What is the problem?
OctoPrint doesn't detect the printer
What did you already try to solve it?
I am a new user and I have OctoPrint running on my windows pc. I know it isn't conventional, but I already have my pc running 24/7 so I didn't think it made sense for me to buy a Pi for this situation. OctoPrint is running fine, I have my webcam hooked up and I even enabled the Virtual printer to troubleshoot and confirm that it was all setup correctly. The only solution I've been able to find for this issue is "try another USB cable", I've tried at least 5, and I know the cables all worked because I can hear the device connected sound on my pc whenever I plug the printer in. I've updated the OS, as well as updated OctoPrint through the web interface. I have no idea what the solution is.
