None of the buildings in this mod seem to be capable of circuit connections; I know at least for certain that none of the turrets can receive them, and neither can the miniature assembling machine or the machine press (and I assume all other variant assembling machines will be incapable as well). I haven't tried the belts or inserters but I wouldn't be surprised if the versions added by this mod are incapable.

If it's relevant, I am not playing with Space Age.

Heya,

The only entities that have proper connections should be the warehouses. Aside from that, the new electric poles should support them, but they may not line up correctly. It's honestly just really low on the list to do all the electronics for everything since its use by the very tippy top percentile of players.

At some point they will have a proper pass, but until then, hang tight.

Cheers!
