1. The CB1 couldn't be connected to the PI TFT screen. The DSI/CSI port will only work while using CM4.

2. The PI4B should be used with CB1, CB1 eMMC or CM4 core board to run Klipper.

Fast shipping

I got two orders from Biqu. Both arrived fast. I ordered upgraded parts from tronxy 40 days ago that still haven't reached the dock in Canada. Biqu doesn't skimp on shipping. Great company to do business with.

Pi4B v1 and CB1 v1 Klipper powerhouse

I bought 3 CB1 modules and a M8P board last year when they came out. I struggled even finding what to learn let alone where to learn it. But I am no spring chicken and I fought through it from the bottom to wherever I am today. I can't write my own macro yet but I will be able to soon. And once I stopped tripping over the first few steps and really paid attention, it mostly fell into place quite easily.
The CB1 in a Pi4B adapter is a great setup. It is very stable and very responsive. I also have an MKS Pi which can do much of the same job, but I think the BTT rig is easier to work with, faster in every aspect, and has better support. It WAS frustrating at first, but that was not due to the hardware, or even the software setup. I just didn't know what I didn't know yet so I simply bashed my head against the wall (figuratively, mostly) until klipper started to make sense.
If you are under 100 or at least above the dirt, and you want to learn how to use this awesome stuff, dive in. The water is great.
