I watched on the Bambu Studio video feed as my printhead crashed into a print on the bed (due to user error).
But there is no big red STOP button to cancel a movement, only a (very small) stop button to cancel a print—in this case there was no print in progress.
There’s also a stop button under the camera feed that disconnects the feed. This is also not great, because when you’re scrambling for something square-shaped in an emergency, the one closest to the video feed is the one your eye is drawn to first. I recommend changing that to something else (eye open/closed for example).
