You may not have enough ore. This is because if you get two or more in creative the game will treat it as an infinite stack. However, the Assembler has a hard time dealing with infinite stacks. You should try to use this technique:
 * 1) Get at least two of the ores you want.
 * 2) Spread them out in the Assembler like this

3. Then combine all of the ore in the Assembler, and then it should work.
