The laser in a laser engraving machine is a powerful processing tool, capable of marking, engraving, and cutting a wide variety of materials.
The Gravograph laser machines have a unique feature that allows quick selection between the two methods. It is a manually-actuated slider valve, located inside the cabinet. Sliding this valve to the left actuates the rear exhaust. Sliding to the right opens the head exhaust port.
Each has advantages and disadvantages based on the application. Regardless of which method is used, control of the fumes when they exit the lasing cabinet is crucial. Below is a diagram showing the two exhaust configurations.
