FAQ

1. What materials can be engraved using ComMarker's B4 20W fiber laser engraver?

The B4 20W fiber laser engraver can engrave various materials including metals, hard plastics, stone, leather, and more.

2. What's the difference between B4 and B4 MOPA?

The main difference lies in their parameters:

  • Q-switch: Pulse width is non-adjustable, frequency ranges from 20kHz to 100kHz.
  • JPT MOPA: Pulse width ranges from 1-500nm, with a frequency range of 1kHz to 4000kHz.

MOPA technology offers superior results, especially in color marking on metals like stainless steel and titanium, and provides better accuracy on plastics. For users who only need to engrave metals at high speed without color, the standard fiber laser engraver is sufficient and more cost-effective.

3. How long does the laser source last in the B4 20W fiber laser engraver?

The laser source is designed to last over 100,000 hours, ensuring long-term performance.

4. What software is included with the B4 20W fiber laser engraver?

The engraver comes with EZCad software and is compatible with LightBurn software (not included).

5. How large is the work area provided by the B4 20W fiber laser engraver?

The B4 20W fiber laser engraver offers work areas of 4.3×4.3 inches (110×110 mm) and 7.8×7.8 inches (200×200 mm). Additional lenses ranging from 70mm to 200mm are available if needed.

Safety Enclosure works as expected

We received our safety enclosure, but the top was damaged during shipping. I contacted their support, and it was handled immediately. We received a new top replacement piece and it's all working great.

Satisfaction

Originally, I had a 20W diode laser.
Then I decided to purchase a ComMarker MOPA 60W.
Encouraged by the easy purchase process and the usability of the IR engraver, I also bought a 5W Omni1. I haven’t tested all of its features yet, but everything I have tried so far has worked flawlessly. I can recommend these models to any DIY enthusiast.

One Laser to Do It All in 2025? The OMNI1 Might Be It

I started laser engraving back in 2021, and the progress in just a few years has been incredible. Prices have dropped, and high-end laser technology that used to be out of reach for small businesses and hobbyists is now more accessible than ever. When I first got started, you needed multiple lasers to cover different materials. But in 2025, with just one or two machines, you can handle almost anything you want to engrave. The OMNI1 UV laser is a game-changer. It covers such a wide range of materials that for many people, it could be the only laser they ever need. One of my dream capabilities was glass engraving — and this UV laser not only handles glass beautifully but also delivers stunning high-definition images that truly blew me away.

Good machine (50w b4)

Overall this galvo fiber laser is very good. But I do not recommend the enclosure (the PMMA plate is good) or the ventilation systems that are also sold (not enough draw). All the quality goes into the laser and it's rotaries but past that you should consider making your own enclosure, buying saftey glasses from a different provider(frame quality), and setting up an in-line ventilation system. The laser itself performs very good and does exactly what it was advertised to do. Customer service was also quick and helpful before and after purchase.

In short, buy the laser and rotaries but DiY a proper in-line ventilation system and enclosure for saftey.

4 stars, laser is great, accessory products need a little work. Overall happy with everything.

A wonder at low cost

Assembly take 10 minutes. 30 minutes after, i was engraving a picture of my wife on a stainless steel plate. The result, the details were mindblowing. This thing is fast and accurate. And, thats my first time, never use a laser before.
