Ender Quarry

The Ender Quarry is a block added by Extra Utilities. It is designed to be a low lag alternative to the BuildCraft Quarry. It runs off Redstone Flux (RF), consuming 260RF/t 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
Once you have placed the Ender Quarry you will need to specify the area for it to mine. To do this you have two options; vanilla fences or Ender-Markers.

Fences are very straight forward. Start by placing a fence directly in front of the Quarry. Continue to outline the boundary around all of the blocks you want to mine.

Ender-Markers are very similar but also much easier when setting up a very large area to be mined. You will need three Ender-Markers total; the first directly in front of the Quarry, the second needs to be at the same y-level and in line along either the x or z axis of the first Ender-Marker, the third Marker is the same as the second, just along the other axis, x or z, that you went with the second.

For example, if you place the first marker at x=0 y=60 z=0, the second marker will need to go at x=100 (or any number. I don't go over 1000 blocks away from the first marker typically.) y=60 z=0, and the third needs to go at x=0 y=60 z=100 (or any number.) When placed in line with each other, the Ender-Marker with have purple particle effects pointing in the direction of the other Markers. If you are not seeing these particles, the Ender-Markers are not aligned.

Once you have completed your boundary with either the fences or Ender-Markers, you can right-click on the Quarry. If everything is set up correctly you will get the message 'Successfully Established Boundary'. Now that the area to mine is set, you can attach any upgrades you are going to use with the quarry and add power and an inventory for the mined blocks to go. A Tesseract can supply both power and receive items when placed on the top.

Note: The blocks underneath the fences or Ender-Markers themselves will not be mined, only those inside the boundary.

At maximum speed, barring no energy shortages or storage back-ups, a 1000 block x 1000 block quarry will take about 5 real life days to complete.
