=== Vectoring ===
=== Vectoring ===
Vectoring consists of following vector lines specified in your program. Vectoring is most often used to cut through a material. However, at lower settings it can also be used to engrave. Instead of moving back and forth, the laser is following a “vector”. A vector is a line with a specified direction and magnitude. In other words, a line that connects two points. Our laser has a point of 0.001” (0.0254 mm) in diameter. For a line to be recognized as a vector, the line width has to be the size of the point. We will explain how to do this further in this document.

##'''Power:''' Determines the amount of laser energy that is delivered to the piece being cut/engraved and is adjustable in 1% increments.Each materials have their own specific value and can be in “Suggested Material settings” which is located next to the laser cutters in Makerspace.

##'''Frequency:''' Determines the number of laser pulses per inch of cut.Lower the frequency,the less heat being applied to the material. The frequency can range between 1 to 5000..Each materials have their own specific value and can be in “Suggested Material settings” which is located next to the laser cutters in Makerspace.

The pictures below shows the laser cutters available for use at the Makerspace. The biggest difference between the two laser is the build volume. The Epilog Helix can cut materials with a maximum size of 24 x 18 in while the Epilog mini can cut with a maximum size of 24 x 12.
