You preferably use software buttons in the host/streaming application to stop (gracefully) If you want an EMERGENCY stop, it should never rely on just do a software/firmware based motion-pause/stop (which is why we didn't add an input to lure you into a false sense of safety with): What would the nature of an emergency be? Hand caught in router bit, power supply on fire, computer on fire, router on fire? A button stopping movement does nothing about these. An emergency stop should always be wired so it cuts ALL power to ALL accesories in use (ie before a power strip)
