As someone new to CO₂ laser technology, I initially found the setup process quite challenging. My primary goal was to cut acrylic, but I quickly realized I had a lot to learn. Fortunately, OMTech's customer service was exceptional—they provided clear answers to my questions and ensured I felt supported throughout the process. One standout moment was the video consultation with a technician, who patiently guided me through the alignment procedure. That hands-on walkthrough completely clarified what had seemed so confusing at first, and I was able to properly align the laser with confidence. Having transitioned from a diode laser to a CO₂ system, I couldn’t be happier with the upgrade. The machine performs beautifully, and I’m excited to explore its full potential as I continue growing in this craft.

Great product - after 2 hours of not working realized that we had the water hoses on backwards. Then boom it worked amazingly.

Works well. Easy to set up. USB cable was bad, which is an easy fix (once I figured that out). Would be 5 stars if the USB worked.

Love my laser. It has been great to use. I did upgrade and get a chiller because it seems to run warm even in a cold room.

The OMTech K40+ (Plus is important) is not the cheapest K40 around. But this is because its packed with a bunch of features you'd otherwise have to sort for yourself if you bought one of the cheaper models: -Upgraded GRBL compatible control board so you can use Lightburn right out of the box. -Contact sensors that prevent the laser from firing when the lid or collection tray is open -Honeycomb bed. -Adjustible height lens so you can get the correct focal point without having to raise or lower the bed. -Included led light so you can see your progress -Height-adjustable feet to level the machine - Other options I've surely forgot to mention If I had to ding the machine for something, it would be the positioning of the collection drawer contact sensor. If the collection drawer is out even by a hair, the laser will refuse to fire and you may not know why. I wasted quite a bit of time trying to troubleshoot my laser not firing without any feedback that the answer was very simple, nudge the drawer in a bit. I can foresee a situation where vibration could also lead to it sliding out in the middle of a job. As long as you know about it, its not that bad of an issue.

Arrived well packaged, had a slight issue but omtech fixed it without delay. Pleased so far. My unit did come with a rotary despite what another review said. It was packaged separately to keep it from thrashing during shipping and the UPS driver left the packages in different locations

damaged from factory -- not shipping. they offered me a partial refund to deal with it. much less than my hourly rate, and lost a half day at the shop fixing my brand new k40+... fyi -- 5 years of experience with these machines. i wouldn't hesitate to pay MORE to buy the old libusb model if they still made it

Pros: low cost, high power CO2 laser Cons: did not arrive in working order, with multiple manufacturing and assembly defects. (See clearly mis-wired power supply) Support was responsive but ultimately unhelpful. I ended up working through most of the problems on my own. Only buy this laser if you are comfortable diagnosing and repairing it yourself.
