01-03-2019 The neje laser engraver software download is developing at a frantic pace. NEJE DK-8-KZThe NEJE DK-8-KZ laser engraver is great for precision engraving on wood, plastic, bamboo, rubber, leather, or to cut paper and foam. But still, there’s a certain thrill in exploring the cutting edge, and I’ve been looking for something new to get excited about as of late.But given the fact that you can get one of these little guys for around $70 USD shipped, it’s hard to complain.NEJE, as a new coming brand of a mini DIY laser engraver, has a diversified product line, such as various power (from 1000mW to 20W power input) mini laser engraver, laser modules controller boards. In fact, it’s specifically sold as an engraver. At only 1W, there’s no question this device isn’t going to be cutting a whole lot. In the course of looking up diode-powered laser cutters, I came across the NEJE DK-8-KZ. Lasers seem like an interesting next step in my quest towards complete in-house fabrication capability, so I started researching cheap setups to get my feet wet. Software downloads and updates 2019.
![]() Not to say it could be called substantial by any stretch of the imagination, as it stands just under 8 inches tall. And then connect to.So what kind of laser do you get for $70? Let’s find out… HardwareMade of black laser-cut acrylic and held together with stainless steel cap screws, the DK-8-KZ has the look of something that was built from a kit but with good enough fit and finish that it doesn’t feel cheap. Downloading Laser Engraving and Cutting Software V7. Plus, if I’m being totally honest, I wanted to start on something on the lower end of the power spectrum because I’m terrified of blinding myself.NEJE Master aka NEJELaser Master aka KKmoon Laser Engraver is a family of cheap. Now I wasn’t 100% sure what I would do with a laser engraver, but I thought it would be a good way to test the waters before putting serious money (and time) into something more powerful. Neje Laser Engraver Software Full Of LargelySee if you can find something older!)The NEJE DK-8-KZ does come with a disc that has drivers and software for the device, but I promptly threw that in the trash. (Editor’s Note: we tried to find the earliest occurrence of such a device on Hackaday, and came up with this machine. I get the impression that a warehouse full of largely-obsolete optical drives was found in China, and somebody had the brilliant idea of using their accurate motion as the basis for a whole line of tiny laser engravers. There’s also a setting for how long you want the laser to burn for, which becomes important when dealing with different materials. After connecting to the hardware, you load up a 512 x 512 black and white image and adjust the scale and rotation controls as necessary. It even has a command line interface if you don’t want to use the Qt front-end.The workflow is pretty simple with EZGraver. It’s open source and works on Linux, Windows, and OSX. Luckily, the NEJE DK-8-KZ has a relatively simple control protocol and there are a few projects out there to get it up and running.Personally, I’ve been using EZGraver and have had excellent luck with it. But more practically speaking, I don’t have a Windows computer anymore so it wouldn’t have done me any good. Dots indicating where the focal point was while focusingFirst, powering the thing. But there’s still a few things that need mentioning if you decide to walk down this path. AnnoyancesI don’t want to beat up the NEJE DK-8-KZ too bad, as it’s very cheap, and you can assume that the experience isn’t going to be perfect when you’re buying a product made of DVD drive carcasses. The image and the selected settings are uploaded into the machine, and after that you can disconnect the computer and use it un-tethered by simply hitting the red button on the top of the machine to start the burn. You need to manually focus the laser onto the object you’re working on, as the focal point needs to be as tight as possible to get a good burn. This isn’t a huge deal with how common 5 V USB power adapters are (I’ve got a whole box of them), but seems pretty sloppy.Probably the biggest issue I found with the NEJE DK-8-KZ is the quality of the optics. Long story short, even if you aren’t using the NEJE DK-8-KZ connected to your computer, you need to have both ports powered. But even if you’ve got that connected, the board needs its own 5 V over the USB connection. ![]() When viewed under a microscope you can see that the laser isn’t completely removing the nail polish, which has hindered my attempts at etching so far.I haven’t given up yet. I had much better results using black nail polish, but still haven’t quite found the proper settings to get a clean burn all the way through. In the past we’ve shown somebody using a very similar device with pre-sensitized photoresist PCBs, so that should work well enough.But what if you just have some regular copper clad board? I tried spraying a scrap of board with black paint, but the laser doesn’t seem strong enough to ablate it away fully. It can easily cut through paper and 3M painter’s tape, which holds some interesting possibilities in terms of making stencils for painting and etching.If you’re reading Hackaday you probably want to know if you can use the NEJE DK-8-KZ to make PCBs. Word password remover for macIt isn’t perfect, but once you get used to the quirks the results speak for themselves.This thing isn’t nearly as good as other “cheap” lasers out there, and it doesn’t hold a candle to something like the K40. Turning a dirty hack like that into a product is worth at least a hat-tip, if not a few Jolly Wrenchers. (Sure, we would!) That’s not meant to knock it — honestly I’m impressed at what NEJE managed to do with what is essentially e-waste. Final ThoughtsThe NEJE DK-8-KZ is such an old hack that if somebody sent it into the tip line as their own project, we’d ask ourselves if we wanted to run yet another CD-sled CNC machine. I plan on keeping at this, and will post an update if I manage to get some good boards out of the NEJE DK-8-KZ. ![]() mihai.cuciuc liked VVD: an open source Real 3D Volumetric Display. mihai.cuciuc liked DESERT EYE: Military Surveillance Robot. mihai.cuciuc liked 3D Printable 2-axis MEMS Mirror.
