Nice! It appears that the final splitters somehow break compression though. In my tests the leftmost output belt has holes quite often. I've rearranged the splitters to start merging from the extra 4th belt and it seems to compress the belts perfectly: 0eNqtmNtu4jAQht/F10kVn8LhVVZVFcBlrXUSy3aqIpR3X4...

I've found the second link you gave when looking for a way to test for mods, thats how I learnt about active_mods in the first place... The page is very vague on how active_mods works, and doesn't specify anything about how it can be used other than to just generate a list of mods. Quoting the page...

Slightly smaller case using vanilla loaders and infinity chests:



The top left splitter does not preserve compression.

It's a decent setup. You could try to fit some more power poles to power both beacons columns from inside. I'm not sure what you mean when saying "most efficient/fastest smelting setup". It's possible to make longer setups smelting more than one input belt, although they likely will be a b...

If at some point a logistic request can't be satisfied because the requester chest is filled with some other item, it won't be satisfied after the chest is emptied. Steps to reproduce: 1. Place a requester chest limited to a single slot and requesting some iron plates. 2. Put some other item into th...

This also happens with underground belt entrances, which also fits the "not a bug" reasoning. What is strange is that it happens pretty inconsistently. Sometimes the inserter may work successfully, but in another copy of the same setup it may start failing to pick up any items. Here is a b...

Edit2: I had a look in creative mode, I don't see any gaps in the output belt. It outputs just under 2.4k/m, the 5s statistic seems to oscillate between 200 and 199 plates, with 200/5s being the maximum output of a blue belt. So I think it is producing at very close to maximum blue belt output. You...

Not sure how original this is, but I've made a rather space efficient smelting design: blubelt-compact.png H4sIAAAAAAAA/72Z34qrMBDGX2XxWqGJf2pZfJbF1ewSsFFiPLSI736i7tlDtaaTdOxVwcavM7/MfEmZsn6r6iKv3j6yngnFFWdt1vciP7PM+2R5UQvPb+pW f1GLrL9kATn51yyIBp8rdh7Xjp+Z1zaMlcG5LruKBaHnF3UnVEaHYfCNagmqWoiqdsBUO2KK...

Below is a design for productivity + speed beacons based smelting, which outputs a blue belt of iron/copper plates using 13 smelters* http://i.imgur.com/IrjgeFf.png Hi vanatteveldt, I think your first setup has a problem: the bottom 6 furnaces all have output on the left side of the final belt and ...
