Hello, I need some help please. I have upgraded my tool head from an Afterburner to a Stealthburner and added a sb2209 tool head can-bus board.  My current mainboard is an Octopus 1.1 which was running great before the upgrade.  


BTT Octopus 1.1

RaspPi 4B

SB2209 can-bus tool head board.



Pi (usb-a) to Octopus (usb-c)

Octopus (usb-a) to Pi (usb-c) for power.

Octopus (rj11) to sb2209 tool board, and 24v power supply to sb2209 tool head board.

Firmware loaded:

CanBoot for Octopus flashed with STM32cube menuconfig below


CanBoot for SB2209 flashed with STM32cube menuconfig below:


below is some additional info:

pi@mainsailos:~ $ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
