I'm trying to make frag grenades (c12). This is my first factory so forgive any ignorance. I have plenty of resources in the resource hopper. I placed the crates of the other two components into the hopper. I start the hopper and a minute later it stops and says that I don't have enough Light warhead mechanisms to create the object. So, I take all the crates out, empty a crate of 25 and put them in there individual and I get the same message.

What am I doing wrong?

Same serial # on the ones your using and the scematic?

ahhhhh! nope

I used a different serial number on the schematic. Thanks
