Klipper reports: ERROR

After assembling V-Core 4 500 and configuring electronics using this guide https://os.ratrig.com/docs/installation/ (linked from https://ratrig.dozuki.com/Guide/12.+Electronics/250?lang=en), which went ok (with flashing everything), I try to follow the Commissioning guide (https://docs.ratrig.com/commissioning-guides/v-core-4). So, powered the printer for the very first time, wait couple of minutes, opened the http://ratos.local and got the below 2 errors in Dashboard. All is up-to-date in Update Manager. I'm not very experienced, any idea please?

This was shown one during startup:

Klipper reports: SHUTDOWN

MCU 'mcu' shutdown: ADC out of range

Sensor 'extruder' temperature 3830551.181 not in range 0.000:350.000

This generally occurs when a heater temperature exceeds
its configured min_temp or max_temp.
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

This is shown all the time, I go to Dashboard, Machine, etc.:

Klipper reports: ERROR

Can not update MCU 'mcu' config as it is shutdown
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.

This guide is still in progress, as more detailed instructions on how to prepare all wires will be added in the next few days.

Solution

So, after some days wait, I've received a new replacement Toolboard EBB42 v1.2 from RatRig (thanks a lot!). After replacing, and lot of playing with setup, updates, etc. I finally managed to make it working and the temperature was shown correctly after startup. Somehow I was also missing the Toolboard configuration (not in the instructions, I followed?), and the need to tell where the X/Y stops are connected, etc. After setting all that correctly, it finally all worked from HW and electronics point of view.

Now I try to calibrate the Heightmap, I'm getting quite bad values, like 0.341 range, the front side is up by 0.08 and the back left corner is down by 0.26.
