Genmitsu L8 Laser Engraver, 40W (40000mW) Power Output Laser Cutter, 40000mm/min All-in-one Laser Engraving Machine with Acrylic Enclosur, Air Assist Pump, Honeycomb, Camera, Safety Class 1

I've had 3 other lasers before this one and let me tell you, it's unfair if you get this as your first laser. You should have to assemble a janky cheap one as sort of a rite of passage before you upgrade to something this ridiculously ready. Assembly is basically done for you. Just hook up a couple cords and put the laser on the mount and it's ready to go. It took me a little while to get the driver downloaded but that was on me. It's already included on the tf card that comes in the machine. Once I got that figured out this machine is a sinch to use. Look at this video. This is like 5 minutes into messing with it and I got a super clean cut through the plywood they include. You'll also noticed how fast the 40w can make that clean cut. I'm pumped. It's going to be so fun to use this. The enclosure is fantastic, funnel all your smoke out a window and don't worry about onlookers hurting their eyes. Sure the fan could use a little more oomph but it does what it's meant to. Just give it a few seconds when you're done to clear out the smoke or buy an upgraded one if you want. The air pump works great. It's pretty quiet and it's connected to the machine so you can use the dial on front for more or less airflow and you don't need an extra outlet. Last but not least, check out how cool this think looks! Its guaranteed to make your workshop look higher tech and futuristic! For all the stuff that comes included, this is an excellent value in my opinion. Definitely fast and accurate enough for production for a small business. I've had other genmitsu products like CNCs and they've been excellent so I bet this laser will last a long time without issues too. I'll update the review if I run into any problems. I was just so excited about how cool it is I had to leave a review and let everyone know right away.

Excellent machine, comes almost fully assembled and is ready to use in minutes. I’ve been cutting 1/8” plywood for a few hours a day for the last month and have had no issues with the laser getting weaker or not cutting as well. Very easy to use with light burn, looks sleek on the workbench, and is able to go significantly faster than other lasers I have used. Everything is assembled well and seems strong and sturdy besides one of the plastic cable hood downs that broke, but it didn’t seem necessary to have in the first place. Update 1/16/26: Laser is still going strong. I’ve cut hundreds of 12x12 sheets of plywood and a bunch of black acrylic. I also use it to make pattern outlines on leather and cut gasket material. I haven’t ran into anything it can’t do that other diode lasers can. Diode lasers aren’t meant for metal, but it does work okay on engraving some with a marking paint. I clean the entire laser and the head regularly. I couldn’t figure out how much should take apart to clean the fans so I contacted support. Within two days I had a full off sent to me on how to clean everything. I then had an issue with one of the screws stripping when going to clean the laser module fans. I contacted support and they responded immediately with the proper screw size and where to find them. Excellent machine, excellent customer support. What I’ve come to expect from sainsmart! The alignment and camera are spot on, I never expected to use the camera but it makes life so much easier when lining up pieces of leather. With lightburn it homes itself when the program opens and maintains its positioning unless you bump it. The belts have stayed tight and I haven’t even had to replace the lens yet. All in all I am very satisfied with the purchase and have already gotten my moneys worth out of it.

Not very easy to set up and use this thing.

Terrible product, nonexistent support. Does not live up to claims made by manufacturer and their material sheet. Recommends engraving wood at 36000 and 100%, but barely makes a light mark on balsa wood. More like 25000 at 100%, a very large discrepancy. Does not cut steel or engrave it. The tolerances on this are embarrassing, the lid does not sit flush, laser leaks out underneath a rather large gap between it and the bottom frame. The camera is impossible to get to stay calibrated, as the cheap hinges, non flush lid, and poor quality lead to a constant shifting of the camera angle. It does not cut accurately, frequently being 2-3cm off from the light burn position. It also does not match the scale given. Example edge to edge or a gap from the edge, it either comes out too small or too large consistently. Sometimes it cuts random non existent lines. I have spent about 20 hours trying to get this to work, and have sent emails to support with no reply. There is no phone number. Go somewhere else.

The Genmitsu L8 has worked well so far. I haven't really tested it's limits yet. It is much faster than a 10 watt I own. The camera was suppose to come calibrated but I found that it had to be re-calibrated as it was off by almost an inch. Once calibrated it has worked pretty well, getting it calibrated was a chore. It cuts nice but it is not as intuitive as my other laser, it has to be focused by hand. The lever that tightens the laser to the frame is extremely hard to loosen once tightened-I had to use a screwdriver to wedge it loose to adjust the focus. There are 3 fixed focuses. I made a printout for the focus parameters and taped it to the front of the machine so that I don't have to pull out the manual every time I need to adjust. The machine was packaged nicely-no moving parts during shipping. This machine does not have a bottom. It comes with a honeycomb that slides into place by lifting a corner of the frame and pushing it under, it does slide nicely into place but it will sit directly on the counter/table top but, it is not attached to the machine. The frame does have legs that tuck away nicely when not in use, which makes for a nice smooth look. While the surround is nice, prevents too much smoke in the room and helps with eye protection, I have 2 kittens who like to jump/sit on anything that does not move and their weight is enough to bend the top while even one of them is on it. I have had to rig a cover that keeps them from sitting directly on the machine while also protecting the camera surround that juts out of the top. The surround is framed acrylic, the top is not framed, it is a single piece of 3mm hinged acrylic. The connections are on the front of the machine, the fan on the back which requires more counter space than I had originally planned for. I prefer direct connection, which means that the machine requires 2 USB ports to use the machine and the camera at the same time via USB. I haven't tried the wifi connectivity. The L8 does not have proprietary software and requires Lightburn to use the camera. It was an added expense-(though most laser users have this program, I did not because my previous laser came with free software). I have not had to contact support so cannot write about that. It is difficult to find information about this particular machine. There are some "I got this laser for free to try/review" and manufacturer videos but not much else. I purchased this particular model while it was discounted and had a coupon which made it significantly less expensive than other 40 watt enclosed lasers, with a camera, currently on the market. My father owns a Genmitsu Prover (with laser attachment) and he has had it for several years, so I know the brand makes quality frames. I haven't been able to determine if a beginner would find this machine overwhelming or not. It comes already built which is a positive (I had a laser that had to be built and it was a chore as well) it has a surround, if you can use vector software (LaserGRBL or Lightburn) then it is just a matter of connecting and starting. Any laser will require a learning curve and a certain amount of waste material for testing.

