20W Desktop Laser Engraver Machine DIY Laser Logo Mark Printer for Metal Engraving and Deep Wood Engraving

Was not worth 200.00.. think I’ll return it..

I was expecting to have to do a lot more assembling of parts when I ordered it, but it was actually nearly complete right out of the box! All you have to do is mount 1 assembly, put on 4 screws, and attach 2 cables and then 2 more screws and a cable for the laser itself and it was all set.{doesn't matter which laser you have} But there was one problem with the hardware in that the USB cable they provided was bad. It was the original {now old fashioned} large connector size USB cable type. Most USB cables you see today are micro or mini, but this one was the most basic USB cable, the first kind ever made. But KKmoon gave me a very thin, obviously untested, and very short version of this cable that did not work. Of course I had several in my office, and one of my old 6 foot cables worked just fine {the bad one was so small I would have replaced it anyway}. So if you follow all the software instructions and it cannot find the laser, try a different USB cable. I used an old computer, one I intended to dedicate to the machine that even had Windows 7 on it, so it needed a .net upgrade to a version above 4. Then you need to install the driver, and they don't make that too obvious in the instructions but you have to have it install the USB channel 341 {or something close to that} port software. Then you need to plug in the USB cable and plug in the laser's power cable so it lights up. Then you need to actually run the software they had you download and it has a handy little test interface window that shows you the process of discovering the laser over USB on that channel. Once that test completes and the test window disappears, the laser will actually come to life and the motors will move the laser to its zero axis point. Note that the laser will be on even if you just plug in the power with no computer, but it's just like a little laser pointer and it won't hurt you unless you look directly into the lens. DO NOT LOOK INTO LASER EVER!!!! You can pick your pattern out of their library, or put one in their collection folder and use that, then you get a chance to add text and move the pattern around in the plane the laser can hit. Once you OK that you get to the point where you can actually cut or engrave something by hitting the play button. But use the box button first, that shows you a rectangle with the laser of exactly where it is going to carve so you can situate the material you are engraving under the laser properly. Note also that when the laser starts carving or engraving, those little motors will whip that laser back and forth very quickly, and the force of that movement can move the whole laser frame, so you really need to screw it down somehow. One last important note: on that last window with the big play button there are 2 other sliders that are very important! One is the laser power percentage, and since I have the 20W laser, I put it at 20% which burns nice and deep on wood I have used. The other very important slider on that window is the dwell time on the very bottom which controls how long the laser will sit on each dot and burn it in. My 20W laser only needs 3-4 milliseconds to make good carvings, but if you have a smaller laser you might need to turn that up to get deeper cuts. But these two settings are important because they control the effective power of the laser. Other folks said the 20W was only for cutting, but it is not true, you can easily dial back the power with those settings. One last note: WEAR THE GLASSES THEY GIVE YOU BEFORE YOU PUSH THE BIG PLAY BUTTON THAT STARTS THE MACHINE CARVING! You don't need them when you are setting up, but you will when it is actually carving stuff! Good luck and God bless.

Before I bought this engraving machine, I consulted the customer service in detail. She sent a video to me. When she knew that I was going to use it for cutting, I was suggested to buy 20W power, she said the cutting effect would be better

I'm really surprised, the laser makes a super laser engraver A laser engraving machine where the price-performance ratio is more than justified. I have to say I'm just thrilled.
