FAQ

1.What Materials Can Be Engraved Using ComMarker's B4 30W Fiber Laser Engraver Machine?

The ComMarker B4 30W Fiber Laser Engraver Machine is versatile, capable of engraving a wide range of materials, including metals, hard plastics, stone, leather, and more. This adaptability makes it a powerful tool for various industries, providing high-quality results with precision.

2.What's the Difference Between B4 and B4 MOPA?

The main difference between the B4 and B4 MOPA models lies in their laser technology:

  • Q-Switch: Features a non-adjustable pulse width, with a frequency range of 20kHz – 100kHz. This is suitable for high-speed engraving on metals without color variations.
  • JPT MOPA: Offers a pulse width of 1-500nm and a frequency range of 1kHz – 4000kHz. The MOPA laser is superior for engraving colors on stainless steel, titanium, black on aluminum, and plastic without burnt yellow color, providing greater accuracy.

The B4 MOPA is ideal if you require color marking on metals and high precision, while the standard fiber laser is better suited for straightforward, high-speed metal engraving. Price and work effect vary significantly between the two models.

3.How Long Does the Laser Source Last in B4 30W Fiber Laser Engraver Machine?

The laser source in the B4 30W Fiber Laser Engraver Machine has a lifespan of over 100,000 hours, ensuring reliable, long-lasting performance.

4.What Software is Included with the B4 30W Fiber Laser Engraver?

The B4 30W Fiber Laser Engraver comes with EZCad software and is compatible with LightBurn software (not included). This provides a comprehensive suite of tools for managing engraving projects efficiently.

5.How Large is the Work Area Provided by the B4 30W Fiber Laser Marker?

The B4 30W provides a 4.3×4.3 inch (110×110 mm) and 7.8×7.8 inch (200×200 mm) field for various project sizes. Additional lenses ranging from 70mm to 200mm are available upon request to accommodate different engraving needs.

One of the best values for a fiber laser!

The B4 50W Q-switched laser strikes an excellent balance between performance and cost.

At first I was concerned that it used a MAX laser source since a lot of people recommend avoiding MAX. Since the price was very good, I looked for the primary reason behind the lower recommendations and found that it was due to the historically low frequency range of the MAX Q-switched lasers compared to other Q-switched lasers. When I looked at the specifications on the ComMarker site they didn’t seem to match the specifications from older reviews I had read. I asked ComMarker for the specific model number and they provided me with a sample copy of a test report that gave me the model number and tested specifications. It turns out they are using a newer model of the laser module and I was able to verify the specifications from the MAX website and another MAX distributor website. It is a better version than their older models and is now more comparable to its competitors. For those curious I’ve attached a picture of my test report.

With that settled, I pulled the trigger and ordered it. Just after I ordered the chaos of the tariff changes began. I contacted ComMarker and they assured me they would be able to fulfill the order at the price I paid and that taxes and duties would be included.

Once it shipped I received it from overseas about three days later. Everything was packed well and arrived in perfect condition. Between the assembly video and manual they provided I was able to get the laser setup quickly and perform some initial tests.

I ended up deciding to build an enclosure so that I could customize it to suit my needs and fit my work space. I look forward to using the B4 more often once I am able finish the enclosure and ventilation system and would definitely purchase from ComMarker again, with the Omni 1 being high on my list.

Omni 1 - 10 Watt version

I am very impressed with the setup and quality of the liquid cooled version of this 10 Watt UV laser. Set up was mostly easy. I had to calibrate the lens, but that was easy using LightBurn. I just wish they had the red laser preview like on the B6 model and maybe the auto-focus too.

Professional Laser

Needing a laser to enhance my CNC business, after extensive research, the Commarker range hit the mark from support to range. Ultimately opting for the B4 50w to compliment the metal work I do.
I have not been disappointed and the support from Commarker when approached has been brilliant.

Protect a cat enclosure arrived

Bought the enclosure for my omni1 to protect my very inquisitive little cat. She can’t wear the excellent goggles/ glasses supplied. The enclosure is illuminated by LED surface mounted lamp access through protective door is good. Assembly is easy but loads of screws. Main materials aluminium and acrylic all securely bolted together. It works well.

You know you have a good laser when you cant think of a single bad thing to say about it. Ive enjoyed the increased speed, power and potential. I also got the D80 rotary and thats one solid piece of machinery, also easy to use. I recommend this laser.

Received my fiber laser very fast. Once received everything worked great but the automatic focus adjustment did not work. Commarker was very responsive to my e-mail and fixed the problem. Laser works great and I am very happy with my purchase.
