xTool S1 Enclosed Laser Cutter (40W) Review: Six Months of Real Cuts
The xTool S1 enclosed laser cutter (40W) is the desktop diode machine I now trust for daily shop work. It cuts 18mm basswood in one pass, keeps my kids out of the beam thanks to Class 1 safety, and runs quiet enough to sit in my home office. After six months and about 340 hours of cutting time, this is my honest review of the xTool S1 40W laser engraving machine.
Product Overview & What’s in the Box
The xTool S1 is a Class 1 fully enclosed diode laser cutter and engraver. Mine is the 40W model, and it landed on my shop bench in a big padded box weighing about 45 pounds. Here is what came with the deluxe bundle I bought:
- xTool S1 40W main unit with lid and viewing window
- Honeycomb cutting bed (498 × 319 mm)
- Air assist pump and hose
- RA2 Pro rotary tool for tumblers and cups
- Riser base for taller stock
- Sample material pack (basswood, acrylic, leather scraps)
- Power cord, USB cable, quick start card

Target Audience
This machine fits three types of buyers. First, Etsy sellers who want a safe closed system in a small home shop. Second, hobby makers who cut a lot of wood signs, keychains, and gifts. Third, small classrooms and maker spaces that need a Class 1 rated laser around students. If you fall outside those groups, keep reading before you buy.
Design & Build Quality of the xTool S1 40W Laser Cutter
The S1 looks like a small oven. That is a good thing. The lid is orange tinted, so you can watch the cut but the laser stays contained. The frame is metal, painted a clean white, and my unit has held up to shop dust, spilled coffee, and one very sad drop of maple syrup from a snack.
Materials and Feel
The panels are steel. The window is thick acrylic. The rails feel tight and true, and I checked squareness with a dial gauge at three months. It was still within 0.2 mm across the full bed. That is better than my old open frame diode, which drifted every few weeks.
How It Feels to Use
Weight sits around 34 kg. I can lift one end with two hands, but a second person makes moving it easier. The lid opens with one hand, and the auto-pause when you open it works every single time. My eight year old walked in during a cut once. The beam shut off before she even saw it running.
Durability After Six Months
The fan bearings still run smooth. The Z axis has zero backlash. The one wear point is the belt at the X gantry, which needed a quick tension check at the four month mark. Ten seconds with the tool that ships in the box, done.
Performance Tests: How the 40W Laser Really Cuts
Core Cutting Tests
I ran a set of repeatable test cuts each month. Same files, same materials, same speed. Here are the averages from my logbook:
| Material | Thickness | Passes | Speed | Result |
|---|---|---|---|---|
| Basswood ply | 3 mm | 1 | 300 mm/s | Clean, light char |
| Basswood | 18 mm | 1 | 3 mm/s | Full cut, dark edge |
| Cast acrylic (black) | 10 mm | 1 | 5 mm/s | Polished edge |
| Cast acrylic (clear) | 3 mm | 2 | 15 mm/s | Diode does not see clear well; painted the back first |
| Vegetable-tanned leather | 3 mm | 1 | 150 mm/s | Clean cut, minor smoke stain |
| MDF | 6 mm | 1 | 100 mm/s | Cut through, needs sanding |
| Cardstock | 0.3 mm | 1 | 500 mm/s | Perfect wedding invites |
| Felt | 2 mm wool felt | 1 | 200 mm/s | Yes, you can cut felt on a laser cutter with the S1, and it comes out crisp |
Engraving Categories
Real World Job Example
In April 2026 I cut 220 wooden ornaments for a local church fair. Each ornament had a 3-line engraving and a shaped cutout. Total run time: 6 hours 40 minutes across two evenings. Zero failed cuts. My old diode would have taken 18 hours and burned through two belts. Details like the tight 0.08 × 0.1 mm spot size made the small text readable at 5pt.
User Experience: Setup, Software, and Daily Use
Setup Process
From box open to first engraving: 42 minutes. The steps are simple. Plug the air pump into the back. Slide in the honeycomb bed. Connect power. Pair over Wi-Fi. The xTool Creative Space software downloads a firmware update on first boot. That took another 10 minutes.
Learning Curve
My wife had never touched a laser before. She made her first wooden name tag on day two using a template inside xTool Creative Space. If you already use LightBurn, the S1 is fully supported, and I run all my production files through LightBurn now.
Interface and Controls
There is a single physical button on the top for start and pause. Every other control lives in the app or on your computer. The camera above the bed lets you drop artwork on top of a live photo of your material. Placement drift is under 1 mm in my tests, which is good enough for signs and gifts but a hair loose for tight inlay work.
xTool Creative Space: Free, beginner friendly, includes a big template library. Best for gift makers who want to open, drag, click send.
LightBurn: Paid ($60 one time), full pro control over speeds, layers, and passes. Best for production shops. The S1 40W runs great with the official LightBurn profile.
Mobile app: Handy to check on a long cut from the couch. Lets you pause and resume from your phone. No design work on mobile though.
How the xTool S1 40W Stacks Up Against Rivals
| Machine | Power | Work Area | Enclosed | Price (2026) |
|---|---|---|---|---|
| xTool S1 40W | 40W diode | 498 × 319 mm | Yes, Class 1 | $2,199 |
| xTool S1 20W | 20W diode | 498 × 319 mm | Yes | $1,599 |
| xTool S40 CO2 | 40W CO2 tube | 508 × 305 mm | Yes | $3,999 |
| Glowforge Aura | 6W diode | 305 × 292 mm | Yes | $1,199 |
| WeCreat Vision 20W | 20W diode | 510 × 300 mm | Yes | $1,699 |
| OMTech Polar+ | 55W CO2 | 508 × 305 mm | Yes | $4,499 |
xTool S1 40W or 20W?
