Minetweaker and ic2

Now this was a fun reading comprehension.

With Minecraft 1.7, IDs have been removed, so there isn't a list of ones that IC2 uses.
Instead, it works that each block/item has a name, meaning with Minetweaker a macerator would be <IC2:blockMachine:3>.
In order to see the name of an item, you can hold it in your hand and type /mt hand in the chat, which will tell you it's name.
The Minetweaker wiki tells you all this (pretty much) - http://minetweaker3.powerofbyt…age#Tutorials_.281.7.X.29
