Epilog Zing 24 40Watt Laser Cutter Review

Epilog Zing 24 40Watt Laser Cutter Review

Online Exclusive Product Review: Epilog 40Watt Zing 24 Laser Cutter

By: Gerry Yarrish

Our RC hobby is a tool and workbench kind of activity. Once beyond the basics modelers begin to invest more time and effort with their models. Steadily a lifelong collection of tools develops. From specialty mini clamps, razor planes and X-Acto knives, to more serious power tools such as belt sanders, drill presses and metal lathes, the serious RC modeler constantly adds to his workshop and develops into skilled craftsman. It’s also common place for RC modelers to use CAD (computer Aided Design) programs to develop model airplane plans and have their parts produced with laser cutters. The hobby industry is rich with companies that offer laser-cutting services. Some cut to order while others produce complete or partial (flat) kits containing all the cut balsa and plywood parts with the customer supplying his own hardware and stick stock. Comparable with other high-end industrial-grade power-tools or shop equipment and priced about the same level as a complete turbine-engine-powered RC jet aircraft, Epilog Zing Series Laser cutters are within the reach of serious RC model builders.

Enter the Zing 24!

In business since 1988, “Epilog Laser” was the first manufacturer of small-format laser cutting and engraving systems. The company offers a variety of laser cutters for all levels of production with several different power levels. The company’s entry level line is the Epilog Zing Series featuring the Zing 16 (12×16 inch,) and the subject of this review, the 12×24-inch Zing 24. The Zing 16 is available with laser power from 30 to 40 watts while the Zing 24 comes with up to 60 watts. Our Zing 24 test unit is equipped with a 40watt laser.

So what is a laser cutter and how does it work?

The best way to describe how laser cutters function is to compare them to a desktop printer. You draw and design the part or parts you want with your own Windows–based PC drawing software. Epilog has designed the Zing 24 with open architecture software so it works with whatever program you already have. This includes CorelDRAW, Illustrator, PhotoShop, AutoCAD, or any other CAD program you might have. Then instead of sending the file to a printer or plotter to draw out the part, you hit the same “print” key and the file goes to the laser cutter. Load your material to be cut into the machine and hit the green “GO” key. It really is that simple. To produce a job file, all you have to do is set up your page within your graphic software, then import your drawing, make adjustments to the parts placement within the page, and print the job to the laser. At the Laser’s control panel there is a Job readout screen and when the job name appears, hit the “GO” button to start the project.

(Above) the Job Keypad is located on the upper right hand corner of the cabinet.

The actual laser is a CO2 gas laser, and uses a “Wave Guard” tube to produce a very fine (0.005 – 0.007-inch) beam of invisible, high intensity light. The laser tube itself is fixed within the frame of the laser cutter and the beam is directed to the work surface by two extremely high quality optical mirrors attached to an “X-Y” carriage driven by extremely fast stepping motors. One mirror is attached to the side of the carriage frame and always aligned 90 degrees to the laser. The frame moves (looking down on the work surface,) horizontally (Y-axis) relative to the drawing shown on your computer screen. The second mirror and a industrial grade lens, travels back and forth (left and right relative to your drawing,) on the traverse (X-axis) beam which rides on rails attached to the frame. Together this X-Y motion allows any size and shape object to be cut that will fit within the 12×24-inch dimensions of the work table surface.

The table itself also can be moved up and down (the Z-axis,) to properly focus the laser beam. This is required because of the various thicknesses of materials being cut. The max vertical travel of the table is seven inches, so very large objects can be loaded into the laser cutter. There is a front loading door in the laser’s cabinet for easy replacement of large items.

There is a focusing procedure that is very easy to do using a depth/feeler gauge that you use manually while moving the table with the laser’s Job panel located at the top corner of the cabinet.

Check out the Laser Beam Focusing Video here: 

(Above) View of the Work table. Notice the jackscrews for adjusting the vertical position in the corners.

