In short, yes. If your endstop switches are not wired or configured correctly, though, the axes won't travel toward them.

I looked at your video and it looks very much like there's a problem with the end stops. Two things to check: firstly that the wiring is OK and secondly that they're configured correctly. First make sure that the wiring is OK, then send M119 to the printer. This will tell you whether or not they're triggered. If the Z axis is raised, but M119 tells you the end stop is triggered, then you need to invert them in the Marlin configuration (search for the end stop section and it should be reasonably obvious where to invert them - if not, ask here). From the video, the Z axis raises when you try to home it, but then won't go down. This is generally what happens when the end stop isn't configured correctly.

You might have the temperature a bit high. What type of plastic are you using and what temperature are you printing at? Also, fixing homing and end stops will help with the height above the bed problem.
