Klipper restart : 'Got EOF when reading from device'

Sorry, I have no clue what’s going wrong.
I noticed, you use a whole bunch of macros. Did you write all the macros by yourself?

Your bandwidth is pretty high. Might mean nothing, but it correlates a bit with your two attached logs.

I would start over without all the macros. Just write the few needed ones by your own. Benefit is, you know exactly, what you want to approach.

Good luck, hcet14
