I wanted my turtles to mine in the same pattern that i would when i do my branch mining and to do so without losing materials and placing torches ect. All programs handle gravel and running out of fuel.

http://pastebin.com/6WfssKvz - 6WfssKvz - sTunnel (Smart Tunnel) Digs a 3 high tunnel in the width and length specified. Will add torches and road blocks if provided. Depending on the type of house that i create i use this either for branch mining (trunk and branches) or i use it to create the trunks for sqtunnel.

http://pastebin.com/HzbwMFVy - HzbwMFVy - sqTunnel (Square Tunnel) Digs the perimeter of a square starting from the midpoint on one side. (turning left only Nascar style.) i create a 3x3 hole to y=11 then dig these tunnels every 3 blocks (tunnel then 2 spaces then tunnel) like the rings of a square tree. I use stunnel to create 1 wide tunnels in the cardinal directions for easy access to all sides of the rings.

http://pastebin.com/YgAui7aC - YgAui7aC - Ladder (Ladder) Digs and builds a ladder up to 64 blocks then returns up or down based on specified direction of travel. used when creating new mineshafts. or in flatcore to create platforms ladders.
