CB1 secondary MCU?

General Discussion

I have a Manta E3EZ with a CB1. I’ve followed the document RPi microcontroller - Klipper documentation to turn the raspberry pi into a MCU. I have done this with a previous board SKR3 quite easily. Yet with the CB1 I can’t seem to figure it out.

Has anyone else successfully done this before? I’ll supply my log but all it says is can’t find MCU:rpi

caused by:

cs_pin = rpi:None

I do not have the CB1, but following might provide some insights:
