Single Axis stage build

I am currently working on designing and building a single axis stage to move a hot wire anemometer up and down over our 50' wave tank.  I have the general design completed and have been working on the programming aspects of this project but have run into some difficulty then I had an idea.  Instead of reinventing the whole wheel, I may as well post what I am doing here and maybe someone has done something similar and would be willing to lend their expertise or even share some code to make this simpler.  

Below is part of the write up from my README file I am also hoping to attach an image of what it will look like to make it easier to follow.  

If you look at the image you can see the graphic I have created showing the
basics of the layout and requirements of the Z-Stage platform.

There are 5 buttons labeled with what they do below. (momentary)
1. Home button -- This button moves the stage to top until the top limit
is triggered then the program waits for other buttons.
2. Start button -- This button moves the stage from whatever position it
sits at down until it triggers the bottom limit switch then moves up until
the top limit switch is triggered
3. Jog Up -- This button moves the stage up as long as the button is depressed
4. Jog Down -- This button moves the stage down as long as the button is
depressed
5. Speed H/L -- This button uses one of the UNO interrupts to monitor for a
change then set the speed to either high or low (This button will also
require hardware debouncing due to using the interrupts)

How it is intended to work below:

Initial setup for the first time at that water height:
1. On power up the stage will just sit and wait for user input via the buttons.
2. The user will jog the stage down til just above the water surface then adjust
the mechanical stop trigger on the bottom until the LED lights up (Need to
add the LED part yet)
3. The user will then hit the home button to return the stage to the top position
where it will sit and wait for the cycle start
4. The user will press the cycle start which will cause the stage to move
down to the bottom limit switch and on triggering it will cause it to return
to the home position (Maybe use a home function called when the bottom switch
is triggered in that function?)

Subsequent operations after the initial setup is complete:
1. The user will use the home button to return the stage to the top of the system
and await a press of the cycle start button.
2. User will set the data collection computer to record data (separate system)
then press cycle start to cause the stage to go through its down then up cycle.

Thank you for taking the time to slog through my wall of text.  If you have thoughts ideas or suggestions I am totally open to them as well as constructive criticism.  My background is primarily ME and fabrication and machining but this project came up and I thought it would be great to expand what I can do.

Thanks again,
