Import multiple DXF alignement issue

LightBurn Software Questions
1

Hi,
I’m trying to import 2 dxf, one for cutting adn one for engraving.
But when I import both file they are not aligned.
Both files are using the same coordiante origin.
But they don’t have the same size. Lightburn is centering the bounding box of each file. so the 2 file are not aligned together.

Also is there an option to directly import in a specific layer (one for cutting and one for engraving) ?

LightBurn uses colours to determine which layer to place imported graphics on. Unfortunately DXF (and DWG) files use a colour index with specific fixed RGB values which don’t exactly correspond to the LB layer colours, so LB will find the closest colour match to determine which layer to put something on. I put together a DXF to LB colour map (see below). I think I checked all of them but I can’t guarantee anything!

Thanks for that.
unfortunatly my export don’t allow me to created multiple color. But I’ll check if I find a tool to change the color of a DXF file.

The alignment issue is a bit a of pain. I’ve added a specific form that I align between my layers. This work. but it’s an extra step.

What software are you using to create your DXF?

It’s Kicad.

Ok, yes, I think you’re pretty limited with your options there :frowning:

Maybe you can open the DXF in Inkscape to tweak it.
