This video details the install or retrofit of a Voron 2.4 core-xy 3d printer to canbus via the BigTreeTech SB2204 / SB2209 and the BTT U2C Canbus interface ( can bus ) for the Raspberry Pi 4. This shows how to update and configure Klipper onto these cards, mounting, cables, umbilical and reconfiguration of the printer.cfg files.

Extra special note:
If you are using the SB2240 and you are getting under voltage errors in Klipper, please have a look at this to resolve them:

Special note:
Correction, at about 9:41 in the video I state I'm going to flash the u2c but instead I just flash the SB2240. That's exactly what I did, but my voice over is incorrect. Please ignore what my narration states until I can fix and upload a newer video.
A Raspberry PI 4 or CM 4 are highly recommended. People have reported communication issues with the Raspberry PI 3. Devices more powerful than a Raspberry PI 4 are probably fine as well.
