle often, so confirm what's in the box on the Amazon page before buying.
The xTool S1 40W is a 40 W blue diode laser inside a Class 1 enclosure, with the biggest bed of any enclosed diode we track: 498 × 319 mm. It’s the machine we point to when someone wants serious cutting power in a home, office or classroom without moving to a CO2 laser. The only Amazon listing, a “Rotary Bundle”, sells for about $1,819 (check today’s price and what’s in the box). It’s our pick for the best enclosed diode for cutting wood and a top choice for home safety. If you’re unsure whether you need a cutter or an engraver, the [laser matcher](https://laserengraversguide.com/tools/laser-matcher/) can help you decide.

## Who the S1 is for (and who should skip it)

It’s for small shops and serious hobbyists who cut a lot of plywood, hardwood and dark acrylic in a shared space: a spare room, a home office, a classroom. Class 1 means nobody in the room needs goggles while the lid is shut, and that matters more than any spec if you live with other people.

Skip it if clear acrylic or glass engraving is on your list. No blue diode cuts clear acrylic, and the [xTool P2S](https://laserengraversguide.com/laser-engravers/xtool-p2s/) CO2 does it for about $1,100 more, if you can vent a Class 4 machine. Skip it if you want camera placement: the S1 has none and uses xTool’s laser-head “Pin-point Positioning” instead. And if you mostly engrave and cut thinner stock, the Class 1 [Creality Falcon A1 Pro](https://laserengraversguide.com/laser-engravers/creality-falcon-a1-pro-20w/) adds a camera and costs about $700 less.

## Cutting power and practical use

xTool claims the 40 W head cuts 18 mm cherry wood in a single pass. That’s a maker claim, not a measurement, and xTool doesn’t publish a separate plywood maximum. Treat it as the ceiling, not the everyday setting. Cuts that thick will still be slower than on a 55 W CO2, but they put the S1 well ahead of 10–20 W enclosed diodes. Our [best laser cutter for wood](https://laserengraversguide.com/posts/best-laser-cutter-for-wood/) guide puts it in context.

The rest of the feature set suits production work. Multi-point autofocus measures the surface and supports curved-surface engraving, so a warped board or a domed lid comes out evenly. An automatic conveyor feeder (with an extra rail) passes stock up to 3 m long through the machine. Five flame sensors, an emergency stop and a lid-open stop round out the safety package. LightBurn support is a real plus for pros who already have a workflow.

Metal is the weak spot. xTool lists stainless steel as engravable, but a blue diode leaves a slow, dark oxide mark with low contrast. For bare metal and plastics, add xTool’s optional 2 W IR module, or see our [best laser engraver for metal](https://laserengraversguide.com/posts/best-laser-engraver-for-metal/) guide for fiber options.

## What you’ll need beyond the box

- **Ventilation.** Class 1 contains the light, not the smoke. The S1’s exhaust fan has to go somewhere: duct it out a window with [4-inch foil ducting](https://www.amazon.com/dp/B01EUURUVM?tag=laserengraversguide.com-20), add an [inline duct fan](https://www.amazon.com/dp/B07JB292JC?tag=laserengraversguide.com-20) for long runs, or use the [xTool SafetyPro AP2 purifier](https://www.amazon.com/dp/B0DHCJQS1J?tag=laserengraversguide.com-20), which xTool pairs with its high-power machines, if you can’t vent outside. Our [ventilation guide](https://laserengraversguide.com/posts/laser-engraver-ventilation-guide/) covers sizing.

- **Air assist.** It’s an optional add-on on the S1. If you plan to cut thick stock, budget for it; air assist keeps cuts cleaner and reduces flare-ups.

- **A riser for rotary work.** Standard clearance is 42 mm. The [S1 Riser Base](https://www.amazon.com/dp/B0CPKYY7GQ?tag=laserengraversguide.com-20) raises it to 125 mm while keeping the machine Class 1 (xTool also sells a Class 4 riser, so check which one you’re buying). The [RA2 Pro rotary](https://www.amazon.com/dp/B0CJ2BXQ7N?tag=laserengraversguide.com-20) handles tumblers, glasses and rings; check whether your bundle already includes it.

- **Eye protection for the exceptions.** A pair of [445–455 nm glasses](https://www.amazon.com/dp/B08R4PMCHR?tag=laserengraversguide.com-20) for maintenance and alignment. If you add the IR module, remember that blue-diode glasses don’t block 1064 nm.

- **Fire basics.** An [ABC extinguisher](https://www.amazon.com/dp/B084P5PPNC?tag=laserengraversguide.com-20) beside the machine. Even with flame sensors, don’t leave cutting jobs unattended.

More options are on the [accessories page](https://laserengraversguide.com/accessories/).

## Reliability and warranty

The S1 comes with xTool’s 1-year warranty, and xTool’s store offers paid extensions up to 24 months. The bigger question is the S1’s place in xTool’s lineup. xTool’s Canadian store listed it as “Clearance” in October 2026, and the 20 W version no longer appears on xTool’s US product page, so stock may thin out. That doesn’t make it a bad buy, since accessories and LightBurn support are mature, but confirm the bundle contents and seller on Amazon and don’t pay a premium for a machine on its way out.

## Bottom line

The S1 40W is the enclosed diode to buy when cutting matters: Class 1 safety, a 50 cm-wide bed, autofocus with curved-surface support, LightBurn compatibility, and 40 W that handles thick plywood and dark acrylic. It lacks a camera, air assist is extra, and at about $1,800 it sits close to the P2S, which cuts faster and handles clear acrylic. Buy the S1 if you need Class 1 in a shared space. Buy the P2S if you can vent a CO2 outdoors. Our [xTool S1 vs xTool P2S](https://laserengraversguide.com/posts/xtool-s1-vs-xtool-p2s/) comparison walks through that choice, and the larger [xTool P3](https://laserengraversguide.com/laser-engravers/xtool-p3/) is the Class 1 CO2 option if your budget stretches much further.

## xTool S1 40W FAQ

### Does the xTool S1 40W come with a rotary?
Maybe. The only S1 listing on Amazon is titled 'Rotary Bundle', which suggests the RA2 Pro rotary is included, but confirm the box contents on the listing before you rely on it. We treat the rotary as optional. Rotary work also needs a riser base on the S1.

### Can the xTool S1 cut clear acrylic?
No. It's a blue diode, and blue light passes straight through clear acrylic. The S1 cuts dark, opaque acrylic. For clear acrylic you need a CO2 laser such as the xTool P2S.

### Do I need safety glasses with the S1?
Not in normal use. The S1 is a Class 1 laser, and xTool says its cover lets through only 0.35% of the light. Keep a pair of 445–455 nm glasses for maintenance or any time a lid or interlock is open, and note that xTool sells both a Class 1 and a Class 4 riser base. Only the Class 1 version keeps the rating.

### Does the S1 work with LightBurn?
Yes. Per xTool's FAQ, LightBurn handles focusing, framing and the RA2 Pro rotary, but not the S1's curved-surface mode or material measurement, which stay in xTool's own software.
