3. Mount the vertical column onto the main base unit. Ensure it is firmly attached.
4. If using, attach the 20cm raised column for additional working height.

5.2 Power Connection & Initial Start-up

1. Connect the power cable to the machine and a suitable power outlet. The machine supports 110V/220V, and the plug type will be matched to your region.
2. Locate the main power switch on the rear of the machine and turn it ON.
3. The machine features an emergency stop switch (red button). This button is normally in the closed (pressed) position for safety. To start operation, twist or pull the emergency stop button to release it.

5.3 Software Installation

Insert the provided USB flash drive into your computer. Install the engraving software (Lightburn or EZCAD, depending on your machine's motherboard) by following the instructions on the drive or in the manual. Ensure your computer meets the system requirements (Windows XP/7/8/10/11 or Mac OS).

5.4 Focusing

Accurate focusing is crucial for precise engraving results.

• Mechanical Rotary Focus: Manually adjust the lens height by rotating the focus knob until the laser spot is at its smallest and sharpest point on the material surface.
• Dual Red Focus: The machine is equipped with an intelligent dual red light fixed focus function. This feature helps to quickly and conveniently adjust the focus and locate the engraving area. Align the two red dots to achieve optimal focus.
