MCU / Printerboard:Octopus Pro
I want to use PT100 2 Wire thermistor with MAX31865 on Octopus Pro Board Driver Slot but getting error
Thermocouple Reader Fault
My Klipper Config in Printer.Cfg is as :
[extruder]
step_pin: PC13
dir_pin: PF0
enable_pin: !PF1
microsteps: 32
rotation_distance: 33.500
nozzle_diameter: 0.400

heater_pin: PA3 #H1
sensor_type: MAX31865
sensor_pin: PD3
spi_speed: 4000000
spi_software_sclk_pin: PA5
spi_software_mosi_pin: PA7
spi_software_miso_pin: PA6
rtd_nominal_r: 100
rtd_num_of_wires: 2
rtd_use_50Hz_filter: false

control: pid
pid_Kp: 22.2
pid_Ki: 1.08

I also put jumpers in spi mode on driver slot and the same is working with Marlin firmware but not with Klipper.
