Currently receiving this error: 'Can not update MCU 'mcu' config as it is shutdown'

How do I remedy this? I'm currently using an elegoo neptune 3 pro;

First change your tags to Klipper as that is. Klipper fault, second send a the Klipper.log, third try a reboot

Replaced heat block and nozzle after catastrophe, klipper now shows MCU error?

Honestly saying, most of you need to learn how to prepare stuff. We add the log rotate feature for a good reason!!! Really no one wants to analyze a 33 MB text file for no reason. You could have done a rotate and the file would have been a few hundred kilo bytes …

#

You have an “broken“ extruder thermistor. That means it is either broken, or has an broken or short wire

#

That is the message of Klipper MCU 'mcu' shutdown: ADC out of range

#

And that is normally also shown in mainsail.
The restart problem is normal after an Error like that a normal restart is not enough you need an fw_restart

Here is one timestamp stats Stats 792125.2: gcodein=0 mcu: mcu_awake=0.001 mcu_task_avg=0.000010 mcu_task_stddev=0.000008 bytes_write=1471 bytes_read=13460 bytes_retransmit=54 bytes_invalid=203 send_seq=179 receive_seq=179 retransmit_seq=2 srtt=0.003 rttvar=0.000 rto=0.025 ready_bytes=0 upcoming_bytes=0 freq=84003610 heater_bed: target=0 temp=22.6 pwm=0.000 raspberry_pi: temp=53.6 mcu_temp: temp=44.4 sysload=0.10 cputime=2.390 memavail=3502660 print_time=0.011 buffer_time=0.000 print_stall=0 extruder: target=0 temp=-42.0 pwm=0.000

You can clearly see that the act temp of your extruder is -42C and I doubt that you live in Sibiria

#

Especially as your bed act is 22.6C 😜
