3. Setup and Assembly
The Genmitsu 3018-PROVer V2 is designed for quick and easy assembly, with many components pre-assembled. Follow the included assembly guide for detailed step-by-step instructions.
3.1 Unpacking and Inspection
Carefully unpack all components and verify against the packing list. Inspect for any shipping damage. Report any discrepancies or damage to Genmitsu support immediately.
3.2 Basic Assembly Steps
Assembly typically involves attaching the gantry to the base, installing the spindle, and connecting the wiring. The upgraded design minimizes complex steps.

3.3 Electrical Connections
Connect the stepper motors, limit switches, and spindle to the control board. Ensure all connections are secure before powering on the machine.

4. Operating Instructions
The 3018-PROVer V2 operates using the GRBL v1.1 firmware and can be controlled via its offline controller or a connected computer.
4.1 Offline Control
The included offline controller allows for direct control of the machine without a computer. It can load G-code files from an SD card, jog the axes, set home positions, and start/pause/stop jobs.
4.2 Software Control (GRBL)
For advanced control and design, connect the machine to a computer running compatible GRBL control software (e.g., Candle, UGS). This allows for real-time monitoring, G-code sending, and more complex operations.
4.3 Spindle Operation
The spindle speed can be adjusted manually or via G-code commands. Ensure the correct collet and bit are installed and tightened before operation.
4.4 Using Extended Ports
- Laser Port: Connect a compatible laser module for engraving and cutting applications.
- Air Assistance Pump Port: Connect an air pump for improved chip evacuation during milling.
- MPG Port: Connect a Manual Pulse Generator for precise manual control of axis movement.
4.5 Firmware Updates
The 3018-PROVer V2 supports firmware updates via an SD card, allowing for future enhancements and bug fixes. Refer to the Genmitsu website for the latest firmware and update instructions.
5. Spoilboard and Extension
The machine comes with a robust aluminum spoilboard and is compatible with a 3040 extension for larger projects.
5.1 Original Aluminum Spoilboard
The one-piece machined and molded aluminum spoilboard provides a flat and stable work surface. It is designed with a grid of threaded holes for easy clamping of workpieces.


5.2 3040 Extension Compatibility
The 3018-PROVer V2 is designed to work seamlessly with the 3018PROVer-V2 Y-Axis Extension Kit, allowing you to expand your work area from 3018 to 3040. This extension uses a new 4mm sheet metal connector design to attach the aluminum spoilboard to the polishing bar, ensuring the Y-axis travel area remains constant.


6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Genmitsu 3018-PROVer V2.
- Cleaning: Regularly clean dust and debris from the lead screws, linear rails, and gantry using a brush or compressed air. Avoid using solvents that may damage plastic components.
- Lubrication: Apply a thin layer of light machine oil or grease to the lead screws and linear rails periodically to ensure smooth movement.
- Tighten Fasteners: Periodically check and tighten all screws and bolts to ensure structural integrity.
- Spindle Care: Keep the spindle clean and free of dust. If the spindle motor becomes excessively hot or noisy, discontinue use and contact support.
- Collet Maintenance: Clean collets regularly to ensure proper grip on bits. Replace worn collets to prevent bit slippage.