The table itself is made from thick aluminum and rides up and down with four corner jackscrews. When doing vector cutting, you install the vector grid which raises your material up off the table to dramatically reduce backside burning. This grid is actually a box with the thin aluminum grid on the top. There are three vacuum holes that align with the ventilation holes in the back of the case. In use, the grid allows lose waste parts and debris to fall away from the material being cut. Using common sheets paper to seal off the open grids around your work piece help the vacuum hold thin parts flat onto the grid.

(Above) Here the Verctor Cutting Grid is in place on top of the Work Table Surface.

It is very important to always use the ventilation system and the air Assist feature to keep the laser’s optics clean and to remove debris produced by the laser beam cutting the material away. Of course, as you are actually cutting material with a high power laser beam, there’s always a chance of a fire, and you should always keep the work surface clean and never operate the laser cutter while it is unattended.

Laser Dashboard

The popup window that allows you to setup your laser and adjust the laser cutter for your job is called the Dashboard and it is here, that everything is made extremely user-friendly and fun. It is your interface where you control everything from speed and power settings, to job page size and the type of laser job be it engraving or cutting. For the RC modeler, most of your work will be done in vector format (line cutting). But you can also import an image to engrave onto a plaque or award and produce it by selecting the Raster format.

The “Dashboard” is part of the Driver program you install in the PC so it will recognize the Laser Cutter machine. Think of it as installing a new Printer. Just slide the CD into your computer and follow the prompts from the installation Wizard. Again, if you have the skills to run and use a graphic drawing program and install a new printer, you have all the knowhow necessary to run the Zing 24 or any other Epilog Laser cutting/engraving machine. Should you run into any difficulties setting up either the laser cutter or installing the driver program that comes with the unit, Epilog Laser’s customer and Tech support services are very helpful.

Getting Started

Ok here’s where the rubber meets the road. For the Zing 24 test unit we are reviewing, I used my Dell laptop PC running Windows 7. The Zing 24 is equipped with USB and Ethernet connections for printing as well as a serial connection for tech support. You can use Windows 2000, XP, Vista and Windows 7 with either the USB port or Ethernet ports. The USB connection is dependant on the settings within your computer, especially when using a laptop. The USB connection can go to sleep when your laptop goes into its screensaver mode, and depending on your settings may require a reboot before printing another job. However, these setting are easy to adjust and Epilog’s tech support can help you with the proper USB parameters. For my laptop I conneced to the laser cutter with the ethernet cross-over cable and assigned a new IP/address and Sub-net mask  to allow the computer and laser cutter to communicate.

(Above) Connection Ports


The basic setup of getting the Zing 24 to communicate with your PC is the important link you must first establish before anything can be done. Basically you set up the Zing 24 as if it were a new printer. With my initial attempt to set up everything I found that Epilog’s Tech Support people very knowledgeable and extremely responsive. Of course, the Epilog Owner’s manual is also very helpful and it provides step-by-step instructions for both USB and Ethernet connections making the laser-to-computer setup very easy. You do have to know how to use and adjust your own CAD program but from the Laser cutter to your PC connection you’ll up and running in minutes.

Speaking to the Zing 24

In the setup process, use the computer’s control panel and these local network adaptor settings as follows:

  • Use Internet Protocol Version 4 (TPC/IPv4)
  • IP/address:
  • Sub-net mask

Once this is done, your connection will work and the laser cutter is ready to receive jobs sent to it.

Speed & Power

The Speed settings determine the laser’s travel carriage speed in the Vector cutting mode. This is adjustable in 1% increments from 1 to 100%. The slower the travel speed is (laser dwell,) the deeper the cut. Most cutting applications require relatively slow speed settings, and the speed is heavily dependent on the hardness and the thickness of the material being cut. Slower speed settings will also produce better edge quality.

The Power setting determines the amount of laser energy used to cut the piece out and it is also adjustable from 1 to 100%. The higher the power setting is the deeper the cut. The amount of power needed to cut completely through a given material is also dependent on the properties of the material being cut. There is a Speed & Power recommendations section in the Zing 24 instruction manual but this is really only a basic guide. To properly set up any laser cutter you have to run test cuts to determine the best setting for the material you want to cut. An example of this would be the softness and hardness of the balsa select. If you set up the laser to cut relatively soft (contest grade) balsa, you may have to tweak the power (increase) or speed (decrease) for the parts to be cut cleanly through the first time. I ran a whole bunch of test batches for common RC hobby related material and came up with the following “Speed & Power” Settings Chart.

