Smart Splitter

[solstalynn]

Here is how I thought the smart splitter was supposed to work: 1. Items enter Splitter, 2. if item =A then it goes to A, if item = B it goes to B, if item = neither, it continues on.
This is what I have discovered to be true, instead: 1. Item enters Splitter, 2. if item=A then it goes to A, unless it is an even count of A, in which case it continues on, if item =B it is sorted into B, unless it is an even count of item B in which case it continues on. and of course, if it is neither A or B it continues on.

input------> -Unspecified->

B
Is this a function of the smart splitter, or is supposed to split all. Also, this might be why the overflow splitters are not functioning properly.


My only solution is to specify each output and then merge the unspecified output with the input for a dirty fix that has the turn around running down with each additional pass.

If your A-B output conveyors slower than your input they are gonna exit through the 3rd output if it's set to overflow. If you set the your 3rd output to any undefined then items A and B will clog your conveyors when their output conveyor is full. If you're using smart splitters for machines I don't recommend it. They're more useful for sorting items into storage containers.

I was and am using them for bio-matter sorter. When it was only 3 there was no problem, of course, it was when I increased to sorting all bio-matter for bio-fuel that it became a problem. Which was solved by running the stuff through the sorters multiple times until it got it right. Simple loop with a conveyor merger.

This is an old thread, but I just ran into this same thing and there's a better answer than a merger loop, which is messy - Set the output you want to the proper item, then set the other output to "any undefined". This worked nicely for my storage "mall" for all the items I want to collect to use for building.

The caveat to this is that the Overflow doesn't work as well. I had to have each smart splitter setup the 3rd output to overflow, then merge all of those into a feed that goes to my sink.

I had built a multistorage sorting/overflow/shredder system and noticed: If the smart splitter is configured to "good A left", "any undefined straight" and "overflow to the right" (leading to the overflow to shredder belt in my case) everything is getting considered overflow, once things are backing up. That led to items being overflowed and shreddered without even reaching their destinations sorting splitter.

This mostly happened when some bulk goods like quartz sand arrived and overflowed, blocking the overflow line somewhere in the building so other overflows before the quartz overflow are getting blocked up and backed up to the next earlier smart splitter and so on, resulting in a sorting mess.

I resorted then to a much easier design, where everything runs in and every smart splitter is configured to item X to container and everything else continues as overflow through all the splitters in the storage building (all setup for different goods to sort out and overflow the rest). So once containers are full or things didn't get selected they'll finally arrive at the exit and are going to the shredder. The whole belt inside the storage building is roughly 600 items long, so the downside is of course, that once most containers are full things will run the whole course without any use. The upside is, that once you take things out, they'll automatically refill and overflow without the need of any interference.
