Hello, i have the problem that my ResPi dont connect to my Octupus v1.1 Mainboard.
Both are connectect over USB and i can see on my Pi that the MCU is showen in the Serial. I flashed my MCU over an SD Card. Any Ideas how to fix this?

You have an issue with Cartographer board, not Octopus:
"mcu 'scanner': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb-cartographer_cartographer_31001C000F43304146393320-if00: [Errno 2] No such file or directory: '/dev/serial/by-id/usb-cartographer_cartographer_31001C000F43304146393320-if00'"

#

try to comment [mcu scanner] annd [scanner] sections in printer.cfg asnd try it again

#

and if it will works, change
serial = /dev/serial/by-id/usb-cartographer_cartographer_31001C000F43304146393320-if00 in [mcu scanner] section to value showed in /dev/serial/by-id

#

correct one is: serial = /dev/serial/by-id/usb-Cartographer_614e_31001C000F43304146393320-if00
