Welcome to the Multiblock/Multipiston page.
The multiblock looks like a smooth andesite block, with a hole in each face. Crafting the multiblock requires 3 stone, 2 blocks of redstone, 3 pistons, and the build tool.
Place the multiblock beside, above, or below the blocks you want to move. Then right click it to open the GUI.
You will see 4 blue arrows, a + and a - with Range: and Speed: in the center. The arrows refer to the cardinal directions, Up for North, Down for South, Right for East and Left for West. The + is to raise and the - is to lower. The Range: is 10 blocks and The Speed: is 1-3, 3 being the fastest.
You will need to left click on one of the arrows or +, or - and it will turn green. This shows the directions the blocks will move when activating the redstone. Then right click on another arrow or + or - for the direction the blocks will move when the redstone signal is off. (this is typically the location of where the blocks are currently in the build.)
Note: All blocks must be the same in order to work.
Note: There must be enough room for all the blocks to move or it will stop.
