I’ve started having issues with Lightburn communicating with our Bodor laser, with a Ruida controller.
I believe they’re firewall related, as bypassing the firewall resolves the issue, but I have also applied specific rules for lightburn.exe and SendUDP.exe to be allowed.
When sending a file to the laser, it starts the process, asks for a filename, will check and notify if it needs to be overwritten, and then fails the upload after a short time. If I bypass the firewall, this process completes without issue.
Interestingly, if I ‘start’ the exact same file instead of sending it to the machine, it starts immediately and completes the cut without issue.
Is there any other background processes, ports or helper applications that need access through the firewall for Lightburn to be happy?
