It works exactly as it should straight from the box.

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.

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.

It works but there are better machines for less money. I doubt that it is the power stated. Probably more like 30 watts. Very small work area. But I knew that going in. Won't know for a little while about durability and longevity. Customer service is slow to respond. If you are looking for a quality machine, I would look elsewhere.

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

Took a few hours to get mirrors all aligned. Once done went to check z axis and wouldn’t fire through lens. Took off lens part to check and beam was centered. Checked lens and the o ring was missing and lens had a crack. Waiting to hear back from support. Sent pic of Lens and they said it looked fine. Sent pic again with arrow pointing to crack and haven’t heard back. Company did finally send a new lens and o ring for lens. Works great now.
