I’m experiencing a problem with LightBurn. I recently got the software and have been using it for about a week. During this time, I encountered some issues with my PC running Windows 11, but LightBurn itself never had any problems. After reinstalling Windows 11 and completing all the necessary updates, I reinstalled LightBurn.
However, just a couple of days ago, LightBurn began to freeze, lag, or crash. I have checked for updates, but there are none available. Currently, I have it installed on my main PC for designing, and I use a shared file location to transfer designs to my laptop, which is connected to my Falcon 2.
Whenever I add items to the workspace in LightBurn and try to move them, the program freezes or lags dramatically, like I’m experiencing an FPS of 2 for several seconds. I’m looking for solutions to fix this lag or alternative programs I can use.
Additionally, I should mention that the version of LightBurn I’m using is still in the trial phase. From what I understand, the trial version should function the same as the purchased version, but I’m hesitant to buy it due to the issues I’m facing. For now, I’ll continue using the trial version.
If anyone has experienced similar problems or can offer some guidance, I would greatly appreciate it. Thank you very much for your time!
Without knowing your operating system, advice will be limited. But I am pretty confident Lightburn is not your problem. Unless you obtained the copy from an unauthorized source.
Thank you for reporting this and for sharing the files.
I’ll take a quick look and see if I have enough to move toward replicating the behavior.
I assure you, this is true.
This is good advice and more important than it would seem.
We’ve also seen some aggressive anti-virus software that scans changes to memory when LightBurn is working. Watching the Task Manager in Windows might show that a process is overwhelming the CPU.
I’m unsure what you mean by ‘items’. If you’re moving large high-resolution images they retain all the image data until the project is sent to the engraver. Comparing the GCode file size to the LightBurn file size should tell us if this is happening.
In LightBurn, click File, and click Save GCode (for the 40W Falcon laser engraver) and save the file on the local drive - somewhere convenient (without OneDrive in the File path). Then click File to save the LightBurn project near the other file. Compare the File Properties or use a ‘Details’ view of the directory to see the file sizes. Let us know what you see.
Local storage is important because antivirus software tends to manage it better and the data can move much faster while the software is performing tasks.
I’ve seen a couple of Windows 11 computers where the Desktop was a fourth or fifth sub-subdirectory of Onedrive. It generated a few unanticipated behaviors.
