xTool S1 FAQ: What an Office Administrator Learned Before Buying a Laser Engraver

I'm the office administrator for a 40-person company. I manage all our equipment and supply purchases—roughly $60,000 a year across 15 different vendors—and I answer to both operations and finance. In late 2024, I did the research and sourcing for our xTool S1 laser engraver. These are the questions I had before buying, plus the ones other small business owners have been asking me since. Some answers surprised me. Hopefully they save you a mistake or two. Everything here reflects our experience as of January 2025.

1. Is the xTool S1 worth it for a small business?

We ran the numbers before committing, which is kind of my job. We were spending about $5,000 a year with outside vendors for branded mugs, acrylic plaques, and client gifts. The S1 with the basics cost about $1,200, plus another $400 for the accessories we actually needed. After about four months, it had paid for itself. Actually, that's conservative—it doesn't count the rush orders we avoided when a promo vendor quoted a two-week lead time and we needed gifts in three days.

That math only works if you'll actually use the machine—like at least once or twice a month. If it's going to sit in a corner, it's an expensive paperweight.

One thing I appreciated as a small customer: xTool didn't treat our modest order differently. Whether we ordered $50 of test material or the full bundle, the service was the same. When I started managing purchasing in 2020, vendors who ignored small orders were the ones who lost us later. Small doesn't mean unimportant—it means potential.

2. Engraving on metal—can the xTool S1 really do it?

The short answer: yes, with the 2W IR laser module. Without it, not really on bare metal. We tested stainless steel, brass, aluminum, and titanium before we accepted any client work. All four engraved cleanly. The standard blue diode laser alone mostly reflects off polished metal, which is a frustrating discovery to make after unboxing. There are marking sprays that claim to fix that, but we found the results less durable—it's basically a surface coating, not an engraving.

Here's something most people miss: it's not about peak wattage. It's about wavelength. I'm not a physicist, so I won't pretend to explain absorption curves, but the practical difference is obvious. The IR module delivers a wavelength that metal absorbs, so you get a clean mark instead of the beam bouncing off. That matters because you'll see marketing that throws around “40W” as if it solves metal engraving. It doesn't. Per FTC guidelines (ftc.gov), advertising claims need to be substantiated—so test before you trust.

The limit: it engraves metal. It does not cut it. Anyone claiming a desktop diode laser cuts through thick steel is not telling you the truth.

3. What's the deal with the xTool S1 2W IR laser module?

Do I need it? If metal engraving is in your plan, yes. The xTool S1 2W IR laser module swaps into the machine in about 10 minutes—no special tools, just following the alignment guide. What I mean is: it's a different tool for a different material. The standard blue diode handles wood, leather, acrylic, and ceramics well. The IR module is specifically for metals and some harder plastics. Plan for a few minutes of recalibration after each swap, but that's about it.

We initially skipped it to keep the budget down. Then a client asked for steel logo badges, and we ordered it a month later. Looking back, that was false economy. The bundle discount when buying with the machine saved us about 8% versus ordering separately, and we lost two weeks waiting for the module to arrive. If metal work is even a maybe for you, get it upfront. If it's never, skip it and save the money.

4. Can it work as a cup engraving machine?

Honestly, this is where the S1 shines in our office. With the rotary attachment, it works as a cup engraving machine—tumblers, bottles, even cylindrical vases. The rotary holds the cup and spins it under the laser, so you get a clean wrap-around design without manually repositioning the material.

Our most popular internal item is branded stainless tumblers for new clients. Each one takes about 8 minutes at a 300 DPI engraving setting—the same resolution standard used in commercial print—plus a couple of minutes for setup and cleaning. Compare that to the $12–$15 per cup we used to pay a promo vendor, and it adds up. We made back the rotary attachment's cost in about 25 cups.

One lesson worth sharing: alignment on the rotary takes practice. Our first batch had three cups with the design sitting a quarter-inch low. We caught it before anything shipped. Now we spend two extra minutes checking alignment, and it's been spotless since. Trust me on this one—verify your first batch piece by piece.

5. What xTool S1 honeycomb size should I order?

The S1's work area is 420 × 400 mm—about 16.5 by 15.7 inches. The standard xTool S1 honeycomb worktable matches that footprint exactly, so it drops right onto the base without overhang. I want to say the current bundle includes the honeycomb, but xTool changes their offerings pretty regularly, so verify before you order. If you're buying the honeycomb separately, check compatibility with your specific model—the S1 version is different from the ones for other machines.

What I'd tell any buyer: don't skip the honeycomb. We used a flat cutting mat during week one, and the underside of our 3mm basswood had visible scorch marks. The honeycomb's open structure lets air assist flow through and doesn't trap reflected heat against the material. That alone fixed our charring problem. Cleanup is easier too—debris falls through instead of building up on a solid surface.

6. Should I get a CO₂ laser instead?

I did the “co2 laser ideas” search too, so I get the temptation. CO₂ lasers are genuinely good at cutting thicker stock and handling materials that diode lasers struggle with. For a shop cutting large-format acrylic or doing deep cuts in heavy hardwoods every single day, a CO₂ system is a better fit.

But that wasn't us. We needed precision engraving, small-batch personalization, and a footprint that fits in a storage closet. The S1 covers at least 90% of our work. And the maintenance difference matters at our scale: no tube replacement, no liquid cooling setup, just a solid desktop unit.

Here's the thing: don't let anyone tell you CO₂ is “real” lasers and diodes are toys. Both have their place. It's about matching the tool to your workload. And whichever route you go, verify claims with actual test pieces before you commit. Every manufacturer spec is optimistic until proven.

7. What do you wish you knew before buying?

Three things.

First, the accessory budget. Most buyers compare machine prices and completely miss the rest of it. We saved $150 on a third-party air assist because the price felt like a deal. It wasn't strong enough for clean acrylic cuts, so we bought the official xTool one for $180. Net loss: $330 and a week of frustration. The full bundle from the start would have cost less and worked from day one.

Second: ventilation and enclosure are non-negotiable. This is a laser. You need airflow, you need the enclosure, and you shouldn't run it in a room without proper exhaust—especially when cutting plastics or leather. Don't let anyone tell you otherwise.

Third: buy test materials before your real stock. We burned through roughly $50 of scrap plywood and acrylic before our settings were consistent. That's not waste—that's tuition. Learning on cheap material means you don't ruin $200 worth of walnut on day one.

And one more, because it matters: if you're a small business—our company is barely 40 people—don't accept being treated like your order doesn't matter. We've gotten great support from xTool as a tiny account. The vendors who respected our small orders are the ones who still have our business today.
