Ender Quarry

The Ender Quarry is designed to be a low lag alternative to the Buildcraft Quarry. It runs off Redstone Flux, consuming 260RF/Tick at full speed. Instead of mining laterally, one layer at a time, like the Quarry, it mines vertically. The Ender Quarry does not break the block it mines, but replaces it with dirt, without a block update, thereby preventing the lag caused by rapid block updates. The Ender Quarry self-chunkloads like the Ender-Thermic Pump, loading the chunk it is in, and the chunk it is currently mining. The Ender Quarry will emit purple 'portal' particles above the column it is currently mining, and when right clicked while running will show the percentage completion of the quarry to two decimal places, and the coordinates where it is currently mining. If the Quarry has completed, or has nowhere to put items, it will stop running, but continue to draw power.

Setup
To set the area the Ender Quarry will mine, you must outline the rectangular area you wish to mine with vanilla wood or netherbrick Fences (XU Microblock Fences also work) - note that the blocks underneath the fences themselves will not be mined, only those inside the area, with the Ender Quarry inside this fence boundary. Then, right click the Ender Quarry. If it says 'Successfully Established Boundary' and the Ender Quarry gains a lighter green texture you are good to go, else it will tell you the coordinates of the problem with the boundary. Now, place a block with an inventory on top of the quarry, and supply power - a Tesseract can supply both power and receive items when placed on the top. The fence boundary has a minimum size of 3x3 within the boundary no max size.
