Does this work with modded assemblers?

no, but I can do it just send me a modded assemblers you want, or a mod that they are from

why not add a ui that lets you place the inserter in the slot and it takes the stats from that or something like that then you dont need to code in every single moded inserter

moded inserter?
my mod doesn't add inserters only changes assemblers so they spew items like recyclers so it is instant
I still need to add code to every machine that does this so I need to know what mod its from so it would be balanced

Your idea with UI slot actually requires much more coding

Just tell me what modded assemblers/machine you want, or a mod that they are from <3

I use Bobs mods... some assemblers that work like miners should be interesting...
My question is, they stack items on belts as well?

Yes, mostly when output has more then just single item
but if you use some circuit logic (perhaps stopping a belt) you can pull them any number of them stacked
I could just add a auto script but I think this way is more fun

Great, also, no need for scripts, I agree with you with you on last part.
Can you make assemblers for Bobs? Bob also have electronic assemblers, they are mini assemblers that only produce circuits.
This will remove almost half of inserters on assemblers... if you manage to make something similar on the Imput as well (like an invisible, or even visible, inserter that is embedded on the assembler), it would become even greater, but this is probably asking too much.

I will later make a separate mod for modded spew machines from different mods,
Can you give me a link for what mod this or the author (I don't wanna mod the wrong mod)
I want to keep this one just for vanilla

Well, already told you several times, but you probably missed because the name is a bit silly... Bob's is a collection of several mods made by... well... BOB.... and all mods of him start with "Bob's"
Here is the specific mod that add assembly machines.

You should check his other mods... sadly, we lost him to Timberborn a few months ago...
