Commarker Lasers: 7 Honest Answers After 4 Years of Trial & Error

What This Article Covers

I run a small custom engraving shop—been at it since 2021. Over four years, I've burned through more material than I care to admit, made about $3,200 worth of avoidable mistakes, and tested three different laser brands in the process. This FAQ covers the questions I had when I was starting out, plus a few I should've asked.

1. Is Commarker actually good? How does it stack up against xTool?

When I first started looking at laser machines, I assumed the biggest brand with the most marketing was the safe bet. So I almost went with xTool—their ads are everywhere, the community is huge, and the packaging is slick. But here's what I didn't realize back then: "biggest" doesn't mean "best for your specific use case."

Commarker competes well with xTool in several areas, especially if you're running a small business rather than just a hobby setup. The key difference? Commarker offers a wider range of laser types—fiber, UV, MOPA, CO2—under one roof. xTool focuses mostly on diode and CO2 for hobbyists and light commercial use. Commarker's B6, for example, is a 60W CO2 that handles a broader material range than xTool's equivalent models at a similar price point. But I'm not gonna pretend Commarker is the perfect fit for everyone. If you want a plug-and-play ecosystem with tons of pre-made templates and a large online community, xTool might serve you better. If you're okay with a bit more hands-on setup in exchange for better specs and lower cost, Commarker is worth a hard look.

I've run both. I currently use a Commarker B6 and an Omni1. I don't regret the switch.

2. What's the real cost of a Commarker B6? (Not just the sticker price)

Alright, let's talk money. The Commarker B6—that's their 60W CO2 model—is listed around $1,800 on their site (as of March 2025). But almost nobody pays full price. Commarker runs frequent discounts—I've seen 15% to 25% off if you catch the right time. I paid $1,460 for mine during their Black Friday sale. (Should mention: that didn't include shipping, which was about $90 to my location.)

But the real cost? That's where my initial misjudgment cost me. I only budgeted for the machine. Here's what I didn't factor in:

• Shipping and handling: $90–$150 depending on location
• Extractor/fume system: another $250–$500 if you don't have one
• Material testing: I easily spent $200 on scrap material in the first month figuring out settings
• Software: LightBurn license is $60–$120, and it's worth every penny

So all-in, my B6 cost closer to $2,000. Still competitive—but don't make the mistake I did and assume the machine price is the only number you need.

3. Can a Commarker laser actually cut steel? I tried so you don't have to

This one hurt. Early on, I saw a YouTube video of a fiber laser cutting through thin steel and thought, "My Commarker can probably do that." Spoiler: it depends entirely on which machine you're talking about.

Commarker's CO2 lasers (like the B6 or Titan) cannot cut steel. They'll mark it with a coating, and they can engrave it with the right settings, but cutting? No. The wavelength of CO2 lasers isn't absorbed by metal in a way that allows clean cutting. I learned this the hard way on a $3,200 order of steel nameplates—I ruined three sheets before I admitted defeat. That mistake cost me $450 in material and a 1-week delay.

Now, Commarker's fiber lasers (like the Omni1 or their MOPA series) can cut thin steel—we're talking up to about 0.5mm to 1mm depending on the power. I've cut stainless steel shims and thin steel tags on my Omni1 with good results. But if you're trying to cut 3mm steel plate, you need a dedicated fiber laser in the 500W–1000W range, which is a completely different price bracket. Commarker doesn't really target that market.

So: cutting thin steel with a fiber laser? Yes, possible. Cutting steel with a CO2 laser? Don't bother. (Note to self: I really should make a video showing the failed attempts so others can see what not to do.)

4. How do I laser engrave a photo on wood without turning it into a mess?

Oh man, this was my first big mistake. I wanted to engrave a high-contrast portrait on a walnut cutting board for a customer's anniversary gift. I loaded the photo straight in, hit "engrave," and got a black blob that looked like a shadow monster. That board went straight in the trash.

