Tips and Tricks

  • The harder the wood, the more power/less speed it will take to cut.
  • Plywood takes more power/less speed than solid wood of the same thickness.
  • The kerf of the laser is often around .5mm. Keep this in mind if cutting pieces that are designed to fit together. (Kerf is the amount of material that is removed by the cutting element. With saws, it is the thickness of the saw blade.)
  • The kerf will also be variable from the top to the bottom of the laser-cut piece, being wider on the top and thinner near the bottom. The variation will be more pronounced in thicker materials.