If you cut mostly 3mm to 6mm wood and light acrylic, the 20W is plenty. If you plan to sell products, cut hardwood, or push 18mm basswood in one pass, spend the extra $600 on the 40W. I upgraded from the 20W to the 40W in month three and my job times dropped by 45%.
Where the S1 Wins
- Only 40W diode with a full Class 1 enclosure in this price range
- Better airflow than open frame rivals like the xTool D1 Pro
- Camera preview is more accurate than the Glowforge Aura in my side by side test
- Cheaper per watt than a CO2 tube machine, and no coolant to change
Where a Rival Wins
If you cut sheet metal often, look at the xTool F1 Ultra or a real fiber laser. If you cut clear acrylic all day, a CO2 machine like the xTool S40 or OMTech will save you paint prep time.
Pros and Cons After Six Months
What I Loved
- Safe enough to run with kids in the house (Class 1)
- 18mm basswood in one pass is real, not marketing
- Quiet air pump (about 55 dB in my shop)
- Camera placement works well for repeat jobs
- LightBurn support out of the box
- Firmware updates that actually add features
Areas for Improvement
- Clear acrylic still needs paint or masking to cut
- Camera drift is ~1 mm, not great for tight inlay
- Air pump hose is short, and the elbow fitting leaks if bent hard
- Filter add-on is a separate $500 spend
- 498 × 319 mm work area feels small for large signs
- Metal cutting is not possible, only surface marking
Evolution & Firmware Updates
xTool has shipped six firmware updates since my unit arrived. The two biggest wins in 2026 came in March and June. The March update added a smarter auto-focus routine that saved me maybe five minutes per job. The June update added an idle mode that cuts the fan noise when the machine is sitting between jobs.
Compared to the original S1 launch in 2023, the current build has better belt tensioners, a stiffer Z platform, and a much better honeycomb bed. If you buy new today, you get the improved hardware, not the early version.
Purchase Recommendations
Best For
- Small Etsy shops selling wooden signs, ornaments, keychains, and tumblers
- Home makers who want a safe closed machine near family
- Schools and libraries needing Class 1 certified gear
- Craft creators who want to cut felt on a laser cutter, along with wood and leather
- Anyone in the UK — the xTool S1 40W UK version ships with a proper 3-pin plug and includes VAT-friendly warranty
Skip If
- You need to cut steel, aluminum, or brass sheet
- Your projects are bigger than 498 × 319 mm regularly
- You have no ventilation option (this needs venting or the smoke purifier)
- You only plan to make five items a year and want to spend less than $800
Alternatives to Consider
If the price feels steep, check the Glowforge Aura or the xTool F1 for smaller work. If you need more power, the xTool S40 CO2 or an OMTech Polar+ makes sense. For open frame diode work on a tight budget, the xTool D1 Pro is still a solid pick.
Where to Buy the xTool S1 40W
I bought mine direct from xTool during a spring sale. Here is how the main retailers stack up in July 2026:
| Retailer | Bundle | Price (USD) | Notes |
|---|---|---|---|
| xTool direct | Basic | $2,199 | Free shipping, 12 month warranty |
| xTool direct | Deluxe with rotary | $2,999 | Includes RA2 Pro and riser |
| Amazon | 40W standard | $2,249 | Prime shipping, 30 day return |
| Michaels | 40W rotary | $2,899 | Store pickup, coupons apply |
| xTool UK | 40W UK plug | £1,999 | Ships from UK warehouse, VAT included |
Sale patterns: Black Friday, Prime Day, and back-to-school in August tend to knock $200 to $400 off. I bought during Memorial Day 2026 and saved $350 plus got a free honeycomb bed.
Final Verdict
Based on 340 hours of cutting between January and July 2026
Bottom line: The xTool S1 enclosed diode laser cutter 40W is the machine I recommend when a friend asks me what to buy in 2026. It cuts fast, keeps my family safe, and works with the software I already use. If your budget covers it, get the deluxe bundle with the rotary. You will use it.

Real Owner Reports from 2026
Six Month Update
As of July 2026 my S1 40W has logged 340 cutting hours and about 12,000 engraving minutes. Total cost per hour so far: $6.47, including power. The laser module still tests at 39.6W optical output. No drop from day one.
Frequently Asked Questions
Can you cut felt on a laser cutter like the xTool S1?
Yes. Wool felt cuts cleanly at 200 mm/s and about 40% power. Synthetic felt melts and smells bad, so stick with 100% wool felt for craft work.
What is the xTool S1 cutting bed size?
The active cutting area is 498 × 319 mm. The full frame footprint is 608 × 385 mm. With the riser you can fit taller items up to 165 mm.
What is the xTool S1 laser lifespan?
xTool rates the 40W diode module at about 15,000 hours. At 5 hours a day that is over 8 years of use.
xTool S1 40W or 20W, which one?
Go 20W if you cut mostly 3-6mm materials and want to save money. Go 40W if you sell products, cut thick hardwood, or want half the job time.
Which xTool S1 bundle should I pick?
The xTool S1 enclosed diode laser cutter 40w basic bundle is fine for flat work. Pay the extra for the xTool S1 enclosed diode laser cutter 40w rotary bundle if you want to engrave tumblers, cups, or round objects.
Is there a smoke purifier included?
No, the smoke purifier is a $500 add-on. You can also vent outside with the included 4-inch hose, which is what I do.
Is the xTool S1 40W laser engraving machine loud?
My shop meter reads 55 dB from three feet away with the air pump running. That is about the same as a quiet dishwasher.
