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.

Upgrade your DIY laser engraver with the OMTech K40+ motherboard today!

Quick and easy claim process
We filed the claim and they sent us a return label within a day. I sent back the unit and in the same day, they issued a refund. Amazingly easy and fast. Will definitely use their warranty services again.

Definitely worth having the peace of mind of the support from the Asurion team.
Good value and mostly worry free. Took several more steps to complete than originally described. I had to resubmit material and pictures a few times before everything was finally accepted, but in the end I was satisfied with the results.

So worth it - painless
I decided to get the extended warranty for my Black & Decker hand vac. When it stopped holding the charge, I reached out to Asurion. First of all, I love how I don’t have to search through papers and emails to try to find my warranty. It’s right in my Amazon purchases. They immediately started a conversation via text message with me. It was so straightforward to get the information to them. Then they sent me a return label, then Bada Bing, Bada Bang, I sent back my malfunctioning hand back, and they sent me an Amazon gift card. I use the gift card to purchase a New Hands back because I can’t live without it. Everything went so smoothly and it was so quick I highly recommend it for any electronics that you rely on and you would replace if it became inoperable.

Did the right thing to resolve my issue.
Covered my cost with little hassle. Started down the path of going back to manufacturing company but decided to just do a refund. The product was a floor vac that died.
