I am new to Lightburn and my laser. I am trying to snap nodes together, but they won’t connect. They will act like they’re snapped, but it won’t close the line. When I go to preview, I get a message telling me they are not closed. I don’t know what to do to get them to close. I’ve also noticed that the nodes are different. Some are a green square, some red square, and some green or red circle. What does this mean?
In the first image, I’ve circled the line I want to remove:
I think what you’re seeing is the same as those times I’ve had the same issue.
The only way I’ve found to be able to fix this is to do the following:
Select the shape that won’t close
Arrange->Break Apart. This will result in all the component segments of the shape now being separate objects.
Select all the disparate objects that make up the original shape
Edit->Auto-join selected shapes. This should rejoin all the parts hopefully into a single closed shape.
I’m hoping I’m wrong about this and that there’s a cleaner way to handle this. I welcome @LightBurn, @Rick, or anyone else from the team to review this as it’s been an annoyance for me that I haven’t yet explored in depth.
Did you attempt that with this particular file? That didn’t work from what I saw. This isn’t a normal scenario where the nodes are behaving as would be expected. I’d put this in bug-like territory but reserving that in case I’m just missing something.
This worked!! Thank you so much! I feel like this isn’t normal, though, and is something that needs to be looked into and fixed. It has been a huge issue for me since I’ve started using Lightburn. I just thought I didn’t know what I was doing and missing something. Thank you so much for your quick response and help!
For the record I know for certain that I’ve seen this with imported SVG files created in Inkscape. I’m not certain if I’ve seen this with LightBurn native shapes.
The times I’ve seen this I’m pretty sure have all been scenarios where I’m starting from a closed shape and using node edit tool to break nodes apart. It’s in the reconnecting that the issue manifests.
Ok, then it’s likely something in the editing that messed it up. This is a known issue and we’re working toward fixing it, but it’s complicated to do so because of how LightBurn stores the shape definitions internally. (explaining why it fails gets really technical very quickly)
I’ve had the same problem with jpeg photos that I imported and traced. They are recipes and I’m attempted to remove the line from the recipe cards and just leave the writing. I found the path with tolerance worked for me.
I am so lucky that I also have Vectric VCarve. When I have these problem, I export the file as svg, import it in VCarve and run the node editing there. Takes only a few seconds and I export it back as a svg file again, and the it is fixed. I have this issue four or five times a week. I wish Lightburn had the same node editing features as Vectric. But we will see what Lightburn comes up with. For me, this is the onliest flaw with Lightburn.
As a work-around, if you select the shapes and press Alt+B (break apart), then select again and Alt-J (auto join) this almost always fixes it. I’m going to look into this soon and see if I can make it behave better.
