Cannot Connect to any of my printers
I have 2 Sidewinder x1s and a Ender 5 Plus, I downloaded Repetier Server today on a raspberry pi 4b and cannot connect to any of my printers it seems. I name the printer then change firmware to Marlen and there are so many port options (/dev/tty0 to 63 and more) but did the trick to plug in the USB and see what populates, 3 options pop up( /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0, /dev/serial/by-path/platform-fd500000.pcie-pci-0000:01:00.0-usb-0:1.3:1.0-port0, and /dev/ttyUSB0) i have tried all 3. all i get for ever is "Waiting for Connection" tried different cables printers ports nothing works! HELP!!!!
