I follow the instructions, but the plan does not work

Construction plan*

Which deployer did you use? There are two of them in the latest version. They look the same, but they have different names and they have different control signals.

I'm having the same problem, nothing is building.

What I'm doing: I've tried both deployers, but nothing works.
I put the deployer with a red cable and connected a combinator with robot builder signal = 1.
In the deployer itself I put a simple blueprint with cross-shaped walls.
Nearby there is electricity, a robot station with robots, I have robot builders in my pocket, a storage chest with walls.
What am I doing wrong?

Basically I don't need any super clever schematics, I just want to build trains from the blueprint when the system is signaling that there aren't enough of them. (I already have this system)

If you are using old setups, then check the mod options (for map). In recent versions, the default signal for construction is "0" (zero).

thx a lot, it works for me
