Size: 45W with Laser Coolant
The CO2 laser has all the bells and whistles you need. Even has Safety latches, if you open a door the laser stops burning. Designed with the user in mind. Cuts as advertised and is far better than my old K40.

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.

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

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.

So far, not impressed. The machine arrived. I just got to unboxing. It’s dented. Next, two loose nuts on the bottom of the machine that fell off while moving it in place. These hold the power supply in place. The gantry is not aligned properly either. Cables not plugged in, data cable port not soldered to the laser currency display. Loose parts inside. Who quality checks these things? I get it, it’s not super expensive. I’m just trying to expand my small business a little by adding a CO2 laser. Yes, I use lasers already. If you’re going to make a product, don’t make people fix the machine prior to use. I think I’ll be requesting a replacement.

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

Mad Skills most definitely required. I knew going in that the assembly of these was shoddy at best but....wow. Out of the box the X axis was nearly unmovable. Had to remove the gantry entirely, disassemble it, unwarp it and then reassemble it just to gain movement. The Y axis bearing is horribly noisy and unlikely to last long. Plenty of stripped screws had to be replaced with better hardware. The red dot laser was not wired in....the ends were barely just pushed into a connector and fell out as soon as it was touched. The inside of the cabinet was dirty as are the mirrors and lens. Hopefully the tube is fine...going to be a bit of work to get this to the point of ven applying power. If you love fixing things, redesigning things and wondering how any of this can pass any quality assurance process then this is your baby. Edit: After several days of checking all connectors, repairing those found to be poorly crimped, etc., repairing the most glaring issue of no proper ground, replacing most of the screws on the gantry and mirror, reinstalling both temp meters because they fell out and aligning the mirrors it actually runs. I was able to confirm it is operational, laptop and k40 Whisperer can indeed control it. So in a nut shell....be prepared to rebuild this unit. It's a good parts kit, the case is good, tube is fine. Electrically dangerous until properly modified but....it will cut and engrave with a little work. You should be comfortable with soldering, mechanical skills, electrical skills and have a Macgyver Engineering degree.
