This document provides installation and operation instructions for VEVOR CNC Engraving Machines, models S3020 and S4040. These machines are designed for engraving tasks, offering a balance of performance and affordability.
Function Description
The VEVOR CNC Engraving Machine is a computer numerical control (CNC) device used for precise engraving and carving on various materials. It operates by translating digital designs into physical movements of a cutting tool (spindle) across X, Y, and Z axes. The machine is controlled via software, allowing users to import G-code and execute engraving operations.
Key functions include:
- Engraving and Carving: Capable of detailed work on different materials.
- Multi-axis Control: Utilizes X, Y, and Z axes for comprehensive movement and depth control.
- Software Integration: Compatible with control software like Candle for design import, machine control, and monitoring.
- Connectivity: Features USB interface for connection to a computer and an optional offline controller for standalone operation.
- Spindle Options: Supports different spindle types (42 Spindle, 300w Spindle for S3020; 9500 RPM/Min for S4040) and laser modules.

Usage Features
The usage of the VEVOR CNC Engraving Machine involves several key steps, from assembly to software operation:
Installation Steps (Model S3020)
- Mounting Control Box: Attach the control box to the gantry frame using M5*6mm screws.
- Mounting Base: Place the gantry onto the base and secure it with M5*20mm screws.
- Interface Diagram: Connect the Z-Motor, Y-Motor, X-Motor, USB, Offline controller, Limit switches, and Z-probe to the control board as indicated. Spindle and Laser connections are also specified.
Installation Steps (Model S4040)
- Mounting Base: Assemble the base structure with the left and right Y-axis components using M5*16 screws.
- Install the Panel: Place the panel on the base, align screw holes, and secure with M5*20mm screws.
- Install the Gantry: Position the gantry frame on the left and right Y-axis and secure with M5*16 screws.
- Mounting Spindle: Place the main shaft (spindle) on the gantry frame and fix it with M5*55 screws.
- Install Y-axis Fastener: Attach two tow chain fasteners to the Y-axis using M4*6 screws.
- Install X-axis Fastener: Attach the X-axis tow chain fastener using M4*6 screws.
- Install X-axis Drag Chain Plate: Secure the X-axis drag chain plate with M4*6 screws.
- Mounting Tow Chain: Install the tow chain and secure it with M4*6 screws.
- Interface Diagram: Connect the Y2, Y1, X-axis, Z-axis motors, Laser, Set knife, Z-axis limit, Y-axis limit, Main shaft, USB Interface, X-axis limit, and Off-line handle as per the diagram.
Software Operation
- Driver Installation: Install the necessary driver (e.g., CH340SE) from the provided U disk.
- Control Software: Open the Candle control software.
- COM Port Determination: Identify the machine's COM port through Device Manager (e.g., USB-SERIAL CH340 (COMX)).
- Port and Baud Rate Selection: Select the correct COM port and baud rate (e.g., 115200) in the software.
- Connection Confirmation: Verify successful connection by observing the "Idle" status in the software.
- G-code Import: Import G-code files into the software.
- Tool Clamping: Securely clamp the tool.
- Origin Setting: Move the machine to the starting point of the code and clear the X, Y, Z origin.
- Run Code: Click "Send" to initiate the engraving process.
Maintenance Features
Matters Need Attention (Safety and General Maintenance)
- Eye Protection: Always wear protective glasses to prevent eye injury.
- Power Disconnection: Disconnect power before replacing tools, assembling/disassembling the unit, or performing maintenance.
- Unplugging: Unplug the unit when not in use or before replacing parts.
- Supervision: Close supervision is required when children are near the appliance.
- Avoid Jamming: Do not force the unit to operate under excessive pressure.
- Water Immersion: Do not immerse wires or the machine in water to prevent electric shock.
- User Competence: The appliance is not intended for use by persons with reduced physical, sensory, or mental capabilities unless supervised or instructed by a responsible person.
- Cord/Plug Damage: If the supply cord or plug is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons. Do not operate a damaged appliance; return it for professional service.
Fault Analysis and Countermeasures
- Engraving Machine Milling Bottom Uneven:
- Analysis: Spindle is not perpendicular to the table.
- Countermeasure: Calibrate and level the Z-axis, or use the engraving machine spindle to mill the flat plate for leveling.
- Uniaxial or Triaxial Movement is Abnormal:
- Analysis: Corresponding shaft connector is loose, or the corresponding motor wire is loose.
- Countermeasure: Tighten screws securing the shaft connector, and reinsert the motor wire.
- Offset Distance Varies When Setting the Origin:
- Analysis: Limit line is loose, or the limit switch failed.
- Countermeasure: Check if the limit line is loose, or change the limit switch.
- Engraving Misalignment:
- Analysis: Engraving speed is set too fast, or static electricity/external interference.
- Countermeasure: Slow down the carving speed. Check if the machine is grounded or if other high-power appliances are running in the circuit.
