Track enhacing is a feature that moves your material back and forth through the Silhouette machine prior to the actual cutting process.
As material thickness increases, the rollers (dependent upon the material type and surface) might not grip as firmly on the material's surface during operation. In such cases, you may enable the Track Enhancing option. The action of feeding the material through the Silhouette several times prior to operation creates a "track" on the material's edges for the Silhouette to gain a better grip upon during the actual job. The feature attempts to ensure proper alignment of secondary passes performed and may resolve potential cutting mis-alignment concerns.
This option is only needed when cutting thicker materials where the material appears to be otherwise slipping during the cutting action, or when there is mis-alignment when cutting multiple passes.
