Hello, I'm completely new to 3d printing and Linux and have what I hope is a simple problem. My setup is: Ender 3 printer Raspberry Pi 3 B+ running OctoPrint 0.16.0 Ultimaker Cura 4.0 I was able to flash the SD and see Octopi Server on my network and I connected OctoPrint Server to Cura 4.0 through the plugins menu from Marketplace. When I connect to the Ender 3 with mini USB the lights come on and it appears connected but the OctoPrint option in Cura gives error "Printer Offline". Is there a setup step I missed? A guide or walkthrough would be very helpful. Thanks, Joe
