1. Preparation: A Good Start Is Half the Battle

Before plugging anything in, there are a few important preparatory steps to ensure your machine runs safely and stably.

• Unboxing and Assembly Check: Carefully inspect all components in the package and assemble the machine correctly according to the instruction manual (usually included) or online tutorials (e.g., "Lunyee 3018 Pro Max Assembly" on YouTube). Make sure all screws are tightened and the guide rails move smoothly.
• Workspace Preparation: Choose a stable, sturdy workbench for your CNC router. Since the engraving process produces dust and noise, it's advisable to operate in a well-ventilated and easy-to-clean area. Prepare a vacuum cleaner or cleaning tools to promptly clear debris.
• Safety First: Wearing safety glasses is a must! Debris can fly during engraving, so eye protection is crucial. Also, know the location of your machine's emergency stop button for any unforeseen circumstances.
• Tools and Consumables:
  • Engraving Bits: Your Lunyee 3018 Pro Max usually comes with some entry-level engraving bits, such as V-bits and flat-end mills. Understand their uses; V-bits are good for detailed lines, while flat-end mills are suitable for larger area engraving and material removal.
  • Engraving Material: For your first project, choose softer, easy-to-work materials like wood (e.g., basswood or pine) or acrylic sheets. They are easy to cut, allowing you to see results faster.
  • Clamps: Used to secure the material and prevent it from moving during engraving. The machine usually comes with clamps, or you can use double-sided tape or vice clamps.
  • Computer and Software: Have a computer with a USB connection ready.

2. Software Setup: The "Brain" of CNC Engraving

The Lunyee 3018 Pro Max typically supports various CNC control software. The most common entry-level choices are Candle (GRBLControl) or UGS (Universal Gcode Sender).

• Install Drivers and Software: Follow the machine's instructions to install the necessary USB drivers and CNC control software.
• Connect the Machine: Connect the router to your computer via a USB cable. Open the control software, select the correct COM port, and set the Baud Rate (usually 115200). Once successfully connected, you should see the machine's coordinate information in the software interface.
• Familiarize Yourself with the Software Interface:
  • Manual Control: Try using the direction keys (X, Y, Z axes) on the software interface to manually move the spindle, familiarizing yourself with the machine's movement direction and range.
  • Homing: Many machines support an auto-homing function, moving the spindle to a preset origin. If your machine doesn't have this, you'll need to manually set the Work Zero.
  • Spindle Control: Understand how to turn the spindle (the rotating part with the engraving bit) on and off.

3. Design Your First Project: Start Simple

For your first project, we highly recommend starting with simple text or graphics.

• Design Software: You can use the following software for designing:
  • Inkscape (Free): Powerful vector graphics software, suitable for designing lines and text.
  • Vectric VCarve Desktop / Aspire (Paid): Professional-grade CNC design software with powerful features but a steeper learning curve.
  • Fusion 360 (Free/Paid): Comprehensive CAD/CAM software for 3D design and toolpath generation.
• Generate G-code: After designing, you need to convert your design into instructions the machine can understand, known as G-code. This is done through CAM (Computer-Aided Manufacturing) software.
  • Select Tool: In the CAM software, select the type and size of the engraving bit you will use.
  • Set Cutting Parameters: This is a crucial step! It includes Feed Rate (how fast the tool moves), Spindle Speed, and Depth of Cut. For your first project, start with conservative parameters, for example:
    • Wood/Acrylic: Feed Rate 500-1000 mm/min, Spindle Speed 8000-10000 RPM, Depth of Cut 0.5-1mm per pass.
    • Note: These are just suggested values; actual parameters need to be adjusted based on your material, bit type, and machine performance.
  • Generate Toolpaths: The software will calculate the tool's movement path based on your design and parameters, and then generate the G-code file (usually ending in .nc, .gcode, or .txt).

4. Begin Your First Engraving!

The exciting moment has arrived!

• Secure Material: Securely fasten your engraving material to the workbench, ensuring it won't move during the engraving process.
• Install Bit: Insert the appropriate engraving bit into the spindle collet and tighten the screws, making sure the bit is firmly secured.
• Set Work Zero:
  • Manually move the spindle to your desired engraving starting point (usually the bottom-left corner or center of the material).
  • In the CNC control software, zero out the X, Y, and Z axis coordinates at the current position. Zeroing the Z-axis is especially important to ensure the tip of the bit just touches the material surface. You can use a piece of paper (e.g., printer paper) as a shim; when the bit touches the paper and it can no longer move freely, note the Z-axis reading and set it as the new Z zero (often, software has an auto-probe function for Z-axis zeroing; if not, you'll need to do it manually).
• Load G-code: Load the G-code file you previously generated into the control software.
• Run Program: After confirming all settings are correct, click the "Start" or "Run" button. Closely observe the machine's operation and be ready to press the emergency stop button at any time.
• Monitor and Adjust: Watch the engraving process to ensure the bit is cutting properly. If you hear unusual noises, see smoke, or notice poor cutting, immediately stop the machine, check, and adjust your parameters.

5. Post-Processing and Cleaning: Perfecting Your Work

• Clean Debris: After engraving, turn off the spindle and use a vacuum cleaner or brush to clean debris from the machine and workspace.
• Remove Project: Carefully remove your first engraved piece.
• Finishing and Sanding: If needed, sand, clean, or paint your piece to make it even more perfect.
