It's more reliable to place four land marks in a square. Remember that the maximum quarry size is 64x64, so if your quarry is bigger than that it won't work. Once you've placed your land marks, right click one of them and if they've been placed successfully a red cuboid frame will appear. That will be the frame of your quarry. Next place the quarry down next to any of the land marks. The red frame should change to yellow and black stripes, and all the land marks except one will drop as items (one land mark won't drop, just hit it with your hand and you'll be able to pick it up again). After that, you'll have to supply your quarry with sufficient energy. Quarries can run at any speed up to 5 blocks per second, but a fair amount of power is needed to get them up to a speed at which they can run effectively. You can use either BuildCraft engines (you will need a minimum of three steam or two combustion to run the quarry at a good speed, redstone engines just aren't strong enough) or you can use IndustrialCraft electricity. If you're going to use IC power, you'll need an energy link. Place the energy link directly next to the quarry and connect your BatBox/MFE/MFSU to the energy link with the appropriate cable. Bear in mind that quarries use quite a lot of EU, so you will need a large power source. Sufficient energy is provided by:
- Nuclear reactors
- Two or more LV solar arrays
- Geothermal generators
You can use water/wind mills to provide power as well, but your quarry will run very slowly if you don't have loads of them. It is best to have the power coming from an MFE or an MFSU because they provide higher voltages and allow your quarry to run faster. Once power is provided to the quarry, wait a few seconds and an orange frame should be built along the yellow and black lines. When the frame is complete, a mining arm should extend down and start to mine blocks. Remember to hook up BuildCraft pipes to your quarry so it can put the mined blocks in a chest.
