Longer Ray5 Laser Engraver 12

REVIEW – For several years I have been using 3D printers to make and model several items and have enjoyed doing so, especially for decorative items. Machines like 3D printers fascinate me and I find that they allow me to bring my imagination to reality. I am so excited to now get the chance to test and review a laser engraver for the very first time. Let’s see how the LONGER RAY5 Laser Engraver works!!

What is it?

The Longer Ray5 laser engraver features a built-in 3.5” touch screen, a TF Card Slot, and built-in WiFi. In addition, it has a built-in controller, and no computer is required to be continuously connected to the laser engraver. The Ray5 can be used for engraving or cutting.

Design and features


  • Touch Screen & Offline Carving: LONGER RAY5 laser engraver has a built-in 3.5” touch screen with a friendly user interface. This allows us to cut multiple pieces of plywood or images to be engraved without tying up your computer to run it. The Longer Ray5 has a built-in controller and no computer is required to connect the laser engraver all the time. Save your file to a TF card, and use it to run the Ray5 for engraving or cutting.
  • Ultrafine Laser Point & Powerful Laser Module: This laser engraver comes with the latest FAC laser technology for compressed laser points, the size of the point is 0.08*0.08mm; The smaller size of the point, the more focused the energy. This allows the engraving or cutting to be much stronger. The output power of the laser module reaches 5-5.5W.
  • 32-Bit Chipset & WIFI Connection: RAY5 is built with an ESP32 chipset and includes a WIFI connection for the engraver to the router. This 32-bit chipset is running at 240MHz. That means it is faster and more powerful than comparably equipped machines with 8-bit chipsets. As a bonus, the RAY5 supports WIFI connections through the web page or App to control engraving or cutting.
  • Safety Protection: LONGER RAY5 is designed with move protection and thermal protection functions. If the machine is moved while in use, Move protection will initiate auto-shutdown for personal safety. Thermal protection initiates an auto-shutdown if it detects a flame or the engraving area overheats.
  • Compatible with Windows/MAC/Linux System: RAY5 is compatible with free engraving software LaserGRBL and paid LightBurn software. It supports import with BMP, JPG, PNG, DXF, AI, SVG, etc file format.
  • Power Button & Eye Protection: The engraver comes with a power switch to turn the power on or off. The laser module has an acrylic cover. This shields the laser light to help protect the eyes. You will want to wear eye protection for laser scatter as well.

The Longer Ray5 Laser Engraver is made of what feels like aluminum. It is lightweight but strong. Assembly is required, but it is easy. The laser has a shield on it and shades are included. Also included are a USB micro SD card and adapted. a USB cable and the Allen wrenches to tighten the screws.

The first step was to assemble the engraver. It is quite easy as long as you take your time. The instructions in the manual are not very good, but there is also an instructional video on the included micro SD card. However, I did not need the video. The following are some photos of my process:

There is additional software on the memory card including manuals, firmware, an instructional assembly video, and 2 design applications. There is a metal cylindrical tool that is used to set the height of the laser above the material that you want to engrave:

Once the height is set, it is time to insert the micro SD card and get to engraving. A USB cable is included if you want to use an external hard drive or a direct PC connection. In the photos below I have also included some of the screens on the touch control screen:

Watching the Longer Ray5 Laser Engraver is very enjoyable and much like when I watch my 3D printers print. However, this device causes quite a bit of smoke and of course the smell of the material you are engraving. The included shades are necessary if you want to look at the laser to see what it is doing. I would recommend using this outdoors or at least in a workshop. Also, I did not test the cutting capability because I currently do not have a proper surface to place underneath the material I cut. If an enclosure is included along with some material to restrict the depth of the laser, the device would be even better. The way the engraver works you can select how many passes you want it to make when carving, and with each pass, it cuts deeper. I have to assume that it would take some hours to cut through the 1-inch think board that I was using to test. overall, this is still a really nice engraver, and the large printing area makes it very versatile.

What I Like

  • The build quality
  • The relative ease of assembly
  • The site of the printing area
  • That software to design and print is included
  • The quality and speed of printing

What I’d change

  • There should be an enclosure for the smoke/fumes that the printing causes and some protective plate/material to place under the material that is being engraved

Final thoughts

This is the first time that I am testing a laser engraver, and I must say that I really like the Longer Ray5 Laser Engraver for the quality, relatively quiet operation, and the quality of the engraving it produces. Since it is not enclosed, in the future I will have to use it outdoors, maybe in my garage. It gives off quite a bit of smoke while engraving, and then there is also the smell like the smell of burning wood if that is the material you are engraving. I tested it indoors and the fumes were the unpleasant part. However, the experience was great for me, and this engraver is very capable, especially because of the larger build area. I give it a well done!!

  2. I have recently bought this and although the build was fairly easy, after putting the sides on back to front. However the “ instructions” are just to put it together. There is no information on connecting to the WIFI nor how to upload your own patterns beside the 3 enclosed. Also even though I framed each practice piece before engraving the wood it still burnt was off centre. Considering it was advertised as EASY to build and use there is no user manual unless you plug in the USB on the PC or laptop. My PC is quite a distance from the table we are using for the engraver. A printed manual would have been better. There was nothing to tell us WHAT SOFTWARE or App to download, how to make more than 3 patterns & especially HOW we get the files from the PC to the engraver to engrave.
    I am looking forward to trawling through miles & miles of questions, answers, posts on the internet where the information is sketchy at best when a printed manual would be so much easier. As for the trees to make paper is concerned a lot more is used trail & error to get the pattern correct.
    All aboard the longer Ray 5 5w manual train in circles!!!

  3. I received this engraver for my birthday and I am ready to pack it up and send it back. No instructions, no manual. You can’t find any instructions on line to help with issues. I have no clue what all these symbols and garbage mean so I have no idea how to fix the issues I am having. One minute it will engrave fine the next it stops and no way to get it started again.
