The power and speed laser parameters are the most important settings in the material database. They can be set as a percentage between 0 and 100 percent.
The power laser parameter describes the output power of the laser. Maximum power is 100 percent. For dark wood engravings or stamp engravings, you generally need high power, whereas low values are used for materials such as paper.
The speed laser parameter describes the movement of the laser head. Fast speeds lead to short exposure times, and slow speeds lead to long exposure times. For example, large-scale engravings of acrylic materials are engraved at high speeds between 80 and 100 percent, but for photo engravings with a lot of detail on wood, the speed should not exceed 10 percent. This setting also affects the quality of the laser cut.
Note that cutting and engraving speeds are not comparable. Basically, cutting is slower than engraving. A “high” cutting speed is 10 percent.
