Calibrating your laser engraver is essential for achieving optimal performance. Follow these steps to ensure accurate and consistent results:

1. Level the Table: Begin by ensuring that the engraving table is perfectly level. Use a spirit level to check both the X and Y axes. Adjust the legs or use shims if necessary.
2. Focus the Lens: Properly focusing the lens is critical. Use a focus tool or piece of material that matches your engraving depth, adjusting the lens until the beam is at its smallest point.
3. Check Alignment: Make sure the laser head is aligned with the bed. Run a test engraving on a scrap piece and verify if the design matches your intended starting point.
4. Adjust Speed and Power Settings: Conduct test engravings with different speed and power settings. Document the results to establish optimal parameters for various materials.
5. Calibration Test: Run a calibration pattern, such as a grid or circle, to confirm precision. Adjust settings as needed based on the test outcomes.
6. Regular Maintenance: Clean the lens and mirrors regularly, and check for any wear or damage to ensure continued accuracy.

By following these calibration steps, you’ll enhance the performance and efficiency of your laser engraver.