I bought this 40w laser to replace my couple year old 10w laser and wow, what a difference in quality! While my first laser was great for learning on and such, it doesn't hold a candle to this behemoth. With the enclosure, not having to wear those glasses anymore is fantastic. The camera can use some adjustments, but is still better for lining stuff up than no camera. It definitely speeds up the process of setting up. Having air assist is a must! It makes my projects come out so much cleaner. Performance wise, it's fast. With four times the laser as my old one, it breezes through stuff that used to take me much longer, or not able to even handle at all. So far, I've cut and engraved wood, leather, and acrylic all with great success. The only issue I've had with it is that on a rare occasion, the cable that attaches to the laser can get in the way of the wheel and cause it to not move. I haven't looked fully into yet, but I'd assume it's just about moving it slightly so it can't get that close to the wheel. I should also not, that it only happens you are trying to laser the very top center edge of the bed and again rarely happens even then. Overall, I would say price wise, is the best bang for your buck when looking at other comparable models.

An awesome machine. Solid built, packaged so well that it is difficult to unpack. Includes everything necessary to get up and running with the exception of a computer. Quiet air pump, cables, and several sample materials included. The only downside is the acrylic enclosure is on the thin side and requires a little care to avoid damage. I had a minor issue with the built in camera connection and contacted support. They were quick to respond and the issue (my error) was resolved. I have engraved wood slices and granite style coasters using Lightburn software. The camera makes positioning the item to be engraved a simple task. A real pleasure to use and as a previous CO2 laser user this diode laser is a far superior design, more accurate, and easier to operate.

I love this laser engraver. I have been using it for several months and it is very versitile.

My second machine. I had the 5w and then upgraded to the 10w. I'm still using this machine and recently got the L8 40w. I am not disappointed so far. I can't wait to see what I can do with this new machine.

Muy buen equipo, definitivamente recomendable. Supera las expectativas. Gran variedad de opciones para corte y grabado láser en los distintos materiales. Sólo hay que documentarse ya que algunos materiales requieren trucos para que funcionen. El hecho de que viene ya ensamblado y listo para usarse es un plus.

Really impressed with this engraver/cutter. I had a K 40 CO2 laser before and the simplicity of use with this. The fact that it works with LightBurn has a camera doesn’t require water cooling and as you can see in my photo will cut through 1 inch pine in a single pass Has greatly impressed me. I do recommend this product.

I've used and built a number of laser cutters. I returned this machine. Laser spot is poorly focused, over 0.2 mm. This is much larger than advertised (0.07 x 0.13), resulting in blurry engraving and inaccurate, smoky cuts. It does not operate like a 40W laser should. Material cut instructions from manufacturer’s website are inaccurate and do not work; machine does not cut or engrave cleanly. They tell you to use the 18mm focus for cutting thin material and it produces horrible smoke and bad cuts. Camera cannot be properly calibrated due to flimsy case design. Materials cannot be accurately and repeatably cut. The thin plastic top bounces around every time you open it, and the camera is in the middle of this. This is a silly design choice and the camera doesn't even show the whole work area. Laser focusing mechanism is poorly designed, difficult to use, moves the material, and is not repeatable. Unacceptable for professional use. It's a bolt on a rail that doesn't slide easily. The laser head is very heavy and if you just let it drop onto the material it will be too low and you can't move the head at all. Cheaper machines have autofocus, why doesn't this one? Honeycomb grid is poorly designed with no air gap, leading to smoke buildup on back of material. This is a very bad design choice, the metal plate under the honeycomb is right against it; you can't clean it and air can't circulate. It's almost as bad as not using a honeycomb at all. Protective film difficult to remove from bent edges, leaving machine looking unprofessional. A nitpick but annoying. Laser head can bump into internal brackets, causing loud noises and possible damage. The 40W head is so large you have to be careful with its vertical position or it will clonk into things. Air pump sensor poorly calibrated, does not report air flow correctly. This just didn't seem to work at all. Genmitsu may have thoughtful CNC machines, but this laser cutter is poorly designed and half considered.

Machine was damaged as i started it laser keeps going out of bounds and make very loud belt skipping noise. Even almost caught fire as it kept firing non stop. Caused a lot of smoke and residue
