4. Operating Instructions
4.1 Material Preparation
The ACMER T1 can engrave and cut a wide range of materials. Ensure your material is flat and securely placed within the working area.
- Supported Materials: Wood, bamboo, paper, plastic, leather, PCBs, aluminum oxide, painted and non-reflective lacquered metals, ceramics.
- Unsupported Materials: Highly reflective metals (e.g., polished stainless steel, copper), transparent materials (e.g., clear acrylic, glass without coating), PVC, and other materials that produce toxic fumes when laser-processed.

4.2 Software Operation
- Open your chosen engraving software (e.g., LightBurn).
- Import your design file (JPG, PNG, BMP, DXF are supported).
- Adjust laser parameters (power, speed, passes) according to the material and desired effect. Refer to the software's documentation for detailed parameter settings.
- Position your design on the virtual work area to match the physical material placement.
- Perform a frame test (if available in software) to ensure the laser path is within the material boundaries.
