== What can be cut? ==
Acrylic (plexiglass) is a solid performer.
Plywood works great in the laser cutter as long as it's not MDF core. On both the Epilog and Boss lasers, MDF core plywood has the frustrating tendency to almost cut all the way through, but fail. Almost all of Owl Lumber's plywood is MDF core.
MDF itself is very good, but requires almost double the power (or half the speed) for cutting an equivalent sheet of plywood. It warps far less than plywood does.
There are many other materials good for cutting, as well as materials that won't cut well, or worse, may damage the machine. All kinds of foam are not recommended because foam can catch fire incredibly easily. Read below for details about other materials.

* '''PVC (Poly Vinyl Chloride):''' Also known as '''"vinyl"''' '''"pleather"''' or '''"artificial leather."''' Most adhesive vinyl shelf paper (e.g. Con-Tact Paper) also is PVC. Emits HCl and nasty chlorinated compounds when cut! Don't ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system.
