Upgrade Your K40 Laser Engraver

Get more out of your K40 40W laser engraving machine with OMTech Laser's LightBurn-compatible control board! 

Purpose-built for 20W, 30W, and 40W desktop laser engravers, this circuit board comes preflashed with open source Smoothie firmware and additional signal ports that work just as well with most CNC routers. The ports handle our machines' default stepper motors and axis limits while providing support for even stronger add-on motors and vent fans if needed.

Further, this 24V logic board has dedicated ports that direct your laser head along its X and Y axes while recognizing their limit switches. This K40 upgrade also enables autofocusing, U-axis spinning for rotary axes, additional connections for add-on stepper motors, a 5V power feed, and nine 5V input/output signaling ports to handle pressurized air assists, external venting fans, and other laser engraving accessories.

Most importantly, this customized smoothieboard will allow your K40 box to work with LightBurn laser software running on any current and common operating system—Windows, Linux, or MacOS—so you can do precision grayscale work with any K40 laser cutter.

Good Value Screen Protector That Gets the Job Done
Model: iPad 11th A16 2025/10th
For the price, this screen protector does a pretty good job. The glass feels smooth and responsive, and I didn’t notice any issues using my Apple Pencil after installing it. The screen still looks clear, and fingerprints wipe off easily most of the time. Installation was easier than I expected, although getting rid of every tiny dust particle was still a little frustrating. I did get a small bubble on one corner, but it mostly disappeared after a day. The protector feels durable enough for everyday use and gives me peace of mind carrying my iPad around. It’s not a premium brand, but for a budget-friendly 2-pack, I think it’s worth it. Good value overall if you just want reliable screen protection without spending a lot.

Ailun screen protector WORKS Great!
Model: iPad 11th A16 2025/10th, Model: iPad 11th A16 2025/10th
Lifesaver tempered glass cell phone protector. Smooth, thin and appears like the cell itself. Reactive to cell touch and no lag time. I recently had a terrible accident from a heavy metal yeti mug fall onto my cell. I was livid when I realized my cell phone was sitting on the counter and was struck hard and thought my phone was severely damaged. I remember I had placed the glass screen protector on and slowly peeled it off. To my happy amazed discovery, the Ailun screen protector truly protected my cell phone from damage. The stick on cover took the brunt of the metal mug falling 2-3 feet above my phone!!! Saved me alot of headache, money to replace the phone which was an important special gift, and anguish. I will use this product again for future phones when I run out of cell life. Take a look of the cracked glass cover which helped me!!
