Hello, I was using the interface with no real problem till today. When I move the interface, I get a disconnected warning on the screen and everything stops responding. Move the interface, and it works for a bit. Seems to be a connection issue in the wire. Has anyone had issue with the wire from the GRBL controller to the interface? Or am I barking down the wrong tree. I guess I could run a continuity tester and check the wire. But thought I’d ask first since the tester isn’t here at the moment. thanks!
