Cutting Edge Features:
As you engrave, debris such as smoke and dust land on your focal lens, building up a layer of residue over time that absorbs laser beam power and can stain the lens permanently. Eventually, this lost power will affect your machine’s precision and throw off your laser settings. To keep your device running at its full potential, we recommend inspecting and cleaning the optics system once a week and replacing the mirrors or focal lens as soon they get damaged.
How to Select the Proper Focal Length:
A lens with a shorter focal length (1.5"–2.5") has a smaller focal point to provide sharper details for high-resolution images. A longer focal length (usually up to 4") has a larger focal point and extended depth of focus (or focus tolerance) which is better suited for cutting applications. Also, keep in mind that using longer focal lengths subtract from your workbed’s Z-depth.
