1. A woodworking machine having a cutting region for cutting workpieces, the woodworking machine comprising:
- a cutting tool configured to extend at least partially into the cutting, region;
a detection system adapted to detect a dangerous condition between a person and the cutting tool;
a reaction system associated with the detection system and the cutting tool, where the reaction system is configured to move the cutting tool at least partially out of the cutting region upon detection of the dangerous condition by the detection system; and
a stop positioned to limit continued movement of the cutting tool after the cutting tool has moved out of the cutting region a predetermined amount.