But Wait! There’s More!

Up until now, I’ve discussed Vector Laser Line Cutting, for producing parts needed to build an RC model airplane or Boat. The Zing 24 also has the capability to do extremely fine and detailed (photo quality) engraving on all sorts of materials besides balsa and plywood. The uses for this function are endless, from engraving your name in your radio case, or producing wood and acrylic trophies and plaques, to engraving glass and certain metals, the Zing 24 is amazingly easy to setup and use.

Engraving Functions

With the Dashboard interface, you can adjust the laser cutter to do cutting or engraving or both. When set to Vector, the laser cutter knows it should follow a line from one mathematical point to another within a CAD drawing program. To engrave an image, the “Raster” setting tells it to follow the image in a back and forth sweeping motion much like a dot-matrix printer. Every where there is a black or dark point in the line of resolution the laser fires, where there is white or no point, the laser shuts off.

(Above) Raster engraving on Oak plywood.

Again, the Dashboard allows you to adjust the power and speed of the engraving process as well as the resolution (fineness of the cut.)

The first “General” dashboard Screen allows the adjustment of the Resolution 100 to 1000DPI (dots per inch) as well as the options for job type (Raster, Vector, Combination), The piece dimensions (page size) both vertically and horizontally, Engrave direction, Image dithering, vector sorting, the frequency settings, and the speed and power settings of the laser for either vector or raster modes. The Center-Engrave option is here also and this is very useful for precisely placement (with the use of the Red Dot Pointer,) of your engraving image anywhere within the job window/page.

The second or “Advanced” settings page allows adjustment for Raster Type (Basic 3D or Stamp), language selection, and Firmware updating. You can also load and save various job configurations and have them show up in list form so you don’t have to constantly manually set the laser setting when you change from one job material to another; i.e. switching from one thickness of balsa or type of plywood to another etc.

The third driver page is for “Color Mapping” which is the process of assigning various speeds and power settings to various colors you can use in your job drawings. It uses an RGB (Red, Green Blue) color management so you can produce various custom colors should you want to. The default colors available to you are: red, green, blue, yellow, purple and cyan. All of these colors are the same default colors for my CAD program so I did not create any custom colors and add them the mapping menu.

To use Color Mapping, first you click the Color Mapping option box. Then you highlight the color you want to adjust, and use the slider controls for Speed, Power, Frequency and Focus. You can also assign the Raster or Vector (or Both) function to the color. When you are done, you hit the transfer arrow to load the settings to the color you’ve selected. For all of my jobs, I used green for vector cut, cyan for vector engrave, and blue for raster engrave using the power and speed settings in my chart.

Once all these settings are input you are ready to go. You place your image/job anywhere within the page in your graphics program and the laser cuts and/or engraves in exactly that place within the dimensions of the cutting table surface. And that’s when your fun part begins.

Bottom Line

The Zing 24 laser cutter from Epilog is perhaps the most amazing tool you’ll ever use. It is high quality, industrial grade, super easy to setup and extremely user-friendly. Whether you are looking for a great addition to your workshop or you’re on the verge of starting your own kit-cutting company, this quality, industrial-grade, reasonably-priced laser cutter is now well within you grasp. If I were to start a new kit cutting business, I think it would be a smart move to build it around an Epilog Laser!

  1. Gerry,

    What accessories or options did you get with the laser? I’m thinking of sprining for one this fall.



    1. Hi James. I think you will find the Zing 24 a very impressive machine. I tested the unit over a 4 month period and it was equipped with the honeycomb vac table to hold thin material flat down, and the vacuum/filter cabinet (optional) with hand-held remote on/off control. As I mentioned in the online review you can run the Zing with a separate shop vac/air filtration system if your shop already has one simply by connecting the cutter with a 4 inch flex hose to your system. Everything else is ready to run. The only issues I had with the whole setup procedure was with my laptop. You have to setup the proper ports so your cutter and computer can communicate with each other. Epilog customer and tech support are awesome to work with
      good luck!

