Another less common accessory is the digitizing probe, which is used to take a design and reproduce it. The probe is mounted in the collet, a steel sleeve that holds the bit, and moves in small increments over the item to be copied, memorizing it with every touch until the whole image is recreated for a file format. The result is a copy or scan of the image. "If you have an item that is hand- carved or something you found that you want to re-machine or incorporate into the sign, probing the item to a file can allow you to do that," Warner says. If sign makers are printing an image on a flatbed printer to cut it into a mate- rial, they can use a Vision Registration System. The system, geared for odd- shaped items, consists of a computer pro- gram and a registration camera that finds the registration materials on the printer sheet, so the router knows where to make the cuts. The program will command the router to find three dots to be able to locate and then position the object, ignoring the other parts of the design. Without it, sign makers have to ori- ent and scale a photograph or a traced drawing of the image to do the cutting, Warner says. "Accessories take advantage of the useful available functions that are often overlooked by CNC owners," Warner says. "Having the right bits or accesso- ries available often make the difference in profitable production."
