3.2 App Installation and Initial Pairing
- Download the App: Search for the official Genmitsu app on your mobile device's app store (iOS or Android).
- Install and Open: Install the app and launch it.
- Connect to Wi-Fi: Ensure your mobile device is connected to a 2.4G Wi-Fi network. The GGW-USB module only supports 2.4G Wi-Fi.
- Pair with Module: Follow the in-app instructions to discover and pair with your GGW-USB Wi-Fi module. This typically involves selecting the module from a list of available devices.
4. Operating Instructions
4.1 G-Code File Transmission
- Obtain G-Code: Download G-code files from online resources or create them using your preferred CAM software. Save these files to your mobile device.
- Upload via App: Within the Genmitsu app, navigate to the file management section. Select the G-code file you wish to send to your CNC machine.
- Wireless Transfer: Initiate the wireless transfer. The app will send the G-code file to the GGW-USB module, which then relays it to the CNC machine for execution.

4.2 Remote Control and Monitoring
- Jog Control: Use the app's interface to manually move the CNC axes (X, Y, Z) for precise positioning. Adjust step sizes (e.g., 0.1mm, 1mm, 10mm) and feed rates as needed.
- Spindle Control: Start, stop, and adjust the spindle speed directly from the app.
- Homing and Zeroing: Utilize the app to perform homing cycles and set workpiece zero points (X0, Y0, Z0) for your projects.
- Real-time Monitoring: The app displays real-time information about the CNC machine's status, including current coordinates, progress, and any alerts.
- Macro Buttons: Configure custom macro buttons within the app for frequently used commands or sequences.

5. Maintenance
To ensure the longevity and optimal performance of your GGW-USB Wireless Wi-Fi Module, follow these maintenance guidelines:
- Keep Clean: Regularly wipe the module with a dry, soft cloth to remove dust and debris. Avoid using liquid cleaners directly on the module.
- Protect from Environment: Keep the module away from excessive moisture, extreme temperatures, and direct sunlight. Ensure it is not exposed to metal shavings or other conductive materials common in CNC environments.
- Secure Connections: Periodically check that all cable connections (USB, DC) are secure and free from damage.
- Software Updates: Check the Genmitsu app regularly for firmware updates for the module to ensure you have the latest features and bug fixes.
6. Troubleshooting
If you encounter issues with your GGW-USB Wireless Wi-Fi Module, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not powering on | Loose power connection; CNC machine not powered on. | Ensure USB and/or Dual DC cables are securely connected. Verify the CNC machine is powered on. |
| App cannot find the module | Mobile device not on 2.4G Wi-Fi; module not powered; module out of range; incorrect app settings. | Connect your mobile device to a 2.4G Wi-Fi network. Ensure the module is powered. Move closer to the module. Check app's connection settings. |
| G-code transfer fails or is slow | Weak Wi-Fi signal; interference; large file size. | Improve Wi-Fi signal strength. Reduce interference from other devices. For very large files, consider breaking them into smaller segments if possible. |
| App is unresponsive or crashes | Outdated app version; mobile device resource issues; temporary software glitch. | Update the Genmitsu app to the latest version. Restart the app and your mobile device. Clear app cache if necessary. |
| CNC machine does not respond to app commands | Module not properly connected to CNC; CNC machine in an error state; incorrect Grbl settings. | Verify the USB connection between the module and CNC. Check the CNC's display or status indicators for errors. Consult your CNC machine's manual for Grbl settings. |
