I think one of my motors are lose but I dont know how to access the srews to check.. can someone send me a video or something on how I check this

I don't have a video, however the mounting screws are under the four clear plastic discs that cover the leds  right under the motors. Make sure you have the right kind and size of key (don't know †hat either, it is hex and very very tiny...)

Before you do that post a video first. Some of the motors are looser than the others . It might feel that they are loose but they are not!

Agree with 3#. Post a short video for better assistance.
