Abstract
An electrically controlled pattern tracer selectively uses stored detected pattern information from a sensor differently depending upon the value of a selected entered kerf entered to control the tracing element to follow a pattern turn. The tracer also distinguishes one type of pattern turn from another and delays use of stored pattern information for control of the tracing element by different amounts depending upon the type of turn detected and the entered kerf.