  2. Dearest Mommy,

    I know what I want for Christmas this year!

  3. I’m not sure where you are getting your info, but good topic. I needs to spend some time learning more or understanding more. Thanks for magnificent info I was looking for this info for my mission.

    1. Actually, I got all this information by running the Zing 24 laser-cutter in my workshop for several months. All the photos I took while running the unit. I made several (dozens) of test cuts using various materials. Speed of cut and the power setting for the laser beam greatly affect the quality of the finished cut. A great tool everyone serious about RC would love to have in their shop.

  4. Hello great artical. Im coureous have you tried the Zing 24 out on leather?

    1. Lewis, I use a zing 24 30 watt machine and it works great on leather, check out some of the work I have done with the laser on my FaceBook page.

  5. Hi I’m new in this game and at this stage and learning a lot.My machine is a Perfect Laser 50watt.To engrave is not so difficult but to cut.What I’m looking for is Patterns or design templates that I can cut or websites where the stuff is sold from
    Hope that you can help me!Thanks

    South Africa

    1. Hi Johan. thanks for your comments. That’s the catch… Laser Cutters relie on CAD drawings for the most part to produce parts. They go hand in hand. I do not know of any sources for parts drawings. You might want to try the http://www.radiocontrolzone.com forum and register there and ask for comments there. Maybe someone can help out. Cheers,

  6. Does anyone know the price for this system and I’m very interested in engraving wood gun stocks and wine glasses. Can the Zing 24 do this? Last question, is size the ONLY difference between both zing models?

    Thanks for your help!

    1. The zing 16 x 12 cannot be fitted with the rotary additional attachment so you’d need the zing 24 to do any cylindrical engraving or cutting the next model up the helix mini has servo motors rather than stepper motors. Gives them higher travel speeds and a flatter torque curve for better results on curves. Going from say 18in/s to 40in/s good for production but not really needed for hobby work

  7. hi Gerry,

    Can u send me design of each part of the airplane?



  8. Depending on what type of file the laser uses ,DXF OR TRUE CAD FILES. There are many pieces of software out there that will convert a scanned jpg or bmp to a dxf to import to your cad system or directly to the machine. I have scanned blue prints converted them and scaled to the size that I need. One such software is Vextractor, it is pretty easy to use.

  9. I am tahir maute of marawi city, Mindanao (Philippines), i have a small business, making most on personalizing items or customizing items. i would like to have laser cutter or that can engrave image or text on wood or acrylic surface. asking favor how can i avail that machine by installment basis, or any procedure? i don’t have much or enough money to cash or fully paid that machine.

  10. Gerry, you’re awesome!

    Thank you so much for sharing this information. I’ve been looking for a way to create tiny peices for my greeting cards, without Xacto-ing 100s of them.

    I don’t want to assume, but this will laser cut through inches of paper sheets.

    Thanks again, your insights are helpful and delivery of detail is very concise. Much appreciated!


  11. I have access to a Zing 24 50W laser cutter (i step up fro the one reviewed here), and by following the power cut settings above, I have not been able to cut through a lousy piece of 3/32″ hobby plywood. thelaser just seems to go 1/4 or 1/2 depth of the wood and never all the way through.

    I’ve tried the 30/30 setting, 40/30, 30/40, 10/100, 100/10, 50/50, 70/20, 20/70 and tons more and have yet to actually have the laser cut through the wood in one pass!! the Frequency I am using is 500, vector only.

    Anyone have a suggestion as to what settings to use for 3/32 and 1/16 plywood?

  12. Gerry, thanks for the well done review.

    For G$, what frequency did you find worked best?


  13. quite interesting im using zing 24 hw cn i get various templates of different planes to be assembled using balsa wood

  14. Would this be a good laser for engraving on 2 to 4 foot long boards that are 4 inches to 12 inches wide. Would there be a better alternative for that type work. Talking about engraving letters on wood mainly.
