Laser cutter Tips and Tricks

for AutoCAD

  • DO NOT use Black/White Layer.
  • Make sure you are in a 2D format. The laser cutter will not read 3D files.
  • The maximum size of material is 31-3/4" x 17-3/4". A minimum of 1/4" extra material around the part is required on all sides. This is due to the laser cutters tolerance offset.
  • Use separate layers for Cut and Etch. Linetypes should be set to DEFAULT, otherwise they will read as a hatch.
    Note: Hatch will take longer to cut, and cost more money.
  • Share lines; sharing lines will make your file more efficient and save you time and money
  • Cutting should occur after scoring so the pieces don't become loose as you etch.
  • Don't forget to run “OVERKILL” command to clean up overlapping lines. The “Overkill” command may need to be performed more than once.
  • Remove educational plot stamp; save “dwg file” to a “dxf file,” open your “dxf file” and save it back to a “dwg file”
  • Use correct power and speed settings
  • Universal laser pen setting
  • If Universal Pen settings are missing, they can be found on the “S:/drive” in the Library folder > Laser folder > “Universal Laser.ctb” should be dragged into AutoCad Plot Style Manager (located under the Print Tad)
  • Select Laser Cutter as your plotter
  • You must have flat material, no waves or bends. Pay attention to the material you purchase and how you store it.
  • Please remove only one side of acrylic protective sheet.
  • In order to pick up your completed laser cuts, you must have sufficient funds on Campus Cash Account.
