DaveMcW, this sweet, you got me! Now it's probably a way to do a redesign (too many items are transfered inderectly in my opinion), but I don't believe it can be even more compact than those 16x16. Just a little bit different and that's it. I like to optimise like that, but I wonder if there's a poi...

The same in a 16x16 and T1-4+Lab in 16x18. Probably there's still a room to miniaturization.

Even more compact design with 10x11 footprint. ;) The iron and copper inserters are wired to a smart chest. Iron flows while gears < 10, and copper flows while copper < 10. This is needed to stop the cargo wagon from filling with raw materials. Very nice! Though you need a little bit more research ...

Compact tier 1+2 design with 9x14 footprint for early stages. 1 green + 1 red flasks per 6.66 seconds. Had to use +20% production module to attain balance between green and red production, but at early stages this can be simply ignored. Science labs can be put separately or right on top (3 labs max ...

I saw the post above and decided to try something similar with the minimal footprint challenge (without robotics). The result is much more chaotic because I cut out second gear AM and had to reroute the whole thing due to that. Also I replaced two wire AM1s with one AM2, which is quite sufficient en...
