Can't get Octoprint to connect to Printer

What is the problem?

Cant get Octoprint to discover printer

What did you already try to solve it?

Using a raspberry pi zero 2W, seems to be working right and I can open up octoprint, but it wont recognize printer. Tried an OTG connector and a USB connector as well off of a USB bank.

Have you tried running in safe mode?

no

Did running in safe mode solve the problem?

no

Hello @Cody_Heller !

What printer do you want to connect to?

Creality printers can be a bit picky when it comes to the USB connection.

You may try wit/without the SD card in the printer SD card slot.

Also you may 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 …

Also, check the USB cable. There are some cables existing just for charging, without data wires and can't be distinguished from the full populated cables.

Im trying it with printer SD card out now and an OTG cable with the usb bank not attached to the raspberry pi, just trying to see if I can get it to recognize. Still nothing. Give me State: Offline after error every time I try to connect still

[Cody_Heller]

not sure if anyone else has any ideas

figured it out, data cord combined with using the wrong micro usb port to power the PI.
