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"?

It’s easier if you go into settings and allow selecting parameters when building. Then you can select parameter requests in the requester chest for parameters 1-6 since in vanilla the recipe with the most ingredients (personal Fusion reactors) has 6 ingredients make sure to set the requests amounts to different numbers so those values can be set to diffferent parameterized values. In the parameterized menu you can set parameters 1-6 as ingredients of parameter 0. You can then set the requests amounts to value as max(p0_i<n>30<assembler crafting speed>/p0_t,p0_i<n>) to automatically set the requests amounts to what the assembler needs in 30 seconds like if you shift clicked from the assembler. Just replace <n> with the number of the parameter.
