Makerbase MKS 3MOS Plug-in 3 FANs Expansion Module

1. Introducció

The MKS 3MOS is a fan-connected module designed to expand the fan control capabilities of compatible 3D printer motherboards. This module integrates three MOS control outputs, allowing for independent control of up to three fans. Its pins and dimensions are compatible with standard pluggable motor drive slots, enabling direct connection and simple configuration via the pin file.

The MKS 3MOS module is suitable for motherboards with more than 5 axis motor drive slots, including but not limited to MKS Robin Nano, MKS Gen-I, MKS sgen-l, Monster8, and MKS TinyBee.

2. Configuració i instal·lació

The MKS 3MOS module is designed for easy plug-and-play installation into compatible motor driver slots on your 3D printer motherboard. Ensure your motherboard is powered off before installation.

2.1 Instal·lació física

Identify an available motor drive slot on your motherboard. Carefully align the pins of the MKS 3MOS module with the corresponding header on the motherboard and gently press down until it is securely seated. The module's orientation is crucial; ensure the fan connectors face outwards or as indicated by your motherboard's layout.

2.2 Cablejat

The MKS 3MOS module provides three controllable fan output ports, labeled FAN1, FAN2, and FAN3. Connect your 3D printer fans to these ports. Ensure correct polarity (+ and -) when connecting fans.

2.3 Firmware Settings

To enable and control the fans connected to the MKS 3MOS module, you will need to modify your 3D printer's firmware (e.g., Marlin). The following example shows how to configure the pin file if your board's pins have FAN1_PIN and you need to start from FAN2_PIN, assuming connection to the E1 axis:

                
// If connect to E1 axis. If board's pins has FAN1_PIN, you need to start from FAN2_PIN
#define FAN1_PIN E1_ENABLE_PIN
#define FAN2_PIN E1_STEP_PIN
#define FAN3_PIN E1_DIR_PIN
                
            

Refer to your specific motherboard's documentation and firmware configuration guides for detailed instructions on pin assignments and fan control setup.

3. Funcionament

Once the MKS 3MOS module is installed and configured in your firmware, you can control the connected fans using G-code commands.

3.1 Command Control

Use the following G-code commands to control the fans:

• **To open a fan:** M106 P* S255
• **To close a fan:** M106 P* S0

On * represents the fan number (1, 2, or 3) corresponding to FAN1, FAN2, or FAN3 on the module. S255 sets the fan to full speed (255 being the maximum PWM value), and S0 apaga el ventilador.

Nota: El M107 command for closing fans is generally not recommended for use with this module.

4. Manteniment

The MKS 3MOS module is a robust electronic component and generally requires minimal maintenance. To ensure optimal performance and longevity:

• Keep the module clean and free from dust and debris. Use compressed air or a soft brush for cleaning.
• Ensure proper airflow around the module and motherboard to prevent overheating.
• Regularly check fan connections to ensure they are secure.
• Avoid exposing the module to excessive moisture or extreme temperatures.

5. Solució De Problemes

If you encounter issues with your MKS 3MOS module, consider the following basic troubleshooting steps:

• **Fans not spinning:**
  • Verify that the fans are correctly wired to the module with the correct polarity.
  • Check your firmware configuration to ensure the fan pins are correctly defined and enabled.
  • Confirm that the G-code commands sent are correct (e.g., M106 P1 S255 for FAN1).
  • Test the fans directly to ensure they are functional.
• **Module not recognized:**
  • Ensure the module is fully seated in the motherboard's motor drive slot.
  • Verify that your motherboard is compatible with the MKS 3MOS module.
• **Intermittent fan operation:**
  • Check for loose connections on both the module and the fan cables.
  • Inspect the module for any visible damage or cold solder joints.
