Labs & Science Packs, to get them automated running from HUB Belt System.
Blueplan for 24 Labs, including Belt System with 2 lanes, 2 Sides each lane and mixing What to insert into lane. This means, this belt systems uses up to 7 different Science Packs on only 2 Lanes.
Used Extra Mod: Lighted Electric Poles. Exchangeable with normal Electric Poles.
Used mod "Side Inserters" and Factorio Version > 0.15
HOW TO: Use the Big Electric Pole to determine, which Science Pack needed to be produced. Material Saving! Adjust by setting up Constant Combinator Signal "A" to a matching amount. Default: 150. Then connect either the Green or Red Circuit from the Big electric Pole to the factories found in the book. I normally use as connection the last belt of the Output from the Blueprint. Then set the Enable Setting to the matching Science pack and > 0. Or use the Circuit Connection on the inserters, that take the Science packs out of the Assembly machines. Or connect it to the Input Belts. Every Posibility has positive and negative sides.This will do it all.<BR><BR> Example: <BR>For the Red Science packs, connect the last belt of this Blueprint to the Circuit network (red or green). Set the Enable Checkbox and put the Signal to "Science Pack Red > 0". Thats all you need to do.
