Fly-Super 8 Klipper host CANbus configuration
Edit me
Klipper Host CAN0 file configuration
Important: This guide assumes you have a working Klipper host installation on a Fly Gemini, Fly Pi, Raspberry Pi or compatible device. If you don’t have a working installation, please use kiauh
- SSH into your Klipper host and create a new can0 file in the /ect/network/interfaces.d folder
sudo nano /etc/network/interfaces.d/can0 - Enter the following information.
allow-hotplug can0 iface can0 can static bitrate 500000 up ifconfig $IFACE txqueuelen 1024 pre-up ip link set can0 type can bitrate 500000 pre-up ip link set can0 txqueuelen 1024
Note: The bitrate should match the one used on your tool boards. It can be 250000, 500000 or 1000000. Only use 250000 if you run into timeout issues and cannot fix them by improving the wiring. 500000 or 1000000 are preferred
-
Enter Ctrl+X to save the can0 file
-
Reboot your klipper host.
-
Reconnect to your klipper host using SSH and send
ifconfig. Make sure the can0 interface is listed. -
This should be all you need to do if you are using a Fly UTOC-1, UTOC-3 or Fly-Super8 in CAN mode. Other CAN bus adapters may need aditional configuration steps.
