Splitters, filtering and halving

[Sir Prometeus]

Is it possible to achieve this in vanilla?

One belt with products A and B (A left, B right) enter a splitter. The splitter allows product B to continue undisturbed through the main belt, but product A is halved between the main belt and a secondary one

The reason behind this is separating the products I need from the main bus towards secondary belts that feed factories

Quite often, when I set a filter in a splitter, the other product I didn't filter stops passing through the main bus

Here is a screenshot of what you can do.
P.S Product B is stone furnace product A is the landfill

Split the 2 resources, split the desired resource a second time, combine both products again with a 1 lane balancer.
Additionally set a unfiltered output priority to go down the main Bus so your bus is always stocked with items for more important assembly lines

^this, except i would use a splitter output filter on the first splitter to filter only the product out that he wants to split off

I still tend to follow the philisophy of "make so much that it clogs both belts, then you don't need to worry about the ratio."

The brute force approach to logistics :)

This screenshot tells the problem I'm having with filters in the splitters. The makeshift solution of using two splitters would work, but I would need to resize the bus and some other structures.

I wish I had a better GUI that allowed me to set different filters for each line. In this case, the leftmost line would have a simple output, whereas the center line has no filters

ok so i see a few redudant items in that picture. 1st off the splitter pulling copper out if you to that like 5 belts earlier and move that entire belt to the left 1 you can split the copper to the right to make wires.. leaves you with just teh iron going up.. and then you can turn it to the left to output. then you are left with just 3 going up at that point

its so much easier to compact that to just 3-4 lanes total also why put reds on that to just splitter them off its so much easier to just put them on a belt by themselves and undergorund it. jsut needless splitting to just split stuff

[Name Lips]

It looks to me like you're trying to build a tight, compact bus.

I don't do that. I figure space is one of the few infinite resources in the game, so why not use it?

What are you going to do in 10-20 hours, when you realize you want 4 or 8 full belts of iron?

[astrosha]

IMO, on a bus, both lanes of a belt should be the same product. Need to move another product, add another belt!

Split belts like that are for stuff being peeled off of the bus, to feed machines. If those machines are putting something onto the bus, however - like the red circuits in that screen shot - it should be a full belt worth, both lanes.

In reply to all of you. I'm still improvising. Still I haven't created a modular megafactory. At best, in another game, I reached the logistic bot tech level, and that helped a bit with the combination of blueprinted zones (like the solar pannels) with the more or less ad hoc use of bus lines. The bots basically filled the gaps created by a non-optimal belt configuration.

In the picture, the left output will be used to manufacture blue science packs. In this game, I haven't bothered with automatically feeding the iron/steel ovens and I want to revamp the whole area with electric furnaces.

The concrete wall building area is even more primitive. Recently it has been electrified, but until then, it was working with steam drills and inserters. The enclosure isn't complete yet, but thankfully I already have oil feeding the boilers.

(There's a reason behind all this. My only coal deposit is very small and I think it will be depleted in the near-mid future, so that's why I'm not bothering with something permanent like belts feeding the ovens)

4 lanes of each primary resources(iron, copper and Green circuits)is the minimum of lanes you should go for. An example:

1 tier 1 iron gear assembler takes 2 iron plates each 0,5 sec, while crafting at half the players crafting speed(crafting at 0,5 speed). One full yellow belt can support a throuput of up to 13,33 items/sec(6,66 per side).

So you have one gear assembler tier 1[((0,5 sec(craft time)*2 ironplates)*0,5 crafting speed]= 2 iron plates/second.
So as you can see above, just having one iron gear assembler tier 1 working on our science pack 1 production will take 1/3 of your total iron plate belts capacity, add in another 1/sec for each green circuit maker you have and your single lane design falls apart quicker than you might think.

Regarding the power, you can either go for solid fuel made by crude oil products(was light oil the best for this?) or you can go support your power network with solar, even if you don't have accumulators yet(wich you should have according to your picture showing red circuits being made).
