[Suggestion] Control your RPI fan hat with macros

[thiagolocatelli]

You can control the fan speed on your fan hat by using macros and I2C. Just install the gcode shell command klipper plugin (manually or via Kiuah), enable I2C via raspi-config and then use there

[gcode_shell_command rpi_fan_50]
command: i2cset -y 1 0x01a 0x32
timeout: 30.
verbose: True

[gcode_shell_command rpi_fan_25]
command: i2cset -y 1 0x01a 0x19
timeout: 30.
verbose: True   

[gcode_macro rpi_fan_50]
gcode:
    RUN_SHELL_COMMAND CMD=rpi_fan_50

[gcode_macro rpi_fan_25]
gcode:
    RUN_SHELL_COMMAND CMD=rpi_fan_25
