Is that klipper.log from right after the issue? It doesn't have the MCU error in it

what is klipper running on and what other peripheral devices are connected besides the mcu?

that doesnt seem like it should be too much for a pi4... can you get a console on the pi and see if any other processes are consuming cpu resources?

Console? What is this?

A terminal window.... Command line? Anything that can give you a look at what processes are running and how much cpu is being used

I had this issue too. Problem is probably the SD card. Changed my card today and after that everything was ok again Another thing could be to much resources used on the pi but with what you have listed i dont think thats the issue

I got the same issue. It started yesterday, just after I powered on the printer and disappeared after reset. Today happened again, also at power up 🤔 All components are up to date, and I am not doing anything really special (except maybe of running the Ebb36 on CAN)
