<p>Well.... turns out I'm kind of an idiot but not entirely...

First thing you should try is to see if you can establish a connection to the controller boards over USB (beware of Baud rate and USB port location/name). Use Pronterface or other [console interface](https://3dprinting.stackexchange.com/questions/10573/) and try to manage the printer from your computer/laptop. If that works, OctoPrint should also work, we may need some screenshots of the connection and the failures shown by OctroPrint.

So, long story short, I was using the SKR Mini E3 V2 and had a load of weird issues which lead to it not being able to connect via a Raspberry Pi 3B via USB (using OctoPi distribution).

I tried updating firmware and it would connect to the printer but failed whenever I did anything i.e. heating, moving an axis, etc. I eventually managed to find a heating error. I changed the thermistor on the hot end, realized it was complaining about the heated bed so changed that too, then the Pi just wouldn't see the board.
