The Real Reason I Bought the xTool M1 Ultra Instead of a CO2 Laser 80W

I manage a small workshop that takes on custom engraving and short-run production. In late 2024, I was ready to buy a CO2 laser 80W. After all, that's what everyone says you need for acrylic and wood. Instead, I bought the xTool M1 Ultra 4-in-1 craft machine. Here's why I think that was the right call—and where I'm still not totally sure.

My First Mistake: Chasing Power Without Asking About My Actual Work

I almost made the same mistake I see a lot of workshop owners make: buying more laser power than we could actually use. A CO2 laser 80W sounds impressive. It cuts faster, and it handles thicker materials. But here's the thing I learned the hard way—our backlog is mostly thin wood, acrylic nameplates, and the occasional metal tag. Thick cutting jobs are maybe 5% of our revenue. I was about to spend three times my budget on a machine that would sit idle most of the week.

So I started asking a different question. Instead of "What's the most powerful laser I can get?" I asked, "What's the most versatile machine that actually fits the jobs we take?" That's how I landed on the xTool M1 Ultra.

Why the 4-in-1 Design Changed My Mind

The M1 Ultra isn't just a laser engraver. It's a 4-in-1 craft machine—it does laser engraving, laser cutting, blade cutting, and it has a rotary tool attachment. That sounds like marketing fluff until you have a day with three different order types.

Let me give you a concrete example. Last Tuesday we had:

• 15 wooden signs needing engraved text
• 40 acrylic keychains that needed cutting
• 10 leather patches that needed precision cutting—but laser cutting would leave scorched edges

With just a CO2 laser, I'd have burned the leather edges or spent 20 minutes manually cutting each patch with a knife. With the M1 Ultra, I switched the laser module to the blade-cutting mode and honestly, it worked better than I expected. The blade cut the leather cleanly, no scorch marks, no melted edges. I didn't need to switch machines or outsource.

That's the part that doesn't come through in spec sheets. The 4-in-1 versatility isn't about having a gadget that does everything poorly. It's about having the right tool for each job without buying three separate machines.

The Metal Engraving Surprise

Here's the thing I genuinely didn't see coming. I bought the M1 Ultra expecting it to be great on wood and acrylic. That's what all the marketing says. But metal engraving? I assumed I'd need a fiber laser for that—like the CO2 laser 80W can't do it, so why would a diode laser?

Then I tested the M1 Ultra on a stainless steel tumbler with the rotary attachment. It wasn't perfect on the first try. The settings I used left a faint mark that wiped off with a cloth. But after adjusting the power and speed—and using the right marking material—it produced a permanent, dark engraving. Not as fast as a fiber laser, but for our small batch of personalized tumblers, it was more than adequate.

Honestly, I'm not sure why the diode laser performs this well on metal. My best guess is the combination of focal distance and the specific diode wavelength makes it work better than the old diode lasers from a few years ago. But if someone has a scientific explanation, I'd genuinely love to hear it.

What the CO2 Laser 80W Crowd Won't Tell You (Because I Almost Learned the Hard Way)

Let me be clear: CO2 lasers aren't bad. They're actually excellent for specific things. But there are hidden costs that nobody mentions in the YouTube comparison videos.

First, the CO2 tube itself. It's a consumable. Depending on usage, a CO2 laser tube lasts roughly 1,500 to 3,000 hours. A replacement tube for a decent 80W CO2 unit runs anywhere from $250 to $600 depending on the brand, and you either install it yourself (which involves high-voltage electronics and re-alignment) or pay a technician. I've had friends in the industry blow past their tube hours and suddenly face a $400 repair bill plus a week of downtime. That's not a rare experience—that's a normal experience.

Second, the ventilation requirements. A CO2 laser 80W produces significantly more fumes and smoke than a diode laser, especially when cutting acrylic. You're not venting through a small window filter. You need a proper exhaust system, often with a blower rated for high static pressure. That's another $200–500 in setup costs that people forget when they compare base prices.

Third, the learning curve. Chiller setup, mirror alignment, lens cleaning, gas flow adjustments—there's a reason CO2 laser users have long checklists. The M1 Ultra needs less of that because the diode module is solid-state and doesn't rely on CO2 gas or a complex optical path. I'm not saying it's maintenance-free. But I am saying that, for a small workshop, the maintenance burden adds up to real money.

For reference, based on publicly listed prices from major online laser vendors (January 2025), a basic CO2 laser 80W setup typically costs $2,500–$4,000 including a basic chiller and exhaust fan. The xTool M1 Ultra 4-in-1 craft machine with the rotary attachment runs around $1,500–$2,000 depending on the bundle. That gap matters when you also need to buy materials and test different settings.

That's not to say the M1 Ultra is "better" than a CO2 laser in absolute terms. It isn't. If I ever start doing daily production cuts of 1/2-inch acrylic or thick hardwood, I'll probably need a CO2 laser or a fiber laser. But I refuse to pretend that an 80W CO2 is the right choice for a shop that mostly does engraving and thin materials. It's overkill.

