Then the settings I posted are the settings you need to use for your Octopus.
The BTT EBB36 will need CanBoot loaded via USB-C, a jumper on the 120ohm header, and USB-C power. See “Loading CanBoot” in my Octopus post for DFU loading the CanBoot firmware to your BTT EBB36. See below for CanBoot and Klipper firmware settings.
You will need the following:
• USB-C cable between your RPi and the Octopus.
• RJ12 or RJ11 on the Octopus to the BTT EBB36 black connector.
• 24Volts to the BTT EBB36 to the black connector.
After setting up the Octopus Pro (CanBoot & Klipper) and getting CanBoot on the BTT EBB36.
Disconnect to USB-C cable from the BTT EBB36 and connect the CAN bus (CAN_L & CAN_H to the same) from the Octopus Pro to the BTT EBB36 (black connector). Connect 24Volts and ground to the BTT EBB36 (black connector). Remove the USB-C power jumper, or this may cause problems.
Power up RPi, Octopus Pro, and BTT EBB36.
via ssh terminal, type in the following: sudo nano /etc/network/interfaces.d/can0
copy this from here and paste it into the terminal.
allow-hotplug can0
iface can0 can static
bitrate 500000
up ifconfig $IFACE txqueuelen 1024
then Ctrl X
Y Enter to save the file.
then sudo reboot
ssh back into your RPi.
copy and paste this command: python3 ~/CanBoot/scripts/flash_can.py -q
Record the two UUIDs, the UUID that states Application: Klipper is your Octopus Pro, and the other is your BTT EBB36.
Ensure you have compiled your Klipper firmware for your BTT EBB36 before the last step.
copy and paste this command: python3 ~/CanBoot/scripts/flash_can.py -u
Replace the with the UUID of your BTT EBB36.
BTT EBB36 V1 [STM32F072]
BTT EBB36 V1.1 [STM32G0B1]
