Compact 1x1 loaders that use electricity. They are able to use separate filters on each belt lane, and can stack items on belts if stack inserters are available.
For unknown reason sometime the stack is not complete I often have 30 instead of 32 items on belt. (this will a full chest of item so it's not a problem of input)
Possibly (probably). The stacking is part of the base entity that I'm making available, not something I'm creating. Are you using belts faster than Turbo (60 Items/s)?
No turbo belt from Space age. Nothing special, did you not see this problem before in your game ? Should be simple to reproduce a chest that have one output loader and 6 input loader of stone, don't know if chest full or half full matter
I have been able to replicated this as well as some other odd rate anomalies that are defendant on the rate into the chest. I'll need to flesh out the testing a little more and file a report with wube. This looks very much like an engine thing.
No, this is not fixed yet. See: https://forums.factorio.com/123836. It is related to a mechanic in the game engine that may or may not get resolved.
As I interpret the statement from the dev, because loaders do not have a temporary inventory of their own, they cannot gather from multiple inventory slots. So, if the one slot they are pulling from doesn't have enough to fill the output, it can't.
Odd. I seem to have got it "functioningly" working by simply telling the loaders to wait till the attached chest/assembler has over 8 items before trying to move. https://i.imgur.com/3SWLeIY.png
It probably shouldn't require this, I understand that, but it does work...
