Hi so I've just finished wiring everything and my raspberry pi is giving a low voltage warning in octoprint. I've tried with an external USB plug (even using the same cable!) and it works fine, so I'm guessing it's something off with the included USB adaptor thingy. I've got a 3B+ Pi, if that makes any difference. I've not plugged in the camera or anything yet so that's not drawing any power from the pi (not sure if that'd even affect the voltage) I tried checking the connections in the terminal block and they're all fine, taking them out and putting them back in made no difference.
