Setup Instructions

The Genmitsu 3020-PRO Ultra CNC Router features a modular assembly design, allowing for quick and straightforward installation. Most components are pre-assembled, significantly reducing setup time.

1. Unpacking: Carefully remove all components from the packaging. Verify that all parts listed in the packing list are present and undamaged.
2. Base Assembly: The base frame is largely pre-assembled. Ensure all screws are securely tightened.
3. Gantry Installation: Attach the gantry assembly to the base. This typically involves aligning the pre-assembled gantry with the base and securing it with the provided fasteners.
   

   Figure 9: Simplified diagram showing the three main steps for assembly: Base, Gantry, and Spindle attachment, indicating a quick setup process.
4. Spindle Attachment: Mount the 710W spindle to the gantry. Ensure it is securely fastened and properly aligned.
5. Wiring Connections: Connect all necessary cables, including power, motor, and limit switch wires. The machine's integrated design simplifies these connections.
6. Software Installation: Install the necessary control software (e.g., Candle, Universal Gcode Platform) from the provided flash drive or the official Genmitsu website. Ensure you download the latest drivers compatible with your operating system.
7. Initial Calibration: Perform initial calibration steps as outlined in the software's documentation to set up the machine's home position and workspace limits.

Operating Instructions

Operating the Genmitsu 3020-PRO Ultra involves preparing your design, setting up the material, and initiating the carving process.

1. Design Preparation: Create or import your design using CAD/CAM software. Generate the G-code file that the CNC machine will interpret.
2. Material Setup: Securely mount your material onto the work area using the provided clamps. The work area measures 11.8" x 8.1" x 3.1" (300mm x 205mm x 78mm).
