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.

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.

Excellent

Im extremely happy with the laser. Very easy to use. It only took a very short time to set up and start using. I was engraving in no time. So far, I've made aluminum business cards, slate coasters, dog tags, engraved tools, and engraved some rings with the rotary tool. I couldn't be happier with the unit. Ive purchased virtually every available accessory for it. All the rotaries, the 100 watt fume extractor, and the medium sized safety enclosure. We plan on adding this to our small business.

 I received my laser earlier than anticipated. I was missing the thumb drive with the files on it. I contacted ComMarker. They sent me an email immediately with the files I needed to get up and going. The pictures attached were my first try at doing a photo on a metal business card. (Second day of receiving) A truly superb machine! I can't wait to see how far I can take this!I highly recommend this laser and the company.

I've been testing this machine for a few weeks and it's great the price. I'll attach some pictures and a video to this review. I don't have a lot of space, so I appreciate the compact size.It works very fast on anodized aluminum and leaves a solid black mark on stainless steel if you use the z-marking method (you can see that on the stainless steel dog tags pictures).The machine is well calibrated by default, but you can always get more detailed results if you calibrate it yourself. I followed the instructions of an awesome YouTube video called "FIX your Galvo Laser F-Theta Lens Distortion with Ezcad Corfile", the channel is called Laser Everything, and if you are a new fiber laser user like me, this is going to save your life.Costumer service response time is very good, and they were willing to answer all my questions, before and after the purchase, and I did ask a lot of questions.I feel good about my purchase, if in the future I find any problem I’ll update my review.

Arrived faster than the CO2 laser Im STILL waiting on, every question asked was answered within hours, NOT days. Incredible support honestly. Couldnt ask for more! Maybe just that Lightburn have the same support!

C
Carl W. Price

                  Let's start with the drawback, if you use Linux, this engraver requires a load of the FW over USB before it is recognized. Without doing this, LightBurn couldn't see the device and let you set it up. I found someone on the LightBurn forum that wrote a python script that worked with the windows lmcv2u.sys (32-bit version) that allowed this to load. After that, LightBurn could find the device, and it seems to set it up after that.Once that was sorted, I followed the instructions to get the settings right and have been playing with various things since. I have done stainless steel, copper, brass, anodized business cards, slate, and as the pictures show, rocks from my yard. The initial start-up was frustrating, but the laser itself has been fun.On a side note, the staff at the customer support has been helpful and looking to improve, hopefully they will provide the files needed to get this set up easier in the future. But their communication has been a plus in my eyes, and what brought this from a 4 star to a 5 star review.Now onto my thoughts on the engraver. The details it produces are out of this world. This is does such a good job engraving, the rocks in the picture are sitting on paper towels, you can see they aren't that big, yet the detail is stunning. Adjusting the height is really easy, for a introduction to fiber lasers, this is a great unit.
