btt pi 一代自带风扇引脚,但是这个引脚号PG19在klipper当中是错误的。
纠正办法:
先在配置文件printer.cfg里面添加pi的mcu
- [mcu host]
- serial: /tmp/klipper_host_mcu
复制代码
然后,再订正pi风扇
在klipper中,引脚号为:gpio211
- [temperature_fan btt_pi]
- pin: host:gpio211
- 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: 0
- max_temp: 85
- #max_delta: 5.0
- pid_kp: 1.0
- pid_ki: 0.5
- pid_kd: 2.0
- min_speed: 0.1
- max_speed: 0.6
- target_temp: 38
