Use temperature sensor data attached to SBC in Klipper

General Discussion

If you check the schematic, you will see that:

  • SD-CS = PA4
  • SD-SCK = PA5
  • SD-MISO = PA6
  • SD-MOSI = PA7

Using this information a basic setting for the PT100 in the extruder would look like:

[extruder]
...
sensor_type: MAX31865
sensor_pin: PA4
spi_speed: 4000000
spi_software_sclk_pin: PA5
spi_software_mosi_pin: PA7
spi_software_miso_pin: PA6
rtd_nominal_r: 100
rtd_reference_r: 430
rtd_num_of_wires: 2
rtd_use_50Hz_filter: True
...

The rtd_* needs to be tuned according to your setup. Check the Klipper Docs for an explanation.
