Hi Craig - are you running the latest version of LightBurn (1.4.00)? I’m not able to reproduce the behavior you’re seeing with either a CO2 or a diode laser - both framing options are working as expected here.
What Start From mode are you using? Is this happening for every project, or only some in particular? If it’s some in particular, please share an example project file here.
Uninstalling and reinstalling LightBurn alone almost never helps, but sometimes a ‘factory reset’ can help by reverting a settings change that’s causing an issue - no setting that could cause this behavior is coming to mind for me, but it doesn’t hurt to try. Please note you’ll need to setup your device profiles again after this.
