7" touch screen and bluetooth keyboard controller

I decided I wanted something a little more compact to control my machine. I found a 7" touch screen on Amazon I could hookup to my laptop and I had a mini Bluetooth keyboard floating around.

The screen is mounted up top off to the one side of the machine. It's plugged into my laptop, which is sitting in the drawer below. I programmed the keys from the mini Bluetooth keyboard so I can control the X,Y and Z movements...along with a few other functions.

Here are the links to the screen and the keyboard:

Unfortunately, it doesn't scale properly.
