5. Istruzioni per l'uso
Operating your OMTech laser engraver involves preparing your design, setting parameters, and initiating the engraving/cutting process.
- Caricamento del materiale: Place your material onto the honeycomb or blade bed. Ensure it lies flat for consistent results. The two-way pass-through doors allow for larger items.
- Manual Focus Workbed: Adjust the workbed height to achieve the perfect focal distance for your material. This is crucial for engraving quality.
- Design Preparation (LightBurn): Import or create your design in LightBurn. Adjust size, position, and assign layers for engraving or cutting.
- Impostazione dei parametri: For engraving, adjust speed (up to 23.6 ips / 600 mm/s) and power settings based on material type and desired depth. For cutting, set appropriate speed and power to achieve a clean cut.
- Initiate Process: Send the job to the laser engraver from LightBurn. Monitor the process closely.
