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.
