TBM stands for Tunnel Boring Machine, and is used to make tunnels.
When you place it,it will face the same way as you placed it, and will dig in that direction.
Right-click it, and you will get a formspec. On the left you will see 4 labeled slots, for coke, floor blocks, torches and rails. On the right will be empty space where mined items will go.
Place the necessary items on the left, and it will start digging. All dug items will end up in the chest-type area on the right. RAILS ARE OPTIONAL!
To stop, just take something out of the necessary slot, eg remove the cobble.
Choose what floor material to use
- With Technic, it will drop the nodes as items, and add them to its inventory, doubling the mined items.
- Try to avoid driving it through the 0 of either x, y, or z axis
- Try to also avoid driving under any falling node like gravel or sand, this may cause the TBM to drop as an item, losing the contents
