Summary & FAQ

What are the advantages of CanBoot?

It allows flash firmware by canbus directly, no need to plug Type-c cable anymore after you done this.

Note

Make sure you have the lastest klipper version. In some test the default version of CB1 would cause out of control heater issue.

Configure CAN Interface with U2C

Connect U2C with a USB cable.

sudo nano /etc/network/interfaces.d/can0

Input these lines.

auto can0
iface can0 can static
    bitrate 500000
    up ifconfig $IFACE txqueuelen 1024

If you are using USB-CANBUS bridge, use this instead.

allow-hotplug can0
iface can0 can static
    bitrate 500000
    up ifconfig $IFACE txqueuelen 1024

Save after modification (Ctrl + S) and exit (Ctrl + X)

Enter sudo reboot to restart.

With this command you can check if configure CAN insterface right, it should show can0
