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.

Disappointing Dog Toy – Short-Lived and Ineffective
I purchased this dog toy hoping it would keep my dog entertained and engaged, but unfortunately, it has been a huge disappointment. The first one I received only worked for about an hour before completely stopping. I decided to give it another chance and ordered a second one, hoping it was just a fluke. Unfortunately, the second one lasted even shorter—only 30 minutes—before completely ceasing to function. It no longer vibrates, rotates, or interacts in any way. Even when fully charged, the toy barely lights up and doesn’t do anything useful. This is a terrible product, and I’m genuinely shocked by the positive reviews. Save your money—this toy is not worth it.

My dog loves it
My Aussie loves it and he is a tough chewer as well, so it goes great with his hyper reactive personality. Durability could have been a little better, sometimes I have to take it apart and make sure it’s still in a good position because my dog will pick it up and drop it. With no cushion it did start malfunctioning at about 2 weeks. However, it does still work fine and he loves it even without the movement. Note if you put it in a sock to protect it, my dog goes dangerous and held the sock and created a slingshot lol.

My Rottweiler loves it!
My Rottie plays with this for hours at a time! He loves it! It fun to watch too! The plastic is high quality and has lasted for 2 weeks, so far. That pretty good for a Rottie toy! He loves the lights, vibration, and the fact that it rolls away. So fun!

Pass on this one.
It's hard plastic, which doesn't make for a fun experience for either the dog, or our floors. It doesn't stay charged for long either. I wasn't impressed at all...and neither was the dog.
