4. Product Overview
The Genmitsu 3020-PRO Ultra is a high-performance CNC router designed for precision machining. The Kaba Fold CNC Enclosure provides a clean and quiet working environment.
4.1 Key Features of the 3020-PRO Ultra CNC Machine
- 710W Spindle: The upgraded spindle features a 1/8” ER11 collet and an adjustable speed range of 6500-30000 RPM with 6-speed settings. It provides constant torque control for consistent performance across various materials like solid wood, metal, acrylic, carbon fiber, and soft titanium.
- All-Metal Construction: Built with solid all-metal components, the 3020-PRO Ultra ensures exceptional stability and precise performance. The X-axis features dual linear rails and a lead screw, while the Z-axis uses 10mm and the Y-axis 12mm polished rods with T8 trapezoidal lead screws. Enclosed mold materials and a reinforced X-axis backplate further enhance rigidity.
- Upgraded XYZ-Axis Stepper Motors: Equipped with powerful 60mm stepper motors, delivering an impressive 7.3 Nm of torque, enabling deeper cuts.
- Unmatched Cutting Power: Capable of achieving deeper cuts in aluminum, up to 1.5mm in a single pass.
- Versatile Compatibility: Includes a Φ65mm spindle holder and a Φ52mm adapter, allowing easy switching between different spindles and laser modules. Also compatible with Φ69mm spindle brackets.
- Mainboard Fan and Wireless Control Cable: Features a mainboard fan for cooling and a wireless control cable for enhanced connectivity.

5. Setup
Follow these steps for initial assembly and setup of your CNC machine and enclosure.
5.1 CNC Machine Assembly
- Unpack all components and verify against the package contents list.
- Assemble the frame components according to the included assembly diagrams. Ensure all screws are tightened securely.
- Install the X, Y, and Z-axis assemblies, ensuring smooth movement along all axes.
- Mount the 710W spindle into its holder and secure it.
- Connect all motor cables, limit switches, and the spindle cable to the control board. Refer to the wiring diagram for correct connections.
- Connect the power adapter and USB cable to the control board.
5.2 Kaba Fold CNC Enclosure Setup
- Unfold the enclosure and ensure all panels are correctly aligned.
- Place the assembled CNC machine inside the enclosure.
- Secure any flaps or fasteners to fully enclose the machine.
- Ensure cables can pass through designated openings without being pinched.
6. Operating Instructions
This section outlines the basic steps for operating your Genmitsu 3020-PRO Ultra CNC machine.
6.1 Software Installation and Configuration
- Install the recommended CNC control software (e.g., Candle, UGS) on your computer.
- Install the necessary USB drivers for your control board.
- Configure the software settings according to the machine's specifications (e.g., GRBL settings, baud rate).
6.2 Preparing for a Job
- Design your workpiece using CAD/CAM software and generate the G-code.
- Securely mount your material onto the wasteboard using clamps or other fixtures.
- Insert the appropriate end mill into the ER11 collet and tighten it firmly.
- Connect your computer to the CNC machine via USB.
- Open the CNC control software and establish a connection to the machine.
6.3 Setting Workpiece Zero and Running the Job
- Manually or automatically home the machine if equipped with limit switches.
- Jog the spindle to the desired X, Y, and Z zero positions on your workpiece.
- Set the workpiece zero in the CNC control software.
- Load your G-code file into the software.
- Ensure the enclosure is closed and all safety precautions are observed.
- Start the job. Monitor the machining process closely.
- Upon completion, allow the spindle to stop completely before removing the workpiece.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your CNC machine.
- Cleaning: Regularly clean dust and debris from the machine, especially from lead screws, linear rails, and the spindle. Use compressed air or a soft brush.
- Lubrication: Apply a thin layer of appropriate lubricant to the lead screws and linear rails periodically to ensure smooth movement.
- Tightness Check: Periodically check all screws and fasteners for tightness. Retighten as necessary.
- Collet Maintenance: Clean the ER11 collet and collet nut regularly to prevent buildup that could affect tool concentricity.
- Enclosure Cleaning: Wipe down the Kaba Fold Enclosure with a damp cloth to remove dust and maintain visibility through the windows.
8. Troubleshooting
