The Auto Focus Plunger (AFP) plays a critical role in your Epilog Fusion Pro laser system by enabling
automatic focusing of the laser bed. This feature allows the table to adjust its height precisely, ensuring
the laser is always focused at the optimal distance from the material. Accurate autofocus improves cut
quality, engraving precision, and overall workflow efficiency. If the AFP becomes damaged or worn out,
replacing it is essential to maintain proper focusing functionality and to avoid manual adjustments
that can lead to inconsistent results.
