My lightburn doesn’t connect to my laser co2 laser

[Hamad909 (Hamed)]

My lightburn couldn’t find my device. I have tried the manual way, but it was all in vain.

This is the laser machine which i use

This looks like a K40 type. These usually use a control board that isn’t grbl and is not supported by Lightburn…

Have you used it with the supplied software? What is the name of the software that came with it?

If you wish to use Lightburn, you might have to upgrade the machines control board. This is common with these … Here’s a couple of threads… there are plenty more.

K40 Upgrade and License

Have you replaced the controller for the machine or otherwise purchase a K40 with a pre-upgraded controller? And if so, to what? If you have not, then be aware that K40 lasers come with boards that are not compatible with LightBurn. They will not work out of the box.

New Laser Setup Choices

I also have the Atomstack A5 Pro and had the same issues with cutting. I came across a recommendation in this forum to look at the M50 upgrade module which despite its price I picked up. Easy to swap in and it did solve my cutting problems. Much faster and cleaner. Happy with the Atomstack now.
