固件设置¶

Klipper¶

将风扇端口引脚插入下面的引脚部分，并复制到 “printer.cfg” 文件中：

[fan]

pin: # Output pin controlling the fan. This parameter must be provided.

max_power: 0.8 

# This should be set to 0.8 on most motherboards to give full range of control to your slicer. 

# Anything above 80% duty cycle will be full power on this particular brushless driver.

# To fine-tune the max_power parameter for your particular motherboard, set max_power to 1.0, go into the Klipper dashboard, and increase fan speed 1% at a time until the actual fan speed stops increasing as you increase the fan speed. Divide the fan speed at this point by 100 and enter it into the max_power parameter.

# This parameter defines the maximum power (expressed as a value from 0.0 to 1.0) that the pin may be set to. 

# The value 1.0 allows the pin to be set fully enabled for extended periods, while a value of 0.5 would allow the pin to be enabled for no more than half the time. 

# This setting may be used to limit the total power output (over extended periods) to the fan. 

# If this value is less than 1.0, then fan speed requests will be scaled between zero and max_power (for example, if max_power is 0.9 and a fan speed of 80% is requested, then the fan power will be set to 72%).

shutdown_speed: 0 

# The desired fan speed (expressed as a value from 0.0 to 1.0) if 

# The microcontroller software enters an error state. 

# The default is 0.

cycle_time: 0.005 

# The amount of time (in seconds) for each PWM power cycle to the fan. 

# It is recommended this be 10 milliseconds or greater when using software-based PWM. 

# The default is 0.010 seconds.

hardware_pwm: False 

# Enable this to use hardware PWM instead of software PWM. 

# Most fans do not work well with hardware PWM, so it is not recommended to enable this unless there is an electrical requirement to switch at very high speeds. 

# When using hardware PWM, the actual cycle time is constrained by the implementation and may be significantly different than the requested cycle_time. 

# The default is False.

kick_start_time: 0.100 

# Time (in seconds) to run the fan at full speed when either first enabling or increasing it by more than 50% (helps get the fan spinning). 

# The default is 0.100 seconds.

off_below: 0.1 

# The blower will not spin with the included brushless driver when the duty cycle is below 8%. When scaled with Max_power at 0.8, the off_below parameter should be set to 0.1. 

# To calibrate this setting, gradually lower the fan speed to determine the lowest input speed that reliably drives the fan without stalls. 

# Set off_below to the duty cycle corresponding to this value (for example, 8% -> 0.08/Max_power -> 0.08/0.8 -> 0.1) or slightly higher. 

# This parameter is the minimum input speed that will power the fan (expressed as a value from 0.0 to 1.0). 

# When a speed lower than off_below is requested, the fan will instead be turned off. 

# This setting may be used to prevent fan stalls and to ensure effective kick starts. 

# To calibrate this setting, start with off_below set to 0.0 and the fan spinning. 

# Gradually lower the fan speed to determine the lowest input speed that reliably drives the fan without stalls. 

# Set off_below to the duty cycle corresponding to this value (for example, 12% -> 0.12) or slightly higher.

#Tachometer_pin:

# Tachometer input pin for monitoring fan speed. A pullup is generally required. 

# This parameter is optional.

#Tachometer_ppr: 1

# When tachometer_pin is specified, this is the number of pulses per revolution of the tachometer signal.

#Tachometer_poll_interval: 0.0005

# When tachometer_pin is specified, this is the polling period of the tachometer pin, in seconds. 

# The default is 0.0015, which is fast enough for fans below 10,000 RPM at 2 PPR. 

# This must be smaller than 30/(tachometer_ppr*rpm), with some margin, where rpm is the 

# maximum speed (in RPM) of the fan.

打印件说明¶

首先，打印"Stealthburner Parts"文件夹中的所有模型。您还需要以下额外部件来完成热端组装:

1x BTT KNOMI V2.0；1x 15mm CPAP管；2x扎带。

接下来，根据您偏好的配置，从"Exhaust parts"文件夹中选择一个，并打印该文件夹内的所有模型。您可以从以下4种配置中选择:

1、Voron 排气罩的重新设计版本，集成了 SFS V2.0 模块，使用了随附的空气过滤器，不需要60mm排气风扇。

这是推荐配置，因为它完全封闭了风扇，将噪音降至最低。

*此设计是基于 Printables 上 @MichalKelnar_1267496 的设计改编而成。

对于此配置，您将需要以下额外部件：

1x BIGTREETECH SFS V2.0 模块

2、Voron-Exhaust-UTK-without-fan: 修改后的 Voron design V2.4 排气罩，不带60mm排气风扇。这是非 SFS 用户的推荐配置，因为它完全封闭了风扇，将噪音降至最低。

对于此配置，不需要额外部件。

3、Voron-Exhaust-UTK-SFS-with-fan: 这是 Voron 排气罩的重新设计版本，集成了 SFS V2.0 模块和一个 60mm 排气风扇。由于 CPAP 风扇位置的原因，需要一个强力的 60mm 风扇来保持打印机机壳内的负压；请注意，这将产生较高的噪音，因为风扇没有被封闭。
