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

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.
