Specifikace

The Mellow WS7040 is a compact and powerful centrifugal blower. Key specifications are detailed below:

Obsah balení

Balíček obsahuje následující položky:

• 1 x WS7040 Blower Fan
• 1 x Driver Board (pre-connected or included for installation)

Nastavení a instalace

The WS7040 blower fan comes with a driver board and supports two primary control methods:

Method 1: Potentiometer Knob Control

For direct speed control using the included potentiometer knob:

1. Ensure the driver board is connected to the fan.
2. Connect the driver board directly to a 24V DC power supply.
3. Use the potentiometer knob to adjust the fan speed.

Method 2: Motherboard or Raspberry Pi Control

To control the fan speed using a 3D printer motherboard or Raspberry Pi:

1. Remove the potentiometer from the driver board.
2. Connect the signal pin of the driver board to a 5V or 3.3V pin on your motherboard or Raspberry Pi.
3. Connect the GND pin of the driver board to the GND of your motherboard or Raspberry Pi.
4. Ensure your firmware is configured correctly for PWM fan control.

Návod k obsluze

Once installed, the fan can be operated via the potentiometer or through your 3D printer's control system. Below are common firmware configurations:

Firmware Configuration Examples:

Marlin Firmware:

To enable software PWM control for the fan in Marlin, modify your Configuration_adv.h file:

• Umožnit FAN_SOFT_PWM.
• Soubor SOFT_PWM_SCALE na 5.

Duetboard Firmware:

For Duetboards, fan control typically involves configuring the fan output in your config.g file using M950 and M106 commands. Ensure the fan is assigned to a PWM-capable pin and configured for the correct frequency and inversion if necessary. Refer to the Duet3D documentation for detailed fan configuration specific to your Duet board version.

Klipper Firmware:

For Klipper, add a fan section to your printer configuration file (např, printer.cfg):

[fan]
pin: host:gpio26
hardware_pwm: False
cycle_time: 0.005

Upravit pin: host:gpio26 to match the actual GPIO pin connected on your Raspberry Pi or host device.

Údržba

To ensure optimal performance and longevity of your Mellow WS7040 blower fan, follow these maintenance guidelines:

• Čištění: Periodically inspect the fan's intake and outlet for dust, debris, or filament strands. Gently clean with compressed air or a soft brush to prevent blockages and maintain airflow efficiency.
• Provozní prostředí: Operate the fan within its specified temperature range of -20°C to +60°C. Avoid environments with high humidity or condensation, as this can damage internal components.
• Životnost ložiska: The NMB ball bearings are designed for a long service life (up to 10,000 hours MTTF at 25°C). Avoid excessive mechanical stress or vibrations that could shorten bearing life.
• Napájení: Ensure a stable 24V DC power supply is used. Fluctuations or incorrect voltage can affect performance and lifespan.

Odstraňování problémů

If you encounter issues with your WS7040 blower fan, consider the following troubleshooting steps:

• Ventilátor se netočí:
  • Check power connections to the driver board and ensure a stable 24V DC supply.
  • Verify all wiring connections are secure and correct according to the installation diagram.
  • If using potentiometer control, ensure the potentiometer is not set to minimum speed.
  • If using motherboard/Raspberry Pi control, check your firmware configuration and ensure the control signal pin is correctly connected and outputting a PWM signal.
• Reduced Airflow/Noise:
  • Inspect the fan blades and housing for any obstructions (dust, debris). Clean as necessary.
  • Ensure the fan is mounted securely and not vibrating excessively.
  • Check for any damage to the fan blades or housing.
• Nekonzistentní rychlost:
  • If using potentiometer control, check the potentiometer for loose connections or damage.
  • If using motherboard/Raspberry Pi control, verify the stability of the PWM signal from your controller.

If problems persist after attempting these steps, please contact Mellow 3D Official Store support for further assistance.

Tipy pro uživatele

• Driver Board Included: The WS7040 blower fan package includes the necessary driver board, simplifying installation and control.
• Všestranné ovládání: The fan can be controlled either directly via the included potentiometer for manual speed adjustment or integrated into a 3D printer's control system (e.g., Marlin, Duet, Klipper) for automated control.
• Kompatibilita: While designed for 3D printers like VzBoT and HevORT, the fan's 24V DC input and flexible control options make it adaptable to various projects requiring high-pressure airflow.
