Is the xTool S1 Worth It? A Buyer’s Checklist for Budget-Conscious Small Shops

Look, if you're a small shop owner or a solo maker staring at the xTool S1, the price tag isn't nothing. It's an investment. And the last thing you want is to sink a couple grand into a machine only to find out it can't do what you actually need.

This isn't a review. It's a checklist—six things I've learned to evaluate before buying any desktop laser. I've been managing procurement for a small manufacturing shop for about 6 years now, and I've made almost every mistake in the book. This list is designed to help you avoid my $1,200 'lesson learned' with a different desktop laser last year.

I'm going to focus on the xTool S1 specifically, because that's what you're here for. Let's get into it.

What This Checklist Is For

This checklist is for you if you are a small business owner, a workshop manager, or a serious hobbyist considering the xTool S1 for manufacturing small parts, prototypes, or personalized goods. You're not looking for a toy. You're looking for a production tool.

We'll cover six key decision points. After each step, you'll have a clear 'Go' or 'No-Go' for that aspect.

1. Step 1: The 'Real' Material List (Not Just the Marketing)
2. Step 2: Metal Cutting: The Truth About the 20W & 40W Modules
3. Step 3: Cutting Thickness: Managing Expectations
4. Step 4: Software Setup: The Hidden Workflow Cost
5. Step 5: The Rotary Tool for Cylindrical Engraving
6. Step 6: Total Cost of Ownership (TCO) Check

Step 1: The 'Real' Material List (Not Just the Marketing)

Every laser engraver's spec sheet lists a dozen materials it 'can' process. Wood, acrylic, leather, glass, metal-coated items. The xTool S1 is no different. But the question isn't can it. The question is how well, and at what cost.

From my experience, the xTool S1 handles the standard stuff really well for a desktop unit. Engraving on coated metal (like anodized aluminum tumblers) is excellent. Cutting 3mm basswood plywood is clean and fast. Acrylic engraves beautifully.

Here's where the list gets tricky:

• Clear Acrylic: The S1's CO2 module cuts clear acrylic better than the diode module. The diode module struggles with transparent materials. This is a fundamental physics thing, not a defect. (Note to self: I almost assumed all laser modules handle clear acrylic the same way. They don't.)
• Thick Acrylic: Cutting 6mm+ clear acrylic requires multiple passes, which increases time and wear.
• Raw Metal: The xTool S1 cannot cut solid metal sheets like steel or aluminum. This is crucial to understand before you buy. For that, you're looking at a fiber laser or a CNC mill.

Checkpoint: Make a list of the top 3-5 materials you need to process daily. If 80% of your work is wood, acrylic, coated metals, or leather, the S1 is a strong fit. If you need to cut raw metal, stop here. The S1 is not for you.

Step 2: Metal Cutting: The Truth About the 20W & 40W Modules

Here's the part where marketing hype often clashes with reality. You'll see claims about 'cutting metal' with the diode modules. Let me break it down from a buyer's perspective.

The xTool S1 with the 20W or 40W diode module can mark or engrave metal. It does this by applying a marking solution (like CerMark or a specialized spray) to the metal surface. The laser then fuses the solution to the metal, leaving a dark, permanent mark. It's great for serial numbers, branding, and functional labels.

But cutting through a metal sheet? No. Not with the current diode modules. The power density isn't there.

I had a client once who was convinced the 40W module could cut thin aluminum (<0.5mm) for a small parts jig. They saw a video on YouTube. The creator had actually used a marking solution on the aluminum surface, then removed the coating. The end result looked like a cut, but it was just a deep engraving that compromised the material's integrity. That's a $450 learning experience.

Now, the xTool S1 does offer a fiber laser module, which can cut thin metals. That's a different product entirely. (I'm not a fiber laser expert, so I won't speak to the specific specs. The point is: if you want to cut metal, buy the fiber laser module, not the diode one.)

Checkpoint: Define 'cutting metal' precisely for your workflow. If you need to cut through raw steel or aluminum, the standard S1 with diode module is a No-Go. If you need to engrave or mark metal, it's a Go.

Step 3: Cutting Thickness: Managing Expectations

The xTool S1 is a desktop machine. Its power output (20W or 40W) dictates its cutting capacity. Expecting it to cut 18mm plywood in a single pass like an industrial 150W CO2 laser is a recipe for disappointment.

Based on my tracking of user forums and some internal tests we ran in Q2 2024, the practical cutting limits are:

• 20W Diode Module: Maximum 5-8mm basswood or poplar in a single pass. For acrylic, you're looking at 2-3mm max per pass.
• 40W Diode Module: Similar to 20W but faster. You can cut up to 10mm soft wood in a single pass. Acrylic: 3-4mm per pass. The speed difference is noticeable.
• CO2 Module: The S1's optional 40W CO2 module is better for acrylic and clear materials. It can cut up to 6-8mm acrylic in a single pass.

