Focusing the Laser

From ProtoLab Wiki

The Epilog Laser Cutter automatically focuses itself depending on the material being used. For extremely precise cuts, it may be safest to manually focus the laser. To manually focus, use the triangular focus tool stored near the machine and press the "Focus" button on the cutter. Place the tool on the laser and use the arrow buttons to raise the bed until the tool and material just barely touch. Once you are satisfied with this, removed the tool and press "Go" to begin your cut!
