Laser project DXF file generates no g-code

Software Snapmaker Luban
1

I am trying to isolation route a PCB and imported a dxf. If I set the toolpath to “along the path” g-code is generated normally, but if it is set to any form of fill no g-code is generated at all. The upload doesn’t support dxf files so I can’t put my file up here but I have screenshots of the work window and preview below *I have removed the blank preview image because new users can only have one image pasted into a post*. I have tested and my Artisan does nothing with the file if I try to run the engraving process. As a new user I cannot upload attachments, so generated g-code is pasted to the bottom of this post.

I’ve added three back ticks to your code for better readability, like this ` three times at the beginning and end.

Try another file format maybe inkscape vector would work.
Unfortunately there is no or not much development of Luban ongoing.
Maybe opening a ticket would help to address this issue:

Yep, straight from the START to the END. Interesting that it goes START → END → START → END twice.

Not terribly helpful, but there are guides on the forum for using other software. The one I remember off the top of my head is Lightburn, with a guide at 1064nm IR+20/40W + Lightburn Guide . Looks like it’s paid software though. I’m sure there is free software out there too, I’m just drawing a blank.

The free software you’re likely thinking of is LaserGRBL. I should probably look into it and see if I can make it work well with the snapmaker. I assume it’ll mostly be finding a way to have a better header/footer gcode.
