Thank you for providing this report. Which model Ruida is used in this laser? You should see a sticker on the white control box inside the cabinet. Which firmware version is running that controller? You should see that listed on the display panel of the laser when you power it on. And what version of LightBurn, running under which OS?
The team has been collecting information around similar reports, yet we have not been able to reproduce on our hardware here. Anything you can think of, please share to help us track this down, is greatly appreciated.
You can try an earlier release of LightBurn, to test results.
