MCU / Printerboard: Octopus 1.1v
klippy.log
Hi everyone, I have tried to connect my Octopus 1.1 to the raspberry pi 3 via GPIO, but I continue to receive this error:
The klippy host software is attempting to connect.
and then:
mcu 'mcu': Unable to connect
Does anyone know why?

Hi @Nathanub ,
Generally, using an MCU path like /dev/serial0 isn’t recommended. What’s the output of (in SSH):
ls /dev/serial/by-id
I know it’s not recommended, but I broke my USB port 
Anyway, it returns:
nathanub@raspberrypi:~ $ ls /dev/serial/by-id
ls: cannot access '/dev/serial/by-id': No such file or directory
