LightBurn automatically creates backups as the prefs change, and stores the last 50, but it hasn't been obvious, or simple to find them. If this happens, the prefs get reset, so it might seem that you've lost all your devices and settings. Backups & BrowsersĮvery once in a rare while, the preferences file in LightBurn may get corrupted. You can't edit the text, but for just running the file or tweaking cut settings, this will work, and should save you a few trips back to the house.

This release of LightBurn stores a copy of the generated text shape in the project file, and will use that if it can't find the font. If you use one machine to design, and another to run the laser, you might have run into the problem of not having the same fonts installed on the laser system, so when you load a project, the text looks wrong.

The specific windows enabled are also saved / restored, so the console window will hide for a CO2 system, and reappear for diodes. Your speed / units settings are now remembered with the laser, so switching to a CO2 from a diode will switch you from mm/min to mm/sec (or whatever you use), and auto-load your material library for the machine. If you have more than one laser, and they're different types or wattages, there are new features in LightBurn that will make moving between them cleaner, and we'll be continuing to improve this in the future. (for anyone anxiously awaiting the upcoming galvo/fiber release, this isn't it - not quite ready yet) Users with multiple lasers

There are lots of new things in this release, so we'll cover the big ones here, then list the rest.
