OctoPi not finding printer (ender 5 pro)

[DLTPrintz]

What is the problem? My RPi4 boots up find, server connects no issues, but it fails to recognize my printer.

What did you already try to solve it? spent hours combing through online posts and guides for similar issues. Have determined the following.
-Power supply is fine.
-Installation of Octopi is fine
-network is fine
-cable seems fine

Hi

Turn your printer and pi, log into your pi via ssh, disconnect your printer, connect it again, enter dmesg | tail -n 20 and post the output here.

Also try this

Put tape on the 5V pin - Why and how

First of all this whole tutorial isn't a mandatory mod - you just need it if you run into issues (weird things are happening and you've already ruled out the more common suspects) or if the always running fan and illuminated display (even when the printer is turned off) disturbes you. I'm starting with the why part: If you connect a 3D printer via USB to your Raspberry Pi it can lead to all sorts of power related issues. Most of the time those issues occur only if you turn on your pi before…

I have tried the tape method now, but that did not work.

as well, here again are the logs you asked for. Followed your exact steps.

Thank You!

Mhmm there is no connection detected at all.
I guess you already tried different USB ports on your pi?
Next I would test it on your pc / laptop with something like pronterface.

Maybe a faulty USB cable?
