How to Use the 50w Laser Cutter

Note: You must be trained to use it before handling it alone.
Please contact James Pittman to set up training on it.

Training Slides

Specifications

  • Effective cutting space is 24“x12.5”, or 18“x19.5”, depending on how you orient things.
  • The laser is capable of cutting up to 1/4“ thickness.
  • Software is called RDCAM/LaserWorks.
  • Machine home is typically upper lefthand corner.

Settings

Here are suggested settings for different materials:

  • Cutting power should never be set above 80.
Material Etch/Cut Power % Speed (mm/s)
Corregated Cardboard Cut 80% 25
Plywood (3/16” thick) Cut 80% 12
Glass (clear, rotary) Etch 80% 500
Acrylic (0.093“ thick) Cut 80% 17

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.
