Okay. But computercraft isnt my thing so i made another solution. the 1st is a deployer facing air block what the blockbreakers dug and behind that aur block is a wall.. make it so that the deployer deploys chunkloaders ( put at least 8 in it in the bottom right slot ) and 5 blocks down a redstone frube 3 blockbreakers so that they can catch them again und give it the deployer back.
2nd is like the same only diffrence is the deployers face is facing the block breakers face but 3 air blocks between them so its deploying in the air and the block breaker is catching it.
i wish i could show that easy in a picture.. but i cant post some rigth now..
