4. Operating Instructions
Operating your Genmitsu 3020-PRO MAX V2 involves preparing your design, setting up the material, and initiating the carving process.
4.1 Software and Connectivity
- The machine is based on open-source Grbl V1.1.
- Connect the machine to your computer via USB. Drivers and software are typically provided on an included USB stick.
- Utilize compatible CNC control software (e.g., Candle, Easel) to send G-code to the machine.
- The upgraded offline controller allows for operation without a direct computer connection.
4.2 Material Preparation and Carving
- Design Creation: Create your carving design using CAD/CAM software and generate the appropriate G-code.
- Material Securing: Secure your material firmly to the spoilboard using clamps. The integrated measurement scale assists with precise positioning.
- Tool Installation: Install the correct carving bit into the spindle.
- Zeroing: Use the photoelectric Z-probe to accurately set the Z-axis zero point. Manually adjust X and Y axes as needed.
- Initiate Carving: Load the G-code file into your control software or offline controller and begin the carving process.
Always ensure proper ventilation and wear appropriate safety gear, including eye protection, during operation.
5. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your CNC router.
- Cleaning: After each use, clean the machine thoroughly to remove dust, chips, and debris. Pay special attention to the lead screws, guide rails, and spindle area.
- Lubrication: Periodically lubricate the lead screws and linear bearings according to the manufacturer's recommendations to ensure smooth movement.
- Inspection: Regularly inspect all mechanical and electrical connections for looseness or damage. Tighten any loose fasteners.
- Spindle Care: Keep the spindle clean and free of obstructions. Ensure proper cooling during extended operations.
- Spoilboard: Consider using a sacrificial spoilboard (e.g., MDF) on top of the aluminum platform to protect it from damage during through-cuts.
6. Troubleshooting
This section addresses common issues you might encounter and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine not responding to commands. | Loose connections, software not connected, emergency stop engaged. | Check all cables, ensure software is properly connected to the machine, disengage emergency stop button. |
| Motor stalling or losing steps. | Cutting too deep/fast, dull bit, material not secured. | Reduce cutting depth or feed rate, replace bit, ensure material is firmly clamped. |
| Inaccurate carving results. | Loose belts/couplings, incorrect zeroing, machine not level. | Check and tighten belts/couplings, re-zero axes carefully, ensure machine is on a stable, level surface. |
| Spindle not rotating. | Power issue, loose spindle connection, faulty spindle. | Verify power supply to spindle, check spindle wiring, contact support if spindle is faulty. |
If you encounter issues not listed here or require further assistance, please contact Genmitsu customer support.
