Why didn't the RDD6584G vibrating knife Mark visual positioning machine perform any action?

I was using the RDD6584G vibration knife control system for Mark visual positioning machining when I started the equipment and loaded the machining file, preparing for visual positioning cutting. When the device reaches the Mark point recognition process, the positioning point can already be clearly seen in the camera image, and the Mark point is also within the effective recognition area set by the camera, but the device does not continue to perform the action. The machine remains at the current step, without moving or entering the next cutting process. Any ideas?
