Question “Lost communication with MCU” with no obvious reason

Printer Model

Voron 0.2-S1

LDO Voron 0.2-S1 with SKR Pico and RPi 4. Klippy.log (~1 MB, self-hosted).

Can’t find the reason for seemingly random “Lost communication with MCU” errors causing print failures at different layers.

I re-checked all the cables and disconnected RPi Camera Module 3 Wide and both Vector3D Daybreak Neo Minis with no changes.

Well, looks like checking your cables for the second or third time might be worth it: finally a completed print!
