Another program of mine. This one digs down, and if the item in the first slot is the same as around it, it'll break it. This can be used for ore-side mining.
Also will not operate unless fuel is sufficient.

Default:
Type this in a mining turtle with http on. Enable in the config.
pastebin get KRhN9Asu startup

Superflat:
Again, type this in a mining turtle with http on. Enable in the config.
pastebin get H4KZatBr startup

Enjoy :)/>