The Hidden Cost I Didn't See Coming: The Honeycomb Bed

One thing that caught me by surprise: the honeycomb work table. It's not included in the base package? Or rather—actually, it is included? Let me be more precise. The basic M1 Ultra comes with a standard platform, but for cutting, you really want the honeycomb panel because it allows smoke to escape underneath and prevents reflection off a solid metal base.

I initially skipped the honeycomb bed to save money. That was a mistake. On my first acrylic cutting test, the plastic sagged and warped because there wasn't enough airflow underneath. I quickly ordered the xTool M1 Ultra honeycomb panel. That extra $40–60 should have been factored into my budget from the start.

It also revealed a pattern I've seen in other industries: the base machine price is rarely the total. With CO2 lasers, it's the chiller and exhaust. With the M1 Ultra, it's the honeycomb bed and rotary module. Neither approach is dishonest—but you should ask "what else do I need?" before you commit.

Color Laser Engraving on Wood: The Feature I Didn't Think I'd Use

This one surprised me. The M1 Ultra supports something called "color laser engraving on wood." It's not full-color printing; it's more like creating color marks on certain coated or treated materials. I dismissed it as a gimmick. Then a client asked for a wood sign with a colored logo. Normally, I'd send it out to a UV printer or use a vinyl overlay. Instead, I tested the M1 Ultra's color marking capability.

It took a few tries and a lot of parameter testing, but the result was… actually decent. The color isn't as vivid as a UV printer, but for a rustic wood sign, it had a natural, embedded look that the client loved. And the cost per piece was basically just the material and the laser's power consumption, which is minimal.

I've seen forum threads asking "can xTool M1 Ultra do color engraving on wood?" and the answers are usually vague. I'll give you my answer: yes, but with caveats. The range of colors is limited and you'll need to experiment with your wood type. Different woods react differently—oak gives a warmer tone, birch is more neutral, and some oily tropical woods just don't cooperate. Test on scrap before you risk a customer order.

What Is a Plasma Cutter? (And Why It's Not Relevant Here)

I mentioned to a friend that I was writing about why I chose the M1 Ultra over a CO2 laser, and he laughed. "You know what else you could look at? A plasma cutter." He was joking, but it actually highlights an important lesson: you need to understand what each tool category actually does before comparing them.

So, what is a plasma cutter? It's a tool that uses an electrically conductive gas (plasma) to cut through electrically conductive metals like steel, stainless, and aluminum. A plasma cutter works by sending an electric arc through a gas—typically compressed air—which turns that gas into plasma. The plasma reaches temperatures around 40,000°F or more, which melts the metal, and the high-velocity gas blows the molten metal away.

That's completely different from laser engraving or cutting. A plasma cutter is for thick metal fabrication, not fine detail or wood. It leaves a wider kerf and a heat-affected zone. It's not a substitute for a craft laser. And it shows why I need to be clear about my own use case: I don't cut 1/4-inch steel plates. I engrave wood and cut acrylic. The M1 Ultra fits those tasks. A plasma cutter would be useless to me.

If anything, this exercise taught me to look at the actual process before buying any tool. The question isn't "Is this the best machine in its class?" It's "Is this the best machine for the specific jobs I run every week?"

Objection: "But the M1 Ultra Cuts Slower Than a CO2 Laser 80W"

Yes, that's true. The M1 Ultra is slower on thick cuts. If I were cutting 300 acrylic keychains in one batch every day, the CO2 laser would win. But our batch sizes are smaller. For a run of 20–50 pieces, the speed difference is minutes, not hours. And the M1 Ultra's ability to switch to blade cutting for materials that can't tolerate laser heat saves more time than the laser speed difference costs.

I'll also note that the M1 Ultra lets me leave both the laser and blade modules attached. Switching between modes takes less than a minute. That's a real workflow advantage for a small shop where every hour counts.

Bottom Line

I'm not telling you that the xTool M1 Ultra is the best craft machine for everyone. If you run a dedicated laser cutting business with constant production volume, look at a CO2 laser or a fiber laser. But if you're a small workshop that needs flexibility—laser engraving, cutting, blade cutting, rotary engraving, and even partial color marking—the M1 Ultra deserves a serious look before you spend more money on a single-purpose laser.

It's not perfect. The software sometimes has a mind of its own. The honeycomb bed should really be included in the base price. And I wish the documentation included more recommended settings for different wood types. But I've had this machine for a few months now, and I haven't once wished I'd bought the CO2 laser 80W.

Price transparency matters too. I've learned to ask "what's NOT included" before "what's the price." The CO2 laser's total setup cost is often 50–60% higher than the base advertised price once you add the chiller, ventilation, and tube replacement reserve. The M1 Ultra's additional costs are smaller and more predictable. That alone is worth something—especially when you're running a business on narrow margins.

At the end of the day, my advice is simple: don't buy the most powerful machine. Buy the one that makes you money on the jobs you actually have. For me, that was the xTool M1 Ultra.
