ADC out of range after hardware upgrade

The issue:

Hi there, so I have recently started to convert my printer into a Voron Stealthburner. I have decided to install can bus header ebb sb2209 + u2c to it. After a long struggle, I have managed to get it to work. Well, more or less- Klipper outputs this error message as of now;

Blockquote
Klipper reports: SHUTDOWN
MCU ‘mcu’ shutdown: ADC out of range
Sensor ‘heater_bed’ temperature -72.505 not in range 0.000:130.000
Sensor ‘extruder’ temperature 370.403 not in range 0.000:300.000
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

My bed is definitely plugged in correctly, and so is the hotend (into the sb 2209). For example, the printer fans work, so does KNOMI and the cr touch (it does flash red, but it might be due to my wiring being incorrect) whilst the hotend & Neo Pixels do
not seem to be recognised at all. Would anyone have an idea why this is happening?

Thanks!

Hello @Zonko !

For the config, you still have the sensor connected to the the board. That includes the hotend heating issue.

[extruder]
step_pin = PB4
dir_pin = PB3
enable_pin = !PC3
microsteps = 16
rotation_distance = 34.406
nozzle_diameter = 0.400
filament_diameter = 1.750
heater_pin = PA1   # <---------------
sensor_type = EPCOS 100K B57560G104F
sensor_pin = PC5
control = pid   # <---------------
pid_kp = 21.527
pid_ki = 1.063
pid_kd = 108.982
min_temp = 0

max_extrude_only_distance = 100.0

You may check the sensor cables for shorts and/or breaks
And also check the other part’s (

) wiring too.
