Put the input tower and the output tower WITHOUT ANY DRONES, in the input tower put the item you want to demand from other towers or from any source you like and in the output tower put the item you want to give to other towers, so... input tower DEMAND, output tower SUPPLY, that's it, you configure it as you like, if you want it to be remote or not

**PRE-WARNING** there are a couple belts not connected will fix when i can, but be sure to check those, doesn't affect the main functionality but slowly fills up more on one side than the other

**WARNING** imagine this: if you put drones, the drones from input tower will go to the output tower to get the fluids and make a loop from output to input wasting energy for nothing, and if you put REMOTE demand in the input tower it will receive it but if you put REMOTE supply in the output tower it will create a loop, you will request the fluids from other planets and then give them to other planets with REMOTE DEMAND active (not an issue if those other planet's towers have remote supply disabled), careful with that.
