Directions for using AutoCAD with laser cutter. They are fairly basic
requirements, but following them will save time and material when
cutting. [MS Word DOC]
- Sample of laser cutter output (penny is for reference) is given in the image to the left.
- This AutoCAD template [DWG] which should be used for all drawings. It was created to match the dimensions of the cutting area in the laser cutter.

Materials
- Acrylic/Plexiglass is
the preferred material; we have tested the cutter with it and have an
idea about the settings required by it. Acrylic sheets up to 6 mm can
be cut. 8 mm is the specified upper limit, but we cannot be sure the
laser will be able to cut through that thickness.