I'm not 100% sure on the exact CO2 specs because I've only used the diode modules extensively. Don't hold me to those numbers—check the official xTool specs. But the principle stands: for thick wood or acrylic, you'll need multiple passes.

One trick I learned the hard way: always test on scrap material before committing to a production run. The first time we tried to cut 6mm birch plywood, the laser barely made it through. We had to adjust focus and increase power by 15%. That test saved us from wasting a whole batch.

Checkpoint: What is the thickest material you need to cut? If it's 8mm or less of soft wood/acrylic, the S1 can handle it (with multiple passes if needed). If you need to cut 12mm hardwood, look elsewhere or be prepared for very slow, multi-pass work.

Step 4: Software Setup: The Hidden Workflow Cost

This is where many buyers get tripped up. The hardware is great, but the software can make or break your productivity. The xTool S1 uses LightBurn (a third-party, industry-standard software) and xTool Creative Space (their proprietary software).

LightBurn is the real deal. It's used by commercial shops everywhere. It supports layered designs, material libraries, and precise control. If you're serious, you pay the $60-$80 license fee. This is a cost of doing business, not an optional extra.

xTool Creative Space is fine for beginners or simple designs. But for production work, it's limited. I've tried using it for batch jobs, but the lack of proper nesting features and material saving options was a dealbreaker.

From a procurement perspective: factor the LightBurn license into your TCO. Also, factor in the time to learn it. I spent about 5 hours learning LightBurn's interface before I felt comfortable. That's a hidden onboarding cost.

I remember a conversation with a fellow shop owner who said, 'I thought I could just use the free software. A week later, I realized I needed a real tool.' That's a classic penny-wise, pound-foolish moment. Save $80, waste 10 hours of labor.

Checkpoint: Are you willing to invest in and learn LightBurn (or a similar professional software)? If yes, the S1's software ecosystem is a Go. If you plan to rely solely on the free software for production, that's a risk.

Step 5: The Rotary Tool for Cylindrical Engraving

This is the S1's real hidden advantage for my use case. The rotary tool allows you to engrave on cylindrical objects like tumblers, bottles, and wine glasses. For a small shop doing custom gifts or promotional items, this is pure gold.

From my experience doing about 400 custom tumblers last holiday season, the rotary attachment works well. Setup is fiddly—I messed up the first three tumblers because the alignment was off (that's a $45 learn). But once it's dialed in, it's consistent.

The key here is patience. The alignment process takes 10-15 minutes the first time. It's not a 'plug and play' experience. But once it's set, it's reliable.

Checkpoint: If your business involves engraving cylindrical items (drinkware, bottles), the rotary tool makes the S1 a much stronger investment. If you only need flat surfaces, it's a nice-to-have but not essential.

Step 6: Total Cost of Ownership (TCO) Check

Let's be honest. The sticker price is just the beginning. I've tracked over $180,000 in cumulative spending on small production equipment across 6 years. The TCO for the xTool S1 looks like this:

• Machine: $700-$1,200 (depending on module and bundle)
• LightBurn License: $80
• Rotary Tool (optional): $150
• Exhaust System (recommended): $100-$200
• Laser Module Replacements (yearly): $200-$400 (diodes degrade over time)
• Consumables (etching spray, cleaning supplies): $50-$100/month

I'm not including shipping taxes because that varies. But the 'real' cost to get a fully operational setup for production is closer to $1,200 - $1,800, not the $699 you see on the homepage.

Now, is that still a good deal? For a machine that can replace a few thousand dollars in outsourced work, absolutely. Our ROI on the S1 was about 4 months when we started doing in-house tumbler engravings. That's a pretty solid return. But you need to know the full cost upfront.

Final Caveats & Common Mistakes

I've covered the checklist, but a few quick warnings from my own 'lessons learned':

• Don't assume all modules are equal. The 20W vs 40W difference is speed, not cutting depth. For some materials, the 40W cuts 40% faster. For others, only 20% faster. Test before you order a bulk batch.
• Ventilation is not optional. Laser cutting creates fumes. If you're in a workshop, invest in a proper extraction fan. We learned this when our small shop smelled like burnt plastic for a week.
• Read the fine print on 'lifetime' guarantees. Laser modules degrade. A factory 'lifetime' often means the expected operational life, which is 2-3 years for a desktop diode laser. That's industry standard.

That's it. Six steps, six checkpoints. Hope this helps you make a more informed decision and avoid some of the hidden costs I ran into. The xTool S1 is a solid machine for the right use case. Just make sure it's the right use case for you.
