- Rebooted both computer and CNC machine

However, the problem persists. I need an expert who can diagnose the issue accurately and implement a solution swiftly. Skills in CNC machinery, networking, and computer troubleshooting are essential. Prior experience with similar issues would be greatly beneficial. Your expertise will help restore functionality to my CNC machine.
