3000mW laser class 4 engraving machine Laser Engraver Printer Mini desktop laser engraver machine DIY Logo laser engraver 7.5X7.5CM (3000mW)

EDIT: Mine broke after about 10 days. Did one job, unplugged, next time plugged it in and.... nothing. No power, no response. I'm exchanging, and will hopefully have better luck with the next one. Leaving my 4-star review in place until/unless the next one breaks. In the meantime, all of the below comments apply, at least for a working machine.For those reading in the future: This was written July 2019, so comments on price vs. performance may be obsolete by newer machines.This is a decent machine for beginners with just a little bit of patience. It produces crisp, detailed engraving on the supported materials I have tried so far (card stock, paper, wood, leather).Four stars because the software included is about as basic as it gets, meaning you need to be comfortable with at least a little image editing. Also because it does not support vector image files (like svg) and is not GRBL compatible. This means it can't just trace a circle or image, it has to scan through every line of it, making it take significantly longer to engrave basic images. However support for vector graphics probably wouldn't save much time on anything details.A few tips:1) You must properly focus the laser to the smallest possible point. The documentation can be confusing here, it's in poorly translated English, and in one place says the point should be "maximum" which is absolutely wrong.2) You must experiment with the "depth" and "power" settings for a given material. This is literally burning the material to produce an image, so if you just blast the thing at the highest power and highest depth then it's going to burn too much and make the image look bad, blurry, etc. because too much of the surrounding material gets burned. As an example, I tested with vegetable-tanned leather. At 90% power and 50% depth it produced and "okay" image. Good, but not great. However if I turn it down to 60% power and 20% depth, I get a fantastically crisp and clear result. However they are more of a dark brown than black. On power and depth levels that that produce a dark black, they tend to cut deep enough that there's not only a lot of char and less crispness, but the leather tends to split if it's flexed a bit afterwards.3) Image editing: You must be willing to get your hands a bit dirty here. You can't just open a picture and expect to get the desired results. Photos will likely be too big, and you need to scale them down smaller. If you have no image editing program, you can get GIMP for free, but it has a learning curve. On windows you will already have mspaint though, just search for it. It's basic, but you can open common image formats, select the part of the image you want, crop it, and use the "resize" option. Near as I can tell, the software for the engraver is working at around 600 dpi, meaning that an image that is 600x600 pixels will translate into roughly a 1 inch x 1 inch engraving. With an engraving area of about 3x3, that means the largest image you can engrave is about 1800x1800 pixels.4) Software it comes with: My USB stick had two versions: 1.0 and 1.5. I use 1.5 because it seems to over more control over power and depth. 1.0 has only depth, and I think something that corresponds to "contrast", which I don't quite understand. There should really only be two variables: Power of the laser, and depth which should control how fast the laser moves over an area. However I can't get the built in text feature to work with 1.5, meaning I need to write text in another program and convert it to an image.5) It will take a while to do its work. An image I printed that was about 1.25" x 3" took about half an hour. Lower power or depth settings do help with this a little. For example something that took about an hour on full power, full depth, took about half an hour on 65 power, 30 depth.6) Safety: don't rely on the single front cover alone. This thing shoots very intents bursts of light out of its sides and back that probably aren't great for you. And you should NEVER look directly at the point of the beam on the material as it engraves. It is absolutely a risk for eye damage. Lasers like this throw off more harmful bits of light than what can just be seen by the naked eye. Whenever I see youtube videos of these things in action I'm hoping the person is closing their eyes as they video it (though they probably are not)7) Also safety: remember you're burning things. It's not a good idea to leave these machines unattended. You should also probably use it on a surface that isn't likely to catch fire. Get a 1 foot x 1 foot tile from home depot or something.8) Longevity: I've only used mine for about 2 hours, but I know a bit about these things. This machine it both cheap in price and likely in quality for its parts. It really is made for low-use / minimal hobby usage. If you run it at maximum settings for a while, or use it continuously for hours a day, it probably will not last. If you need something that can do a bit heavier of a duty cycle, look into the laser engravers on amazon that around 7000mw. You can run these much longer at 25% power and get similar results. Though if you are running a business that uses it or something like that that needs constant regular use, this class of machine may not be suitable for you. If you want something a bit DIY but a very good step up in quality and capabilities, get a 500x500 Xcarve and a Jtech laser add on.9) Other options with higher power: This is a laser diode machine. From what I know, they're currently limited to around 7 watts/7000mw. You can find machines that powerful on amazon. But you will also see some that are stated to be 15watts/15000mw. This is not quite the case. As I understand it, these are 7watt lasers that are put into overdrive to get the more powerful output, which means they're much more likely to burn out quickly.

Disclaimer: All I got this unit for was to etch black and white clip art and lettering onto wood, and that is all that I have tested. With a little twiddling and trial-and-error you can get 5-star results for that. 2 stars for the manual. I can forgive the fact that it was obviously written by someone whose 1st language I NOT English. And it is pretty slim on content. But it does have one glaring mistake - don't focus the laser dot to maximum size like it says, go for minimum. 3 stars for the app that runs the engraver from the PC. Another disclaimer: I write apps like this for a living, so I have very high standards in this area. Some things the app could do better: 1) it could remember the settings I used the last time I used it, 2) it could automatically connect to the engraver, 3) I can't tell whether the fan is on or off by looking at the fan on/off button, 4) It does crash occasionally. Negative: The manual warns that the laser can overheat and recommends that you don't run it continuously for more than 30 minutes. But etching the full 3"X3" area can take well over an hour. So if I was really worried about this I would have to watch the clock and pause an etching that is in progress after half an hour, then start it again. And the manual gives no guidance as to how long to cool off. This SHOULD be handled automatically by the app. Negative: There are two slider controls: laser power and etching depth. The manual gives no guidance as to how pick a good pair of values for these two settings. Trial and error your only option. I also suspect that "etching depth" is really how long the laser stays on when burning each pixel, but again, the manual doesn't say that. Maybe a negative for you: the manual apologizes for the lack of graphical editing controls in the app. All the app can do is rotate the image in 90 degree steps and shift a small image around in the bigger etching area (enlarge and shrink would have been nice). No big deal for me, I use full-blown Photoshop for graphics editing, but Paint (on a Windows PC) would be an adequate alternative for doing things like enlarging or reducing an image. Tip #1: I was having trouble getting the engraver and Photoshop to agree on the dimensions of an image stored in PNG format (the only format I have tried to use). Use a resolution of 200 pixels/cm and they will match up. Tip #2: When focusing the laser, use the manual controls on the top of the engraver to bring it out the front edge of the machine. That makes it a little easier to get your fingers around the lens or just use a pliers. Final summary: I am quite satisfied with the results I can achieve. At this price point, the performance outweighs the negatives I have listed.

Fonctionne très bien pour les petits articles 3x3 pouces max. Je l'utile à tous les jours pour m'amuser sur du bois et le cuir. Je vais m'en commande une plus grosse pour des projets plus grands. Facile d'utilisation. Il ne faut pas être pressé 1 heure pour des photo, mais le rendu est excellent.

I just wish there could more designs or instruction

Nice details, but slow. Because of the only 2 axis.It "print" line by line. Very good, but very slow.

Returned didn’t work

Can't find the app to install to use this laser engraver
