Yes, replace the signals between W1-3 and ? with chain signals, but leave the normal signals between ? and S1-2. This will mean that trains will only move leave W1-3 when it can enter the correct station.

You cannot currently. The red/green tick boxes on the outputs control where the output gets the number from.

The only way to get ingredents and contents separately is to have two assemblers.

A couple of general suggestions.

Rather than immediately canceling the craft if the required ingredients drop below the required level, have a delay before canceling. The length of the delay will probably need some experimentation.

Or have two different checks for ingredient levels, an initial ...

Use a constant combinator to feed in the maximum value, then have two deciders one for less than the maximum which outputs the original item count, the other for greater or equal to the maximum which outputs the maximum input.

Another possible solution would be to add an 'ingredients of' option to the decider combinator.

It is possible with two decider combinators. Using red wires link the outputs of both combinators, to the both inputs of the combinators. Using green wires link the inputs of both combinators together. Then also link the outputs of both combinators together using green wires.

One combinator setup ...

Is there an easy way to stop the assembler from being over-filled, so it can't clog up and stop?

Having an inserter remove all of the outputs isn't a great solution as all of the unwanted items would need to be sorted & moved back into their own storage or supply lines. There could be many ...

Already done. To quote from FFF #395: "We also added the ability to set the priority using the circuit network."

The problem I'm running across is that I want to design a very large version of this kind of automated rail station, with many items that can't possibly fit on a single train car (I want to use one to supply an 'everything' mall, and another one to supply cargo rockets in space exploration). If ...

Will there be a way to handle unknown items with generic item interrupts? For example, being able to say "if you can't find a stop to bring this item to, take it here"? That would be extremely useful.


In the FF they say that "Trains will 'No Path' for stops that don't exist." Then I would think ...

I currently use skipping for my ammunition supply train, in a way that certainly can't be replaced by stop limits, and I don't think (though I may be wrong) can be emulated by an interrupt. The supply train carries enough ammo, oil, repair kits etc. to top up three wall sectors. So its schedule ...

In Friday Facts #373, they said "Since we know where we are and what is the goal, we can start to approximate the date of releasing the expansion, which is planned to be about one year from now.", which will be around August 2024.

And they have said that version 2.0 will be released at the same ...

Other larger chests. The more slots the chest has, the more processing power is needed to add or remove items.

Left lines and right lines are independent. It takes from left belt because it is the only one to provide items on the right lane.


If "input priority" refers to the side of the belt and not the side of the splitter, why does the yellow chevron move to the right or left side of the splitter ...

You lot, do realise that we are going to get this on a update on the first of next month :->

Rather than disabling the iron ore pickup station when there is not enough ore, use the circuit condition to set the train limit on the station. If there is not enough ore set it to 0, otherwise set it to 1.

That will cause the trains to wait at the previous station until there is space for it.

What I would love to have is a coffee table art book with all the various art plus the FFFs edited into a history of Factorio.

I read it as he wants to filter the output of the read train contents by wagon. So he could say tell me the contents of the first wagon of the train.
