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.

Great quality product
Size: iPad A16 11th/10th
This is a great quality product that is easy to apply. It's scratch proof with no glare on the screen. We were able to apply this screen protector with no bubbles on the screen. It's heavy duty and will prevent screen cracking if this is dropped. I would definately recommend this product!

Screen protector
Size: iPad Air 11" M4/ M3/M2, Size: iPad Air 11" M4/ M3/M2
I’m really happy with this screen protector for my iPad. The quality feels really good, and it fits perfectly on the screen without affecting the display quality or touch sensitivity. I was worried it might make the screen look dull or reduce responsiveness with the Apple Pencil, but everything still works super smoothly. It also helps reduce fingerprints and keeps my screen protected from scratches, which gives me peace of mind while carrying it around daily.

Good protection, but some bubbles remain
Size: iPad pro 13'' 7th (2024), Size: iPad pro 13'' 7th (2024)
This screen protector does a great job protecting my iPad. It feels solid and the screen still looks clear and responsive after installation. Overall, it gives good peace of mind for daily use. Installation was simple and straightforward, which I really liked. It didn’t take much time and everything you need is included. The only downside is that there is always a small air bubble that stays under the screen at a certain angle and doesn’t fully go away. It’s not a big issue, but worth mentioning. I’ll attach photos after installation so you can see how it looks. Overall, a good product with minor imperfections.
