Hello,
I’d like to report an issue with LightBurn 2.1.01 using an OMTech Polar CO2 50W connected on Mac.
After updating to version 2.1.01, when I send/start a job from LightBurn, the laser goes into an error state: the indicator light turns red, and in some cases it seems to start a different/previous job instead of the one I just sent.
I also tested the latest beta version, and the same issue occurs there as well.
At first I checked the water level, water flow, air bubbles in the cooling circuit, and safety sensors, but the issue does not appear to be hardware-related. After downgrading to a previous stable version of LightBurn, the laser started working correctly again.
I also have another Mac where LightBurn has not been updated, and the laser works normally on that machine.
So the issue seems to be related to LightBurn 2.1.01 and the current beta version, or to a compatibility problem introduced with these versions when using the OMTech Polar 50W on macOS.
Could you please check if this is a bug?
I’m available to provide logs, screenshots, videos, or run additional tests if needed.
Thank you.
