Thanks for posting on the Darkly Labs Community site!
What you describe is the intended behaviour of layers within LightBurn. You can change this so that layers will revert to some predefined default values though, via the Edit > Settings - File Settings then enabling ‘ Load default layer settings on new or restart ’.
You can then assign defaults to individual/all layers via the Cut Settings Editor (double click a layer in the Cuts / Layers tab):
In either case, layer settings are never copied with an object.
Without the File Setting option enabled, layers in a file will ‘remember’ the last settings used - even if this was from a different session/project. If you change the settings and save the file, these new settings will be saved with the file itself (so if you open the file, it will have the saved settings), and also loaded as the default settings for the next time you use the layer in a new file or add a previously unused layer.
The logic behind this is that often people will have specific layers loaded with settings, so they might always use the black layer for cutting 3mm Poplar Ply, and the green for cutting 6mm Poplar Ply. This is somewhat similar to how many other laser software packages work. Personally, I do not use layers like this.
If you are concerned about incorrectly set values being used by mistake, you could enable the File Settings option mentioned above and assign a default setting with a Power of 0% - Just remember if it doesn’t cut a layer, this is why!
I hope that clarifies how LightBurn handles layer settings in these situations. Please don’t hesitate to let me know if you have any other questions.
