I'm struggling with getting my Ender 3 Pro connected to my Raspberry Pi 4 via USB. The connection just doesn't seem to be established. From what I've read, it could be any number of things.. but I was hoping someone here had some input.

Thanks!

So I might not be of any help, but probably need more information. Are you running stock or have you made any modifications or using a custom firmware? Are you able to connect via network to Octoprint at least? Try different usb cables?

Sorry, yeah I realized my post was super light on info - the printer is in the basement and far away :)

Where I'm at:

  • Multiple USB A <-> Micro-USB cables were tried
  • RPi4 turns on, I can access Octoprint just fine. Octoprint says it could not recognize any connected printer
  • E3Pro turns on just fine, is completely stock and has not been modified in any way.
