We have verified a bug with the macOS release of LightBurn 2.0.03 that only affects users with BSL controllers (EZCAD devices are unaffected). This issue does not affect the Windows LightBurn release.
We recommend macOS users with BSL devices downgrade to LightBurn 2.0.02 - Download LINK - install as you would any LightBurn release.
The issue is caused by a bug in a BSL-provided library. We are awaiting a new library from BSL to fix the issue, which will be published with LightBurn 2.0.04 as soon as possible.
To check whether this issue affects your laser, click the Devices button in the Laser Window and check the device type in the list — only devices marked BSLFiber are affected.
Example hardware: Mr.Carve M1, GWeike G2, Atomstack M4, some Monport galvos, Atomstack M4.
