Unfortunately I have not found anything in the forum and therefore allow myself the following question.
Lightburn suddenly changes size when engraving or cutting.
Except for the regular updates, I have not willfully changed anything in Lightburn or on my CO2 laser. Before that, everything was accurate to the millimeter.
I have not set or changed an offset.
I am already looking for 3 days and do not know where I can control or adjust something so that everything is correct again.
I tried to calibrate the axes to fix the error, now the laser whispers completely as it wants. Stupid as I am, I have not saved or photographed the file beforehand.
Oh man, can someone help me please?
I would reach out to the supplier and ask for a backup file of the original controller settings shipped with this unit. They should have what all the information about how they first set it up. If they cannot supply a backup file, this might help: Configuring a Ruida - LightBurn Software Documentation
LightBurn actually saves a backup copy of your settings whenever you edit them. Click File > Open prefs folder, and look in the ‘Backup’ folder in there.
The files will start with the name you gave your laser (probably Ruida), and then a datestamp, with the “lbset” extension (LightBurn Settings file).
Copy a recent one out of that folder to somewhere you can find it, like your desktop, then go back to Edit > Machine Settings, click ‘Load’, open that file, then click ‘Write’ to store those settings back to the controller.
