An “E-STOP” (Emergency Stop) is a safety feature used to immediately disable laser output in case of an emergency. It is part of the interlock system, which is designed to ensure that all laser projectors in a daisy-chained setup are safely controlled. If any event triggers the interlock (e.g., power loss, emergency switch activation), the E-STOP will shut down the laser output. To resume operation, the issue must be resolved, and the START button on the E-STOP remote must be pressed, after which there’s a brief delay before the system can be used again.
