Question about E80 laser module on NEJE Max 4

Hello all, I have just a simple question here, what’s the focal distance of the E80 for cutting, and what’s the focal distance for engraving? Are these distances the same in both cases? Thanks for the help!

Hello @Miguel_Rossier

Here you can see how to focus.
Wiki Neje

And to directly answer it, 25mm from the bottom of the module. You can check online for cut/engrave tests and check.
Usually for engraving, you do the surface of the material. With cutting, i saw in a new video from Neje that you do the same, but in the documentation it tells to go 1mm under the surface.
Here is also the video from Neje to let u know how to properly set the pre-focus Youtube Neje

Have a nice day.