Here's what I learned after ruining about $60 worth of wood samples:

• First, convert your photo to grayscale. Sounds obvious, but you'd be surprised how many people skip this. Use an image editor (GIMP is free) to remove color information.
• Crank up the contrast. Photos that look fine on screen engrave flat unless you boost contrast by 20–30%. The laser reads grayscale values as power levels—low contrast means muddy results.
• Dithering matters more than you think. I use Jarvis or Stucki dithering in LightBurn for wood. Floyd-Steinberg works too, but I've found Jarvis gives smoother gradients on darker woods.
• Do a material test grid first. Seriously. Run a small test with different power/speed combos on the same wood type before you touch the final piece. I learned this after ruining a $45 slab of cherry.

I'd say I have about an 80% success rate now on photo engravings. The other 20%? Still learning. (If someone has tips for engraving very light woods like maple, I'd love to hear them—I've never fully figured that out.)

5. What materials can Commarker handle—and what's off-limits?

This is the question I wish I'd asked before my first purchase. I assumed "laser engraver" meant "works on everything." Nope. Here's the rough breakdown based on my experience:

CO2 lasers (B6, Titan, etc.):

• Excellent: Wood (all soft/hard types), acrylic, leather, paper/cardboard, fabric, glass (with coating)
• Good: Stone, marble, ceramic (marking/engraving only)
• Skip: Metal (unless coated), PVC (toxic fumes), polycarbonate (burns yellow)

Fiber lasers (Omni1, MOPA series):

• Excellent: Metal marking/engraving (steel, aluminum, brass, copper), plastic marking
• Good: Thin metal cutting (up to ~1mm), some ceramics
• Skip: Wood (fiber lasers don't work well on organic materials), acrylic, leather

Honestly, I'm still figuring out some materials. Every batch of wood is a little different, and I've had two identical-looking acrylic sheets behave completely differently under the same settings. Material consistency is a whole topic on its own.

6. Which Commarker model should I start with? (B6 vs Omni1 vs Titan)

I get asked this a lot. And my answer is usually: it depends on what you're actually going to make, not what sounds coolest.

Commarker B6 (60W CO2): This is what I'd recommend for 70% of small business beginners. It cuts wood up to 10mm, engraves acrylic beautifully, handles leather and fabric, and has a decent work area (400×400mm). If you're doing signage, gifts, or custom decor, this is your machine. I started with a cheaper diode laser and upgraded to the B6 within 6 months. Should've just bought the B6 first.

Commarker Omni1 (Fiber): Get this if your main business is metal marking—jewelry, tools, industrial tags, firearm engraving. It's a fiber laser, so it won't cut wood, but it'll mark metal all day. I use mine for stainless steel tumblers and aluminum parts.

Commarker Titan (CO2, higher power): This is for thicker materials and larger batches. If you're cutting 12mm acrylic or running production volumes, the Titan's extra power (100W+) makes a difference. But for a beginner? Overkill. I'd start with the B6 and upgrade if your volume justifies it.

One thing I'll say: don't overbuy on power thinking it'll "future-proof" your shop. I made that mistake with my first purchase. Get the machine that fits your actual projects for the next 12 months. You can always upgrade later.

7. What's the biggest mistake new buyers make?

If I had to pick one mistake that hurts more than any other—it's this: people buy a laser without understanding the material they need to process most. They see a machine that can "do everything" and assume it'll work perfectly out of the box. Then they're frustrated when it doesn't cut steel or can't engrave glass as deep as they'd like.

I did the same thing. I bought a cheap diode laser thinking I'd figure it out later. Within a month, I realized it couldn't cut clear acrylic (diode lasers pass right through) and couldn't mark metal without special coatings. That was a $350 mistake, plus the cost of ruined material.

So here's my honest advice: write down your top three materials. If you're mostly working with wood and acrylic, get a CO2 laser. If you're mostly marking metal, get a fiber laser. If you need both, consider having two machines—or pick one that covers 80% of your work and outsource the rest. It's not glamorous advice, but it'll save you money and frustration.

(Oh, and another thing: whatever machine you get, budget for a good exhaust system. I skipped this at first and regretted it within a week. Your lungs are worth more than any laser.)
