Thank you!
I didn't understand the logistic request from the silo, but I did it from the space platform and it worked!

Hello Everyone! Good Space Age to you :)

I am trying to insert Processing units in the rocket silo (more precisely a stack of Uncommon ones).
But the inserter does not move...
I guess it is because the processing unit is in the recipe for the rocket (Both rockets are already built).
But I want it ...
