I have changed computers and reinstalled Lightburn but it wont connect to my laser, it connected and worked great on the old computer but now it wont connect to the lase, I have tried USB and also Network cable but neither works. Any suggestions please?
You may need a driver on that computer for USB. There is a checkbox at the end of the LightBurn to install the Windows version. Installing Lightburn - LightBurn Software Documentation
This post helps with connecting via Ethernet.
tried this to the letter but still not connecting,
I re-installed lightburn, this time I clicked the FTDI button and its now working on the USB. Many thanks for your help,
