I think that early stage is so short it is not worth programming, but it is just my opinion
I for example never mined by hand more than maybe 100 items and there is a lot of sources under one cell

No. You fill it with full capacity and switching to lower stack sizes when you come near to the filling limits. So first it fills as fast as possible and short before you reach the limit you switch the stack limit to 1 and fill in the remaining items carefully one by one. BTW/Off-Topic: For that yo...

[ But, why do you want to read the content of a single wagon ? I would be really happy if I could read at least the content of the whole train itself :) For example to know how much items more to put into wagon without using filters in train where it is no needed (to allow wagon to have different k...

I can think a number of things that could be done with that and I think when you reduce the number to 1 while filling a train it solves also the problem with the one item left. Using 1 capacity filling could last really long. If you implement signal based inserter's capticity it could be done faste...

How much do you mine and needs to change mining target?
I always run for drills to do everything without me working, so I don't need such features and I believe many others too.
It would be useful, but there are more important things and this wouldn't be used often I guess.

But I was asking about single wagon. Your way will get contents from all wagons, which is not what I asked for

The stack size limit could be a constant or a circuit network signal, and would be clamped between zero and the inserter's maximum stack size. This would be completely flexible but still easy to use, and for example would make moving N items with a stack inserter behave in the optimal way (feed the...

I translated some words to polish. I am programmer and I know a lot of english words, but don't know how exactly to translate them to polish, because we use english technical definitions. But will try to look how it is used in polish universities. Also what is "matching sever"? Sever host ...

I talked about getting info into circuit network You said that getting the cargo wagon content into circuit network would be hard. I showed you that the cargo wagon content is already available, only the train stop can't read those values :) But how can I get this data into circuit network fo examp...

Like that it can work too I think, but not so nicely (can block inserter if for example creating iron plates ends). But I don't see any builds that wouldn't be possible compared to current version. Current version allows only picking max inserter's capcity anyway, so maybe max what had to be changed...

This one could be pretty hard to do anyway. I mean you would have problems with loading the train anyway (as you don't know how many free slots wagon have). Also if it is connected to the train then all wagons would count in. It would be problematic to create system that works for any number of wag...

Okay, created the fastest solution possible (but got some cons). It needs enough items to get full desired amount.

Examples? For example we want to pick 3 iron plates for chest. Iron plates goes straight from Furnace, let's say 1 plate for 2 sec. Then it will never stack to 3 amount at once without loop. But using my idea it is quite simple. We check "what we need in box" and tell that to inserter. In...

Oh, I always got too much items, so I guess I got another perception
Did the test, should work I think. (edited last comment)

I think my solution will work as this magazine can store a lot of items. Ofc on start it will not work, only after magazine gets desired item amount. "How will bots bring the items from E to S." It will bring needed items from E to S using W magazine :p I will do the test and tell if this ...

Could be both, because both functions got different use cases. Tagging is better than content reading in identifying, because it will identify the train even with emptied wagons. And it could be both, because reading content from wagon's inventory will not affect train's tag signal which is not item...

It would even work with regular filter inserters... and each filter signal specifies its own amount of holding items. So it could look like that for example: Filter Signal 1: Iron Ore = 3 Filter Signal 2: Copper Ore = 1 Filter Signal 3: Stone = 2 Filter Signal 4: Unmapped Filter Signal 5: Unmapped ...

... how it helps to solve the problem mentioned in this suggestion. I would also say it's a bit off-topic. :) If correctly placed it will just change robots route, because new magazine will be avaible for robots. Using firs post map: S produces for example silver plates. W got this new magazine, ro...

Having Stations report a trains inventory to circuit network would open a lot of possibilities for smarter train loading. This one could be pretty hard to do anyway. I mean you would have problems with loading the train anyway (as you don't know how many free slots wagon have). Also if it is connec...

I think tagging trains using signals and it's amount could be nice. For example in the game we create trains for different purposes. While having universal stations it can be dificult to guess what to load what to not. While having empty filters in wagon, wagon supplier can load items that we don't ...
