JCZFiber Laser Connection No Longer Connecting

LightBurn Software Questions
1

I have a dedicated computer that I use to run a Cloudray laser; it’s been running Lightburn for over a year now without issue.

Mysteriously, Lightburn can no longer detect the laser when turned on/plugged in. I’ve tried rebooting the computer several times, reinstalling lightburn, etc.

Switching USB cords did not make a difference. When plugged in, the device manager registers BJJCZ Device > Laser Mark Control Board V4. There is a small yellow triangle which may be the issue? “Windows cannot verify the digital signature…”

I plugged in a different computer, Lightburn and the laser are fully functional, the issue is specific to the laptop.

Any suggestions? Different driver install?

I think you need to try performing a driver swap as described here:

Thank you Jess, that worked.
