2. Software Installation and Connection
The machine operates with open-source GRBL compatible software. Popular choices include Candle and Universal Gcode Sender (UGS). A 3-month Carveco Maker Subscription is included to assist with design and G-code generation. Install your preferred software on your computer and connect the CNC machine via USB.
3. Initial Calibration and Homing
After assembly and software setup, perform initial calibration and homing procedures. The machine is equipped with XYZ axis limit switches for accurate homing. Use the Z-probe for precise Z-axis height setting before starting any carving job.

Operating Instructions
1. Preparing Your Project
Design your project using CAD/CAM software (e.g., Carveco Maker) and generate the G-code. Ensure your G-code is compatible with GRBL. Securely clamp your material to the machine's work area (400 x 300 x 110mm). The machine's rigid C-beam structure and dual Y-axis screw drive provide stability for various materials.

2. Loading G-Code and Starting the Job
Load the generated G-code into your control software. Perform a dry run (air cut) to verify the tool path before actual cutting. Use the integrated control box buttons for easy access to functions like Pause, Resume, and Reset. The intuitive speed control wheel allows for on-the-fly adjustments.

3. Material Compatibility
The PROVerXL 4030 is capable of working with a wide range of materials, including:
- Wood (softwoods, hardwoods)
- MDF
- Plastics (Acrylic, PVC, ABS)
- Foams
- Vinyl
- Aluminum
Always use appropriate bits and cutting parameters for each material to achieve optimal results and prolong tool life.
Maintenance
Regular maintenance ensures the longevity and precision of your Genmitsu PROVerXL 4030.
- Cleaning: After each use, clear all dust, chips, and debris from the machine, especially from the leadscrews, rails, and stepper motors. A vacuum cleaner with a brush attachment is recommended.
- Lubrication: Periodically apply a thin layer of light machine oil or grease to the leadscrews and linear rails to ensure smooth movement and prevent wear.
- Component Inspection: Regularly check all bolts, nuts, and connections for tightness. Ensure the belts are properly tensioned (if applicable) and that the stepper motors are free from obstruction. Inspect the Z-probe and limit switches for proper function.
- Spindle Care: Keep the spindle clean and free of debris. If upgrading to a Dewalt DWP611, follow its specific maintenance guidelines.

Troubleshooting
This section addresses common issues you might encounter with your PROVerXL 4030. For more complex problems, refer to the official Genmitsu support resources.
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine not responding / erratic movement | Loose wiring, software communication issue, motor fault, incorrect GRBL settings. | Check all cable connections. Ensure only one control interface (e.g., UGS or offline controller) is connected at a time. Verify GRBL settings match recommended values. Inspect stepper motors for damage. |
| Spindle not starting or stopping correctly | Power supply issue, wiring problem, spindle motor fault. | Check spindle power connections. Ensure the spindle switch on the control box is in the correct position. If the spindle requires a manual spin to start, it may indicate a motor issue requiring replacement. |
| Poor carving quality / chatter | Loose material clamping, incorrect cutting parameters (feed rate, depth of cut), dull bit, excessive play in axes. | Ensure material is securely clamped. Adjust cutting parameters for the specific material and bit. Replace dull bits. Check for any loose components or excessive play in the gantry or axes. |
| Z-axis homing issues | Z-probe not connected, Z-limit switch malfunction, debris obstructing movement. | Verify Z-probe connection and function. Check Z-limit switch for proper operation and clear any obstructions. |
