OrcaSlicer use `M106 P2` command to control auxiliary cooling fan.
|
|
|
|
If you are using Klipper, you can define a `M106` macro to control the both normal part cooling fan and auxiliary fan and exhuast fan.
|
|
Below is a reference configuration for Klipper.
|
|
*Note: Don't forget to change the pin name to the actual pin name you are using in the configuration*
|
|
|
|
```
|
|
# instead of using [fan], we define the default part cooling fan with [fan_generic] here
|
|
# this is the default part cooling fan
|
|
[fan_generic fan0]
|
|
pin: PA7
|
|
cycle_time: 0.01
|
|
hardware_pwm: false
|
|
|
|
# this is the auxiliary fan
|
|
# comment out it if you don't have auxiliary fan
|
|
[fan_generic fan2]
|
|
pin: PA8
|
|
cycle_time: 0.01
|
|
hardware_pwm: false
|
|
|
|
# this is the exhaust fan
|
|
# comment out it if you don't have exhaust fan
|
|
[fan_generic fan3]
|
|
pin: PA9
|
|
cycle_time: 0.01
|
|
hardware_pwm: false

[gcode_macro M106]
|
|
gcode:
|
|
{% set fan = 'fan' + (params.P|int if params.P is defined else 0)|string %}
|
|
{% set speed = (params.S|int if params.S is defined else 255) %}
|
|
SET_FAN_SPEED FAN={fan} SPEED={speed}
|
