3. Setup Instructions
Follow these steps to assemble and prepare your ACMER S2 Laser Engraver for first use.
- Assembly: Carefully assemble the machine frame according to the detailed instructions provided in the included user manual. Ensure all screws are tightened securely. The screw bags are conveniently labeled by step for ease of assembly.
- Connect Cables: Connect the USB cable from the engraver to your computer and the power adapter to the machine and a power outlet.
- Software Installation: Install the necessary drivers and engraving software (e.g., LaserGRBL or LightBurn) on your computer. These are typically available for download from the manufacturer's website.
- Focusing the Laser: Use the provided gauge block to set the correct focal length for the laser module. Loosen the laser module's adjustment screw, place the gauge block under the laser, lower the module until it touches the block, then tighten the screw. This ensures optimal engraving and cutting precision.
- Workspace Preparation: Place the material to be engraved or cut on the honeycomb workbed. It is recommended to use a protective pad underneath to prevent damage to your work surface.
