MCU 'mcu' shutdown
I haven't Printed in Months did not change anything and now every time i try to start a Print it says "MCU 'mcu' shutdown: Timer too close
This often indicates the host computer is overloaded. Check
for other processes consuming excessive CPU time, high swap
usage, disk errors, overheating, unstable voltage, or
similar system problems on the host computer.
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown"
Anyone got an Ide why its happening now ?

coul a loose connection cause this problem ?
restarted the print again and the cpu ussage is about 10 percent and memory 45 percent no undervolting and so far it didnt crash
didnt change anything
temps from the pi and the toolboard are below 40
I would try to change the SD card, if you already addressed the possible problems described in the error message.
well that sucks but i could give it a try, started a 3hour print will see what is going to happen.
@Achi. Have you had this issue again?
@dfos nope printed like 40 hours since then no problem so far. didnt change anything btw i printed two 3 hour prints without filament after the errors and everything was fine.
