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.

Awesome 30 watt Mopa Laser!!

This was my very first laser purchase, so I started from scratch going down the long road of educating myself about the various types and brands of machines available. This was a major purchase for me so I was very careful about making the right choice. Ultimately I settled on ComMarker. I’m very pleased with my new 30 watt JPT mopa laser, ComMarker in my opinion offers the best value… hands down! I’m already planning my next laser… the Omni 1.

Antonio Estevez
very good

this machine is so good the colores are very amazing 100 recommended

So far, great!

The laser is doing a great job so far. Doing some material testing still. My only observation is the type of power button. A up/down toggle or something that does not push in might be better. But no big issues at the moment.

Andy
Easy to set up and get going.

I have zero previous experience with lasers yet with a bit of online research and the associated notes I had a piece of Aluminium engraved.

Even Better If:
- After Initial build calibration is needed for bulge, ratio and skew. This should be a recommended first step.
- to support your English speaking market I would enlist an English speaker to create you a comprehensive installation and calibration instructions in English.
- I would provide the screen as standard.
- a gauge on the column to indicate lens height position.
