Jtech 7w, 14, 24w, and 44w, Lightburn Cutting Library

I listed my Lightburn Libraries here for the 24w, 14w, and 7w Jtech Lasers:

How to install them:


@OnefinityCNC are these the files you referenced in your lightburn video?

@onefinitycnc Is there any other speed and power charts we can reference? These files don’t really include any solid woods.

jtech may have more on their website or forums

Is there an updated library for the 14w laser?


were you able to find an updated library for the 14w? I just got mine in the mail today.


Thanks, Mike! This will help out a lot. I’m just getting started and only have my MDF dialed in.

You are very welcome! :slight_smile:

Do you have a library for hardwoods?


I am looking for a 24w library. Who is the “Jennifer” you spoke of in your previous post?


Hi!!, I need this library too, I just received my 24W JTECH Laser. If you get it can you please share it with us, thank you in advance :).

Did anyone finally get the 24w library?

I have had no luck in finding the LB material library. I have pretty much abandoned LB for Aspire since Vectric supports the post-processor. However, speeds have been trial and error. If anyone finds the library or has suggestions for speeds, please post.

So I am guess no Library 24 w

Anyone find that 24 watt library? Kind of ticks me off that i spent the extra cash for the 24 watt and no library is available.

is this recent? I sent them an email about a month ago and they did not have anything for 24 watt

Just updated my post with the 24w, 14w, and 7w libraries I have. This is all I have and I don’t have any other settings or files somewhere.

These will get you at least a starting point. Your laser and my laser will be a bit different, so not every setting will be 100%, but should be a close start!
