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.
