MCU 'mcu' shutdown: Timer too close on voron 2.4

Hi Eddy thanks for reply.
i ve already read those, going by step
high load: not the case im running 10 to 20%
low free memory: host is clean only linux and klip ram is using only 800mb of 4gigs , hdd has around 100gb free
unstable voltage: is this refered to host or to mcu? host cant have unstable cause its connected to the plug and also has a working battery (laptop) , if we are talking about mcu thats another story , what do you think?
about the remaining i dont know how to filter them to the proper cause.
did you have a chance to take a look to the log?
thanks again
