When will Lightburn let me remove the line or circle but leave the text. I use Inkscape to do this then I import into Lightburn.
Once you have your text how you like it, click the text then go to edit -> convert to path, and then you can move or delete the line or circle.
You can remove it already if you convert the text to a path (as Blake shows above). If you want to be able to edit the text, you have to leave the path it’s connected to. It’s very simple to put the circle on a different color layer and set it not to output.
