BTT Octopus 1.1 can bus setup

[lukics]

I was looking in different threads and did not get the final information on how the onboard can bus interface of the BTT octopus 1.1 could be used.
In one thread (BigTreeTech Octopus V1.0 and V1.1 Information) it is stated that extra powerful HW is needed in order to use this feature.
I would like to use a PI3B so this is definitely not a powerful HW.
Did anybody implement this setup, and connected the tool head over can bus directly connected to the BTT Octopus?

 

[Indeed]

I use the Octopus in "USB to CAN bus bridge" mode.
