... I use Uncommon Logistics Bots to force a Roboport to be empty.
This is the same underlying idea behind the Deconstruction Planner filter for Splitter trick; it's an impossible request that produces a desirable effect.

This works for me because I like playing with Quality.
This does not work in ...

... what logistic requests mean?


Thanks Almalexia, i like your idea but it depends on implementation. I could image a 3 directional toggle (like splitter toggle [left - eq - right]) trash to [planet - both - station] on each space station, affecting ALL trash categories, even beeing able to control ...

Or that same ...

... from stealing all the U-235 that you need to keep Kovarex running? You only put the excess in a logistic chest. Using a belt with a prioritized splitter is an extremely common way to handle Kovarex; that belt is your "safe from the logistic network" buffer.

So let's not pretend that belt storage ...

... to keep 100 iron ore around for internal use, those ores should go onto belts. The extras can be split off to go to the hub via a prioritized splitter.

That's exactly how your players inventory trash slots, or any other trash slots behave if there are no free logistic chests to dump to.

But ...

Splitter filters already support this, so why shouldn't inserter filters do the same?

... at least IMO.


Even then, it's not a guarantee of perfectly even distribution.


If you want perfectly even distribution you can use extra splitter, if you want simplicity and avoid clogged sides on the line you could get the aforementioned inserter.


Also the pickup-position priority ...

... in the same tab as number and equations) could be used to represent the red or green circuit output?

I've attached an example for the input of a splitter where it would be easier if the red and green wires could be attached directly to the splitter, using the red and green signal icons to represent ...

... rod and collector: charge

also there are creative items, that should be cofigureable by wire signals:
- infinity chest: see resquester/buffer chest
- lane splitter: see splitter
- heat interface: set temp & other settings
- electric interface: set sliders and modes
- bottomless chest: on/off

... of inserter outputs


What?
Using circuit conditions the player should be able to switch the output lanes of an inserter similar to how splitter circuit conditions work

Why?
it would allow the player to feed two items on one belt via a single box in ...

tl;dr
A splitter where the output and input sides for each square of the 2x1 splitter are facing opposite directions.
This would help with splitting primarily when coming out of an underground belt, or when two lines heading opposite directions need to be sorted.

Inserters picking up from a splitter only ever take from the output side of it, that I know, it is consistent.
However, this behavior is not very obvious and it rarely actually matters, but when it does, the pickup indicator can be very misleading and lead to dysfunctional deigns that will teach you ...

yeah, that sounds about right! Splitter filter was only 'quality X and above' or 'item of specific quality/any quality' last I played factorio.
to do 'quality X and above for specific item', you could stack two splitters one right after the other, but like, that feels jank.. (though taking a look ...

For loading splitters/belts from mining drills, there is a workaround with circuit conditions:
https://www.reddit.com/r/factorio/comments/1r9dy7v/full_belt_from_mining_drills

Add a belt before the splitter (which is being loaded by the miner) and connect it to the miner. Set the belt to read all ...

... and why. It is possible to recycle only the excess above 55 per minute instead of almost everything with a few extra combinators blocking a splitter in the top right corner, i was too lazy to add.

5) The system must be reconfigurable to any other end ...

Swap splitter priority ui top and bottom

What?
Switch the position of the input and output splitter priorities.

Why?
If a splitter faces north, the input is in the bottom, and the UI input is in the top. And the output on top, UI on bottom. But, the ...

TL;DR
Allow the "No Item" (gray 🚫) signal that appears in circuit-controlled splitters to be selected from the GUI when setting filters on splitters.


What?
When splitters got circuit control a few months ago, this introduced a new signal, "No Item." The only place this appears normally is in the ...

Use case for soft filters:

Multiple parallel sushi belts, with one exit for red circuits.

At present, you need separate filtered splitters for each sushi lane, merging the red filtered outputs after the exit.

With soft filters, each lane can send red circuits towards the exit without blocking other ...

If I understood right, it could easily be achieved with combinations of splitters.
It's general rule of thumb not to add such things, to keep core idea that anything from basic ones and zeroes, even if you had to come up with some 'trick' that has become basic themselves. That's why they don't add ...
