Quarry



Quarry is a machine that automatically mines blocks to the bottom-right from where it's placed. It will also collect anything it encounters while mining, including vines, chests, etc. It acts as a 16-slots storage and stores everything inside. It doesn't require any Power.

Normally the Quarry will only mine foreground blocks. To make it mine background blocks, wire its second to something that provides "ON" signal (for example, Signal Emitter or Iron Lever).

At the very beginning of its work (when the Quarry is just placed) it extends its "hand" to the right, up to the maximum reachable horizontal distance (for example, 36 blocks for Iron Quarry). The Quarry can only mine directly below its arm. If there were solid blocks in the way that prevented the arm to be extended, then Quarry will have less horizontal reach than it otherwise would.

Possible uses

 * After you arrive to a new planet, you can place a Quarry and then go exploring. By the time you return, some free blocks will be waiting for you.
 * Quarry can clean a large rectangular area when you want to build something large underground.
 * To clean unwanted background walls.
 * For in-world liquid mixing that produces blocks, e.g. to remove Clay from a lake with Contaminated Water and Poison.

Limiting the area

 * Limiting the horizontal reach (when you want the Quarry to NOT mine further than N blocks to the right) is easy: before placing a Quarry, place a block that will be in the way of Quarry arm's attempt to extend to the right.
 * To limit the vertical reach (how deep can Quarry mine), you will need to use Field Generator to apply tile protection to the bottom of intended pit. Quarry mines from top to bottom, and it won't be able to remove tile-protectd blocks, so it will stop at the depth where it encounters them.
 * Alternatively, when mining near the surface, you can place Quarry high in the air (for example, if you want to dig a pit of depth 20 using a Copper Quarry, which would normally dig to depth 36, you can place that Quarry 16 blocks above the surface).
