Behaviours with smart belt is better describled with a video:
Factorio - 2025-06-02 13-48-16.mp4

There are three situations:
1. red belt, without red underground belt in inventory;
2. red belt, with red underground belt in inventory;
3. green belt without green underground belt in inventory and ...

What & Why
We can upgrade existing blueprint by opening it, click button on the top (upgrade this blueprint) and select an upgrade planner to instantly use it.
But many upgrade changes need improvised upgrade planner for specific design, so it will be good to be able to setup a temporary upgrade ...

What & Why
It sounds complicated, but is very easy:
d41e668a5459913e811004ae5f067f47.png (Only iron ore can be placed here, calcite can not)
I can't put calcite request(or actual) item inside this slot, but I want to put it as input. Just move my mouse right would work.
Problem: I have broken ...

What?
For example, we can:
1. Higher quality cargo bay have more cargo input/output slots;
2. A technology to increase cargo input/output, or traversal speed;
3. Just increase the base number! I think it's a bit low for optimized setups, making carefully design a space platform less meaningful and ...

What?
It's actually about "blueprint only machine settings". I want to paste a set of wires/settings/recipes, but for different module setuped machines. Currently when I paste blueprint with no module on existing machine, it removes all modules from that machine.

Why?
The default is ...

What?
Some improvement of item request, for example:
1. don't cancel remote item request when change entity quality. (or allow control whether cancel)
2. blueprint remote item request (or allow control of them)

Why?
Remotely put item ghost inside entities are a great feature, but they behave a ...

If you feed all 3, the crushing recipe is selected (it's the recipe that's selected, not the crushing for the given asteroid). This is also unexpected. The crushing for the asteroid should be selected, since it's more to the left in the GUI than the recipes. There seems some internal tweaking ...

The whole problem is, that this creates a hazard.

Yes, definitely. This is what lead me to this post and took me hours to fix. I edited original post again to include my current working solution: Add a block signal to completely prevent crushing recipes from happening.


It might work 100% if ...

The whole problem is likely caused by a simple mechanic, that you might not be aware of. When you send a signal of asteroid to the crusher, it will set it's recipe to crushing of that asteroid:

Thanks for your reply! You are correct about this.

Though it feels "unsafe", it is intentional ...

I think the difference between working and not working version is the wire are inverted green<=>red but the settings inside the left decider combinator are "red" in the 2 versions.
Yes, that is an oversight when testing, and that's why I can consistently get a not working version XD
However, I ...

Currently Problamtic Setup
When making an asteriod crusher recycling design, I came to this weird problem that instead of setting the recipe to reprocessing, it sets the recipe to crushing.

+1
I also find it surprising that this is not already in factorio

What?
Add a (infinite) technology to reduce cargo landing time. Also possibly add a (infinite) technology to reduce space platform cargo send interval.

Why?
One idea just came about my head that "how about build everything I can from space", but instantly I hated that whenever something is ...

That will cause trouble if you pin in the description something that is not contained in the blueprint : "this combinators trigger the put in the norther outpost".

One way i found to alleviate the need for this is to use numbers for combinators, : " 14 : this combinators trigger the combinator 12 ...

When deconstructing some specific asteroid collector the server and all client crashes with Unexpected error occurred. The only some of the asteroid collector have this problem. Mods are enabled(see attachments).

Important info in log:
Error AsteroidCollectorNavmesh.cpp
unregistering a chunk that ...

What?
Allow add a pin to other (circuit) entities or locations inside combinators' note, more: support blueprint(to pin corresponding entities inside the blueprint).

Why?
Notes are generally a good thing, but their use is limited that they can only "describle" the intention of this entity and ...

What?
Set an additional offset for blueprint book, that affect all absolute grid blueprints in it.

Why?
When do I use absolute grid or relative grid snapping? I use absolute when the design "absolutely" requires to align with world coordinates(which is rare) or with other aboslute blueprints ...

What?
Add a wait (for n seconds) condition for triggering train interrupts

Why?
Currently there is a "n seconds passed" condition for train leave station condition, but not for train interrupt conditon, like: after n seconds no other destination, trigger this interrupt.
This idea originates ...

What?
Allow renaming(changing) target stations in train schedules.

Why?
2025-05-01_16-04-03.png
The target station is not changeable after it is set. If I want to change it, I will need to make a new target station and set all conditions accordingly. The snapshot is a train interrupt, regular ...

What?
Add QoL editing features to train schedules, interrupts and circuit conditions like copy/paste/undo/redo, not just whole entity, but copy/paste on an "one line" basis.

Why? 2025-05-01_16-00-02.png
Conditions in train schedules or circuits is now used more boardly and complexly, so adding ...
