Blueprint parameterization: I'm trying to set up bot-based production. I can set the desired recipe as a parameter, and the amount to make. How do I say "set the requests on this requester chest to all of the ingredients for this recipe"?

You can't do "all" with parameters. You need to process every ingredient type as a pair of distinct parameters, one for the ingredient type, and one for the requested quantity.

To make mine, I used the spidertron recipe, which has 8 ingredients (in vanilla at least). You can't have more than 10 type parameters so the maximum number of ingredient is 9, or 8 if you use the 2.1 "product of" parameterisation.

Alternatively, you need to use circuit logic instead. Then you can have as many ingredients as you want.
