I've been trying to find a good quarry program for a while and yesterday i gave up and made one myself.
You can change the width, length and height.

code:

The turtle will dig until area is clear.
When full the turtle will return to start and drop all items on the block behind it, then go back to the spot and keep digging.
I use a transposer behind the turtle connected to a chest and the turtle will drop all items in the chest, i don't have 1.4 yet, so i don't have the fuel option and putting items directly into chests.
I'm not very good at lua, so please feel free to suggest any changes to the code.
enjoy =P
PS: anyone know how to save variables in a file or something so it keeps the coords after reboot?
