L8 Laser Engraver, 20W Laser Cutter Built-in Acrylic Enclosure with Vent, Air Assist Pump, Honeycomb, Camera, All-in-one Plug and Play Laser Engraving Machine, Laser Safety Class 1

I bought this Genmitsu L8 in July and have used it pretty extensively since then - mostly for laser cutting wood but a bit of engraving on wood and metal. I found it very easy to set up and get started although the instructions are a bit simplistic and I still could use a better description of the focus and power levels for cutting and engraving various materials. Even after using it for months and it would have been helpful to have a better explanation of the line interval/resolution but I figured it out by watching YouTube videos for other laser machines.I installed Lightburn instead of the stock software and that has worked very well. I find that this 20W laser is very capable and it meets the specifications and cuts cleanly and quickly through 5mm plywood and does a great job engraving aluminum, plastic and steel - I have had a bit less success with wood which has been coming out less crisp than I’d like but maybe I need to spend more money for better wood surfaces and based on the excellent results from metal and plastic, I’m thinking my wood engraving issues are either cheap wood or user error.Overall I’m very pleased with my purchase and I use it constantly and it meets the specifications claimed by the manufacturer.EDIT: I found the power, speed, and line interval settings for various materials and thicknesses on the Sainsmart/Genmitsu website after I wrote the review.

The L8 came packaged very well and everything was secured inside. There is not really any assembly except for the laser. There was not specific instructions on the installation of the laser, but it is straight forward. First make sure the locking mechanism is backed out. The handle is spring loaded so when you pull it out you can move the handle without turning the tightening screw. The v guide it travels on has a clearance on the bottom. By placing the laser as high as it will go the laser is will go into the channel. You have to push a little on the clearance side to seat it. After that it was good to go and the directions outlined the next steps. When the weather warms up a little more I will put this through its paces. I did not get the exhaust purifier so I do not want to try any heavy cutting unless I can be in a well ventilated area.In general the construction is excellent and should provide good cutting and engraving. I was using a 3080 CNC Genmitsu for laser engraving, but the power of the laser and focusing made it difficult to get setup right. I am hoping this machine will replace that equipment and I will put it back to CNC use.I am also looking forward to trying the camera out on lightburn. The function would save a lot of time if the consistency is there.I was also surprised by safety functions. The key switch and e-stop are the more general safety options. The ones I really appreciate are the interlocked enclosure, flame detection, and tilt detection. These features really help instill confidence that the machine will generate a safe experience.In all I think the L8 is good value for what you get. Also the Sainsmart support has been top notch for me and having purchased cnc, 3d printers, and lasers from them, I am sure they will provide excellent support on the L8.Once I get everything dialed in I will try to share more pictures.

I purchased this laser cutter based on it's features. I liked that it had a complete enclosure and safety features. Unfortunately, there doesn't seem to be much in the way of Quality control.When I opened the box and removed the unit I noticed a loose screw in the box, not good...I then attempted to access the instructions located on the USB drive. The drive couldn't be read. I tried it on three different computers and none of them would recognize the drive.I contacted the vendor and explained the issues. They did respond quickly with a link to the software that I could download and they asked for a photo of the screw. I sent it them A few days later they told me the screw was an adjustment screw for the ways and asked me to confirm one was missing, which I did.I did ask how they could send me a unit that wasn't properly adjusted but, I haven't heard back regrading that question.I received the laser cutter on June 11th and haven't even tried it because I'm concerned that it wasn't properly tested at the factory. I'm hoping that SainSmart gets back to me and addresses my concerns soon. Otherwise, I'll have to return the unit.

i like it, but the user manual doesn't have any instruccions

This is my secondGenmitsu product. My 1st was a Genmitsu 3018-PROVer. I had questions regarding upgrading my 3018 with a Y axis upgrade kit. Within a couple of days I got my answers and ordered the parts to do the upgrade.So when it was time to upgrade my K40 CO2 laser. I knew I wanted an enclosed laser and I wasn't all the interested in fiddling with the constant alignment and replacement of cheap mirrors. It was going to be a solid state laser.Prior to purchase I had a question regarding Lightburn software which was answered quickly by theGenmitsu Techs, and when my L8 package arrived I noticed some shipping damage on the box, So before I even opened the box I wrote and asked if I should return it, or open it. I was told it would be OK to open it, if there was any damage they would make it right. It turned out the packaging was done very well and the laser was fine. I was able to install Lightburn on my laptop and complete the camera alignment. And do a couple of small test cuts. My next investment is going to be a smoke purifier, probably the Genmitsu MD13.I am in no way connected to Genmitsu and I have paid for these products out of my pocket. To be 100% honest I would be thrilled to have manufacturers throw products to me to review. But I cant see that happening as I have no online presence other than Amazon reviews
