1. SSH into yourRaspberryPiand edit yourprinter.cfgfile usingnano.

2. Remove any old thermistor configuration under [extruder]. (sensor_type, sensor_pin, etc.)

3. Under [extruder] add these lines:

   sensor_type: MAX31865
sensor_pin: PD11 # I pulg into Spider E4-MOT socket, `cs` pin is the sensor pin
spi_speed: 4000000
spi_software_sclk_pin: PE12
spi_software_mosi_pin: PE14
spi_software_miso_pin: PE13
rtd_nominal_r: 100
rtd_reference_r: 430
rtd_num_of_wires: 2

4. If you are in EU or any 50 Hz country add this line:rtd_use_50Hz_filter: True

5. Save your changes by typing CTRL+X, Y, [ENTER]. Send FIRMWARE_RESTART from the console in Octoprint and test! It should work.

6. Run PID tuning. PT100 readings will be different from your previous thermistor. For the best thermal accuracy, follow this to PID tune:

   1. Heat your bed to 100C.
2. Move your hothend to the center and 5-10 mm above bed
3. Set fans to 25%: "M106 S64"
4. Run: "PID_CALIBRATE HEATER=extruder TARGET=245"
5. This will run for a few minutes. When finished, save with: "SAVE_CONFIG"
