USB problem Not connecting to Thunderlaser with Ruida

I am having problems using an older laptop than normal, I have done a windows update and checked with device manager for up to date drivers. Any suggestions please. It does work intermittently but not usually first time.

install the usb drivers from the lightburn setup

does that mean installing lightburn again

If it works sometimes, it’s not the drivers. I’d suggest finding a better / newer USB cable first, and see if that fixes it.

Yup that sounds like a bad usb cable

Bad USB cable (poor quality or too long), or check the extension cable that connects the port outside the case to the controller inside. If that gets loose or the connection is poor that will cause this too.
