• Stepper Motors: Drive the movement along the X, Y, and Z axes.
• Aluminum Profile Frame: Provides the structural integrity of the machine.
• Linear Guides: Ensure smooth and precise movement of the gantry and spindle.
• T8 Screws: Lead screws for precise linear motion.
• Control Panel: Houses the GRBL control board and connections.
• Work Table: The surface where the material to be engraved is placed.

4. Setup and Assembly

The TWOTREES DIY CNC 3018S Pro Engraver requires assembly. Follow these steps carefully.

1. Unpack Components: Carefully remove all parts from the packaging and verify against the parts list.
2. Assemble Base Frame: Connect the aluminum profiles to form the base of the machine. Ensure all screws are tightened securely.
3. Install Linear Guides and Lead Screws: Attach the linear guides and T8 lead screws to the frame, ensuring they are parallel and move freely.
4. Mount Stepper Motors: Securely attach the stepper motors to their designated positions on the X, Y, and Z axes.
5. Assemble Gantry: Construct the gantry (X-axis assembly) and attach the spindle mount.
6. Install Spindle: Carefully insert the spindle motor into its mount.
7. Connect Wiring: Connect all stepper motor wires, limit switch wires (if applicable), and spindle power wires to the GRBL control board. Refer to the wiring diagram provided in the separate assembly guide for detailed connections.
8. Secure Work Table: Attach the work table to the base frame.
9. Initial Power-Up: Connect the power adapter. The GRBL control board should power on.
10. Software Setup: Install the necessary GRBL control software (e.g., Candle, UGS) on your computer and connect the CNC machine via USB. Configure the software according to the provided software guide.

5. Operating Instructions

Once assembled and software configured, you can begin operating your CNC engraver.

1. Prepare Material: Securely fasten your material (e.g., wood, acrylic, PCB) to the work table using clamps or double-sided tape.
2. Install Engraving Bit: Select the appropriate engraving bit for your material and task. Insert it into the spindle collet and tighten securely.
3. Set Origin (Zero Point): Using the control software, manually move the spindle to the desired starting point (X0, Y0, Z0) on your material. Set this as the machine's origin.
4. Load G-code: Load your prepared G-code file into the control software.
5. Start Engraving/Cutting: Initiate the job from the software. Monitor the process closely.
6. Emergency Stop: Be prepared to press the emergency stop button or disconnect power if any issues arise during operation.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your CNC machine.

• Cleaning: After each use, clean dust and debris from the work area, lead screws, and linear guides using a brush or vacuum.
• Lubrication: Periodically apply a thin layer of light machine oil or grease to the lead screws and linear guides to ensure smooth movement.
• Check Connections: Regularly inspect all electrical connections and mechanical fasteners to ensure they are secure.
• Spindle Care: Keep the spindle clean and free of dust. Do not overtighten collets.
• Bit Sharpening/Replacement: Replace or sharpen dull engraving bits for best results and to prevent strain on the spindle motor.
