Hi,

I've connected fan on PG19 pin and Klipper doesn't recognize them. Do you have a config to make it work?

error mainsail : Pin 'PG19' is not a valid pin name on mcu 'mcu'

actually I've bypass with one pin on my board but I want to use PG19 pin on BTT PI

[temperature_fan raspberry_pi] pin: PB6 kick_start_time: 0.8

shutdown_speed: 0

off_below: 0.1 max_power: 1.0

fan_speed: 0.6

sensor_type: temperature_host control: pid min_temp: -40 max_temp: 85

pid_kp: 1.0 pid_ki: 0.5 pid_kd: 2.0 min_speed: 0.1 max_speed: 0.6 target_temp: 38

If i create and another MCU like this :

[mcu host] serial: /tmp/klipper_host_mcu

And define :

[temperature_fan raspberry_pi] pin: host:PG19

I've got message like this : Pin 'PG19' is not a valid pin name on mcu 'host'

SOLVED !

PG19 is definitely a GPIO pin. It may not be on the 40 pin GPIO header but any input / output pin on the BTT Pi and CB1 is GPIO.

The formula to convert from PG19 to GPIO is:

[(PG - PA)*32] + {Pin Number}

Where PA = 1, PB =2….so PG = 7

So [(7-1)*32] + 19 = 211

Try using GPIO211

The BTT documentation on this is rubbish and lacking.
