Take the downlooking camera. My supplier changed the lens design, the newer lens is shorter. If the lens doesn’t reach below the while light diffuser, remove the diffuser, so you can set the focus of the camera at the setup stage. Attach the camera to the gantry front plate, using the low head screws supplied. Note, that the camera is supplied mounted to the second most lowest mounting hole set. In the image below, the diffuser is attached; note also the slots to secure the cables.
