Testing your laser settings on a scrap piece before engraving your final board is critical for several reasons. Firstly, every material reacts differently to laser engraving, and settings that work perfectly for one type may not yield the same results for another. By testing, you can ensure that the power, speed, and frequency settings are optimized for your specific material, which helps to achieve the desired engraving quality.

Secondly, this practice allows you to assess the depth and detail of the engraving. Engraving too deeply can damage the material, while insufficient power may result in faint or incomplete designs. Evaluating the results on a scrap piece helps prevent costly mistakes on your final product.

Furthermore, adjustments based on the test can save you time and resources in the long run. It minimizes the risk of having to redo a project, which can be frustrating and time-consuming. Lastly, using a scrap piece encourages creativity and experimentation—allowing you to fine-tune settings and explore various designs without the pressure of ruining an important project. Overall, pre-testing ensures a smoother workflow and enhances the quality of your final engraving.
