Modular low-volume Universal Assembler.
High density<sup><a href="https://factorioprints.com/view/-LJ2A1S7ciqdngYf-HnR#notes">1</a></sup> (14 tiles per assembler) low cost (<img src="https://wiki.factorio.com/images/Fast_inserter.png"/><img src="https://wiki.factorio.com/images/Assembling_machine_2.png"/><img src="https://wiki.factorio.com/images/Substation.png"/>) and easy to re-configure.
Perfect for custom, intermittent, or shifting production loads such as construction and resupply trains.
Usage Examples
Installation Instructions
The modular system is based around a power and signal bus. Each substation-aligned bus tile supports 24 assemblers and leaves symmetric 2 x 3 access ports for feedline belts of intermediate products.
The blueprints are used as follows:
- UA power & signal bus routes all necessary signals and connects to adjacent horizontal tiles.
- UA controller and status display (max one in network!) does several things.
- It connects the demand (green) and work-queue (red) wires.
- It displays progress bars for the requested items being built (left, cyan) and logistics bot load (right, green-yellow-red.)
- Logistic network coverage.
- Feedlines snake blue belts through the 2 x 3 access ports and deliver in-demand materials to the center of the logistic grid. By using higher priority chests than on the edges you can optimize bot pathing a little bit. Feedlines are very optional.
Once you've got a power and signal bus, you can add assemblers in groups of 4. Configure each one, set inputs in the requester chest, and set the constructed item as a condition on the output inserter. The last step ensures only items requested via the circuit network<sup><a href="https://factorioprints.com/view/-LJ1yGYd0Rex-FPTqnnk#notes">2</a></sup> get built. Once an assembler, requester chest, and output inserter are configured they can be constructed from blueprint by robots on top of the "UA power & signal bus" with no player intervention.
The signal bus carries two signals:
