In order to have your turtle move back to the "home" position you will need to track how far it has moved.

Have a read.

Funny feeling of deja vu here. You may find this thread worth a read.

Why would people ask about problems with ComputerCraft on the FTB forums… especially when there are these awesome forums… some people leave me perplexed…

First off, don't use turtle.compareUp() and turtle.compareDown() if all you want to do is see if there is a block in that direction.Use turtle.detectUp() and turtle.detectDown() instead. Also, you do not have to put the "== true" and "== false" in there as a while loop defaults to checking if the condition is true. Putting "not" in front of what you are checking will have it run while the condition is false.

Here is a simpler version of the code that should leave the turtle in the place where it started, waiting for another sapling to grow.

-- turtle digs in front and moves forward
turtle.dig()
turtle.forward()

-- turtle checks to see if there is a block above. he stops when there is nothing above him
while turtle.detectUp() do
  turtle.digUp()
  turtle.up()
end

-- turtle checks to see if there is a block below. he stops when there is a block below him
while not turtle.detectDown() do
   turtle.down()
end

turtle.back()
