Uploading G-Code - Stays Red
Good afternoon everyone. I have been using Repetier server for about 2 weeks now with zero problems. I am running the server on a Raspberry Pi 3. I had to shut down my Pi this morning to move it. After bringing it back up i tried to upload a print and it just stays "ping/red" in the server GUI. I never get the option to actually print. Any suggestions on what this could be?
