Modulus Factory Automation – Production Ratios Guide

One of the most important skills in Modulus Factory Automation is balancing your production ratios. A ratio is simply the number of each machine type required to run a production chain without bottlenecks — where no machine is idle waiting for inputs and no conveyor is permanently backed up.

Getting your ratios wrong is the most common reason new players find their Neural Monuments stalling. Either an upstream machine cannot keep up and the Monument starves, or an overproducing machine floods the conveyors and causes a gridlock. This guide to Modulus Factory Automation production ratios covers the core machine pairs and how to scale them correctly.

The first ratio to master in Modulus Factory Automation is Miners to Furnaces. Based on community testing and the official Tips page:

Rule of thumb: Always build in multiples of 4 Miners when adding Furnaces. Adding 3 Miners to an existing 4-Miner line will leave the second Furnace at 75% efficiency.

After the Furnace, your Base Cubes feed into the Cutter. The Cutter and Painter generally operate at similar throughput speeds in Modulus Factory Automation. The Stamper, however, is slightly slower and is often the bottleneck in stamped-module production chains.

Approximate ratios based on community testing:

Important: These ratios assume your Neural Monument's required module uses one of each shaping step. For modules requiring only Cut + Paint (no Stamp), remove the Stampers from your ratio. For complex multi-part modules requiring two Assembler inputs, you may need two parallel Cut→Paint→Stamp chains feeding into each Assembler input port.

A single conveyor belt in Modulus Factory Automation has a finite item throughput capacity. When a production line exceeds this capacity — for example, eight Furnaces feeding into a single belt toward the Cutter — you must split the flow across multiple parallel conveyors.

A good rule of thumb: one conveyor belt comfortably handles the output of up to four Furnaces. Beyond that, split into parallel lanes.

Sorters are your best friend for maintaining ratio integrity on shared belts. When multiple item types (different colours or shapes) travel on the same belt, a Sorter placed before your processing machines will filter each type to the correct machine — preventing the cross-contamination that ruins module quality.

As you progress through Modulus Factory Automation's Neural Monuments, the module requirements scale dramatically in both complexity and quantity per minute. A Tier 3 Monument may require a production rate 10× higher than Tier 1.

Before scaling, audit your existing factory with this checklist: 1. Is any machine idling? (Upstream bottleneck) 2. Is any conveyor permanently full? (Downstream bottleneck) 3. Are your Sorters correctly filtering all streams? 4. Is your Warehouse buffer large enough to handle demand spikes?

Address bottlenecks one layer at a time, starting from the Monument delivery point and working backwards toward the Miners. This reverse-audit approach, known as the "demand-pull" method, is the most efficient way to scale your factory in Modulus Factory Automation.
