The short answer: the xTool S1 40W is worth it if you want one enclosed machine that handles wood, leather, slate and opaque acrylic without compromise, and you want LightBurn. It is not worth it if you need clear acrylic or bare metal — no diode does those, at any wattage.
xTool S1 40W
Class 1 enclosed · 40 W optical diode · 498 × 319 mm · LightBurn and xTool Studio · infrared module available separately.
Check price on AmazonWhat it is
A fully enclosed diode laser with a lid interlock, sold in 20 W and 40 W versions. The 40 W is the one worth discussing, because 40 W is where single-pass cutting of 6 mm basswood becomes realistic, and single-pass cutting is what keeps a cut edge pale instead of charred.
Who it is for
People who have either outgrown an open-frame machine or skipped that stage deliberately. The enclosure means it can live in a spare room rather than a garage, and it means nobody in the house needs safety glasses while it runs.
What it does well
- Power that changes workflow. The difference between three passes and one is not just time — each pass re-burns the kerf walls, so a one-pass cut looks visibly cleaner.
- Bed size. 498 mm takes blanks that most enclosed machines force you to cut down first.
- Software freedom. LightBurn support means your skills and your project files survive the machine.
- An upgrade path. An infrared module adds metal marking without a second machine, and a rotary adds tumblers.
What owners complain about
Collected from listing reviews and forum reports rather than from hands-on use, because this machine has not been run for this site:
- Size. It is a large object. Measure the shelf before ordering, including lid clearance.
- Fan noise. The exhaust is audible. In a shared space this matters more than people expect.
- Shipping damage. As with every gantry machine, a proportion arrive with alignment knocked out. Unpack and test within the return window.
- Accessory cost. The rotary, riser and filter are separate purchases and they add up.
What it cannot do
Is the xTool S1 worth it?
If you are choosing a machine to keep, yes. The combination of enclosure, 40 W, a large bed and LightBurn is rare, and each of those is the thing people cite when they explain why they replaced their first laser. If your work is small and craft-scale, a cheaper enclosed machine will do the same job for less.

Is the xTool S1 worth the money?
For a buyer who wants one enclosed machine for several years, yes — 40 W, a 498 mm bed and LightBurn support are the three things people upgrade for. For small craft work, a cheaper enclosed diode is enough.
Can the xTool S1 engrave metal?
Coated, painted and anodised metal, yes. Bare stainless and aluminium need the separate infrared module, and even then it marks rather than deeply engraves.
What problems do xTool S1 owners report?
Mostly size and exhaust noise, some shipping-damage reports, and the running cost of accessories bought separately.
Does the xTool S1 need ventilation?
Yes. The enclosure contains smoke; it does not remove it. Duct it outside or run a filter unit.
