Cannot Connect Octopus Pro to Pi

Hi guys, I'm very new to this community and admittedly a little over my head when it comes to this kind of custom 3D printer and I bought it looking to expand my experience and knowledge. I have been stuck trying to connect the Octopus pro to my Raspberry Pi. I keep getting the error mcu 'mcu' : unable to connect. I have tried searching online and through this discord but what works for others doesn't seem to be working for me. I could really use any help I can get. Thanks in advance!

did you work through https://discord.com/channels/582187371529764864/1046952693480038500 ?

Yes, although I do not know how to SSH into my raspberry pi but I have gone through all the other points

What operating system is the computer you are using to connect to the mainsail interface (ratos.local)?

fair-rose•2y ago

Windows 11

ok, so open up powershell and type in ssh pi@<IP ADDRESS> where <IP ADDRESS> is the ip address of your raspberry pi

It should look something like this

sorry if this is a dumb question but how do I get the ip address from the Pi?

blacksmithforlife•2y ago

nope, not a dumb question. Since you have the web UI working you can grab it form the machine tab

okay i connected but its now asking for password

blacksmithforlife•2y ago

default password is raspberry unless you have changed it when typing the password it will not show anything. When you are done, just hit enter

blacksmithforlife•2y ago

ok, so now you can continue with the FAQ

I would first run lsusb and see if it is connected so I see
