 I've had this laser machine for almost 3 months now, and I absolutely love it! My girlfriend and I use it almost every other day making gifts for family and friends. It has been a great way to hone our graphic design skills as we constantly explore the limits of this machine. The machine works well straight out of the box, but after two months of research, experimentation, and upgrades, I have greatly increased the ability, performance, and quality of prints. I've replaced the lens with a G2 lens (which is phenomenal for cutting through material), I've added air assist (which also greatly increased the beam's cutting power), I've upgraded the original 5W laser module with FoxAlien's 15W module (which allows me to engrave must faster), I've modified the GRBL configuration in order to increase the max feedrate beyond 3000mm/min (currently, I'm set at a 10,000mm/min jog rate, and I engrave at 6000mm/min, 0.1mm line spacing, 100% laser power), I've put together an enclosure for the machine with a 12"x24" orange laser safety acrylic window in front (tremendously increased safety and comfort while near the machine), I've got an exhaust fan sucking the fumes out the window (keeps the smoke out!)

With the G2 lens and air assist, I've cut 6mm birch plywood and 1/4"(6.8mm) solid Poplar wood with the 5W module (about 7 passes at 200mm/min full power). I've yet to try the max thickness with the 15W module, but I do all my cuts at 600mm/min with it and it performs the same as the 5W module at 200mm/min. I cut 3mm plywood at 3 passes, 600mm/min, S1000 using the 15W laser.

Pros:
*Very economical price for the quality of product received. (1 year warranty)
*The included software works very well and is easy to learn. (LaserGRBL)
*5W laser module is very powerful, the 15W is a beast!
*Able to increase max feedrate beyond factory settings
*Great wire management using wire tracks
*GRBL controller board is very nice, has ports to add extra features (limit switches, pause/resume buttons)
*Customer service is amazing! I've bombarded them with questions all along my lasering journey.
*Their Facebook CNC group is very helpful and a growing community of creators!

Cons:
*There is a learning curve, but you should know what you're getting yourself into. Even though it works right out of the box, you will need to learn and do a few things before it'll perform how you want it. You'll have to learn how to ideally focus your laser beam. You'll have to learn about different lens types (G2, G7, G8, etc). You will need to add air assist to keep your wood and the lens clean. Lens cleaning is routine maintenance for any laser machine. The images do not create themselves, you will need to know how to do image editing and how to create your own files for the machine (or you can purchase designs). There's an insane amount of tutorials for many different free programs which will do everything you need to do on this machine.

The LE-4040 is my first CNC machine that I've owned and operated. It has facilitated so much learning for me the last few months! It is perhaps one of the funnest tools I've purchased. A few weeks after I got my first one, I bought another one when they went on sale. I'm using the second one to build a large scale version of this machine using longer 1500mm long 2040 v-rails and longer belts. It was a great deal to get all the parts to build it, plus I really am surprised at the capability of this GRBL controller.

A few important pointers:
1. Make sure you set the machine into Laser Mode ($32=1)
2. Use the M4 command instead of the M3 command for engraving
3. Invest the few bucks to get a G2 or G8 lens (G2 especially if you want to be serious about cutting)
4. Air assist is something you should immediately pursue
5. Build an enclosure with exhaust fan and duct, or put near window with a fan (temporarily)

Designed to Work With Your Laser

LightBurn talks directly to your laser, without the use of additional software.

We currently support most Ruida, Trocen, TopWisdom, and GCode based controllers.  Supported GCode controllers,include Grbl, Smoothieware, Grbl-LPC, and Marlin.  Supported Ruida controllers include the RDC6442G/S, RDC6445G, RDC6332G, RDLC-320A, and R5-DSP.  Supported Trocen controllers include the AWC708C, AWC608, and TL-3120.  More controllers will be added soon, so if you don't see yours listed, send us a message - maybe we're already working on it!

If your controller is GCode, Ruida, Trocen, or TopWisdom based, even if it's not listed it might be supported already - Download the free trial and try it for yourself.  If it doesn't work, sometimes it only takes a day or two to make the required changes to support a new board in these existing families.

Please note that LightBurn does not support the stock M2-Nano board in the popular K40 laser. This board does not offer control of power through software - we recommend upgrading the board to take full advantage of LightBurn.
