After entering the layer parameters, set the carving and cutting parameters respectively according to the actual power of the equipment and the actual thickness, as shown in the following figure：
To facilitate observation, you can check the simulation display carving layer, and the filled part is the engraved part, as shown in the following figure:
Make sure the sculpt layer is above the cut layer, and check sort by layer at the optimized sort settings, as shown in the following figure:
Load the processing file into the laser machine, place the plate and position it, and then start the processing.
