Ug. More things to note.
first: if you have the heated bed, I hope you read this before assembling... holes at the edge of the base plate goes on left side of printer. Single hole, goes towards the front left corner, that is where you should mount you camera... not back right like I had to do.
Before putting the camera module into your 3D printed case, check to make sure it is taped down. Mine they forgot to peel off the “3M” backing so was only held in place by the tiny plug. after I got everything mounted I tilted printer up to plug things in and the camera fell out. Had to take it all apart plug the little camera part back on and stick it onto the circuit board.
i used a Raspberry Pi 3B+ ... their right angle power adapter us backwards from third picture. Also, hooked to the main 24v feed (so many extra wires jammed in that terminal now) and get an under voltage error in OctoPi web interface.
Camera stream doesn’t work either - maybe because of undervoltage. Will try and reseat cable ends tomorrow.
Under voltage also causes Octopi/Octoprint to be unable to update.
