TL;DR
Let us read space request from combinators regardless of the planet having the supply.What?
Currently set the rocket silo to read station request with logic, which is great, but kind of useless as it only allow one to read it when it would already begin sent to the logistic network. We should be able to read the logic line, while the logistic network doesn't make the request, since the planet doesn't have enough in stock. That is exactly what you need to make the factory start to workIf you request like 2k belts, and you have a factory that makes belts, but if you don't have the entire rocket worth of items in supply the logistic, the request won't be sent to the planet, so one can't make use of the selector combinator to ask the factory to build one rocket worth of the requested item. So one is stuck with having to always keep at least one rocket worth of every single item it might get sent to space.
That would easily be fixed if the logic connection could read the request, even if the planet doesn't have it in stock, that is exactly why one would want to ready with logic, otherwise there is no reason to have the logic for reading the request.
Been able to read the station request, combined with the selector combinator would allow us to make the factory start to work on demand to fulfill that particular request, by just attaching the output of the selector combinator to a buffer chest set to set requests on logic.
Well, we can still do this, but it is just useless, as at the point the request gets read, bots will already bring it to the rocket anyways because it also get send to the logistic network already.
