4. Configuración

4.1 Asemblea

1. Retire coidadosamente todos os compoñentes da embalaxe.
2. Place the main tower and work table on a stable, level surface.
3. Attach the laser arm to the support column using the provided bolts and hex wrenches. Ensure the lens is positioned above the work area.
4. Connect the cable from the laser arm to the main tower.
5. Connect the USB cable from the main tower to your computer.
6. Connect the foot pedal switch to the main tower.
7. Connect the power cord to the main tower and a standard 110V power outlet.

4.2 Initial Power-Up and Software Installation

1. Turn on the machine's emergency stop switch (red button) by rotating it clockwise.
2. Insert the key into the "Scan Head" switch and turn it to the ON position.
3. Insert the provided USB flash drive into your computer. Copy the software and drivers to your computer's hard drive.
4. Open your computer's Device Manager, locate the unrecognized machine (e.g., USB LMCV4), and install the drivers from the copied files.
5. Open the EZCad software. Set the machine parameters as indicated in the provided parameter screenshots on the USB drive.

4.3 Enfoque do láser

Accurate focusing is crucial for optimal engraving results. The machine features dual red dot locators for precise focusing.

1. Place your material on the work table.
2. Use the provided steel ruler to measure the distance from the surface of the material to the lower edge of the red stripe on the galvanometer scanning head. This distance should match the focal length marked on the nameplate (e.g., 175mm, 361mm).
3. Turn the adjustment wheel on the support column to raise or lower the laser arm until the measured distance is correct.
4. When correctly focused, the two red dots projected onto the material will converge into a single, sharp red dot.

5. Instrucións de funcionamento

5.1 Proceso básico de gravado

1. Ensure the machine is properly set up and focused.
2. Open the EZCad or LightBurn software on your computer.
3. Import your design diagram into the software.
4. Adjust the engraving parameters (power, speed, frequency) according to your material and desired effect.
5. Use the "Frame" function in the software to preview the actual size and position of your design on the material using the red dot pointers. Adjust as necessary.
6. Wear your laser safety goggles.
7. Press the "Fiber Laser" button on the main tower to activate the laser.
8. Inicia o proceso de gravado desde o software.
9. Once engraving is complete, press the "Fiber Laser" button again to stop the laser. Turn the key on the "Scan Head" switch to OFF and press the emergency stop button.

5.2 Using the Rotary Axis

The included rotary axis allows for engraving on curved or cylindrical surfaces.

1. Connect the rotary axis to the designated port on the main tower.
2. Secure your cylindrical object (e.g., ring, tumbler) onto the rotary axis chuck.
3. Adjust the laser focus for the curved surface.
4. In the software, enable and configure the rotary axis settings according to the object's dimensions.
5. Proceed with engraving as per the basic operating instructions.
