There's an option to use Turtle Control Software with Raspicam connected instead of stock USB camera.
To do that you'll need to disconnect the stock USB camera, disconnect Turtle Electronics from Raspberry Pi and connect Raspicam to Raspberry Pi camera connector (please mind the tape connector orientation and the right port to connect).
Put the Electronics back on Raspberry Pi as you route the tape the way you like.
