so I was setting up the sprocket, I then had to go out with family so decided to unplug it and put it in its case for a few hours and try to print one when I get home. When I got home I successfully printed a photo, I showed the photo to the family and then when I came pack to the sprocket it won’t turn on. The light was orange. I pressed the button but the LED didn’t turn on so I looked at the charge and it was over half way charged. Why did it not turn on?
