Oh, well, the recipe combinator works a bit differently than that...
You input a recipe signal and it'll output the ingredients, it can't read it directly from an assembler.
A good point is though that there's currently no way to read the recipe from an assembler. I can imagine that would be quite a useful feature.
I'm not sure what would be the best way to implement it tho. It might work to make it a second function of the recipe combinator but I'm worried it would be too confusing (it kinda is already).
If you have any ideas on how to do this or think that I should change something, be sure let me know ;)
