I've found that I can't craft a machine block. The common recipe for a machine block is an "empty circle" made of refined iron.
But if I try it, I craft a YELLOW PIPE WIRE (Item ID 4072) from BuildCraft, which is supposed to be crafted from a Assembly Table.
I've tried to look for the Machine Block in Not Enough Items, but when I use the U key on the refined Iron, the machine block doesn't appear on the shaped crafting list. And if the search the block for it's name, I can't find it on the list.
What I think of, is how will I be able make machines from IC2 in a survival world?
I can't go into Creative always... and I'm not sure if this is caused by the beta.
