What exactly do you mean with "[not] reliable"?brunzenstein wrote: Sat Jun 28, 2025 12:33 pm I tried the -750 with one reactor for several hours, but it didn’t work out for me at reliable as with four.
There is one flaw in your blueprint. You configured to set stack size with signal S, however you don't provide any signal S, so its value is 0. Setting the stack size 0 is the same as setting stack size 1, so it works, but the correct way to do this in this setup is to not set the stack size via circuit but instead set the "override stack size" to 1.
You also don't need to set any filter. The only thing an inserter will insert into a reactor is a fuel cell.
There is another real error. 2 steam turbines behind 2 substations in the top and bottom center are not connected to steam.
And there is a potential blocker for not inserting fuel cells. The burnt up fuel cell counts as fuel, so as long as it isn't being removed from the reactor for some reason, it is an item with amount > 0, so the EVERYTHING <= 0 will not trigger, so no fuel will be inserted. This can be corrected by adding a (burnt up fuel cell) = -50 to the constant combinator, so until a full stack of burnt up fuel cells is accumulated, insertion can continue. This will never happen nonetheless, as long as you properly remove burnt up fuel cell and don't let them accumulate. You need to recycle them, and you need to add enough centrifuges to recycle more than there is produced by your reactor.
