I noticed that kerf offset doesn’t work well when using arrays with 0 mm spacing. In the Preview window you can see that LB does not push objects according to the value of kerf, so the laser cuts into adjacent objects.
And now I see that only the last object gets a kerf. I didn’t even notice it. How long has that been the case? (I use a single layer. LB version number on both my PC is 0.9.09.)
Also, “Remove overlapping lines” (regardless of kerf) is not working well.
Edit: Also, remove overlapping lines only works with 2 overlapping lines that are the exact same. Even having one longer than the other slightly, will cause them to not be removed.
You have objects that touch - if you use outward kerf offset they will overlap. LightBurn doesn’t rearrange them for you to allow for this - you have to make sure the objects have enough room between them to accommodate the kerf to begin with.
Yes, thank you! - But haven’t you thought about having an option for that?
Sometimes I put more than 100 shapes on a board. I use overlaps (with “Remove overlapping lines” function) so I only have to cut once.
Honestly I never have. It would change the physical layout of the design, and unless you’re just doing part nesting that would be a very bad thing for me to do. With irregular part shapes, it essentially becomes nesting, which is very complex to do.
