I have a 900x600 laser, and a file with about 230 individual parts that will need many different sheets to complete.
When I import my dxf file, I have a heck of a job going through and organising which parts fit and selecting/deselecting which to cut.
So, I have to do all of that outside of Lightburn and then bring the nested file in to cut.
One thing I like about Lightburn is that I rarely have to go out to a third-party app to get things done, so a built-in nesting tool would be a real boon.
There’s a few open-source ones to look at that could become the basis for a Lightburn nesting tool:
