I recommend following the directions at CANBUS - Klipper documentation , and use the /etc/network/interfaces.d/can0 settings exactly as stated there. Restart the rpi, and then run the ip link show can0 and verify you see qlen 128 before proceeding with further tests.
I used the EXACT klipper suggested settings for can interface file… And for the first time, my printer booted up AND connected to the ebb36 without needing to SSH a command. I’ll be heating up the bed and home/probe everything first thing in the morning. The can network is reporting the proper txqueuelen. I removed the pre-up ip link set can0 type can bitrate 1000000 pre-up ip link set can0 txqueuelen 1024 lines
