Probably Stolen modules: machine effects and list

What Probably Stolen modules change

Probably Stolen modules change how a machine works by affecting its recipe, output, efficiency, performance, quality, or specialized functions. The Machines and Modules collection says efficiency, performance and quality are three different dimensions, so you pick modules by the production problem you have. Machines and Modules collection

Ordinary modules carry a percentage bonus to efficiency, performance and quality, plus a tier. What each stat does depends on the machine it goes into, and the percentages are not fixed per module name, so the name alone does not give the effect. Module reference

The stat modules are Performance, Efficiency, Quality, Eco, Fineness and Overclock. The overview gives example values for Eco, Fineness and Overclock, while the specialist modules are described by the collection and item pages. Modules system overview

Probably Stolen module list: machine-specific effects

Metal Printer and Computer Numerical Control modules form a paired route for particular chips. The Metal Printer Module enables chips that need metal printing, and the Computer Numerical Control Module enables frame and gun-part chips when paired with it. A Steam thread asks where to get both modules; one reply says the retired gunsmith who visits once a week may stock them. Steam discussion

Hydroponic modules change what specific crops produce or how they are handled. The examples are more Nutrifruit, Dream Cap turned into Meal Cap or Nightmare Cap, Kotton Fiber woven into fabric, and Hydroreed stems harvested as water filters. The effects are crop-specific rather than one shared bonus. Machines and Modules collection

Chemical Equipment Modules can improve the Blender, Heating Plate, and Chem Finisher. The collection gives a base value for the module but no numerical bonus for these improvements, so the table lists the module without a bonus figure. Once installed, it needs a module extractor to remove. Machines and Modules collection

The Junk Processing Module converts 6 Junk into 4 Scrap Metal. The Blast Furnace Module changes the recipe from two raw materials for one ingot to three raw materials for two ingots, and the module reference describes it as 3 input for 2 output per night, at lower purity. Module reference

The item page adds that the Blast Furnace Module reduces the purity bonus from one quality tier and is not stackable. Blast Furnace Module item page

How stat modules trade machine performance

Eco, Fineness and Overclock each trade one stat for others. In the overview's example values, Eco gives +32% Efficiency and −16% Performance, Fineness gives +25% Quality, −8% Performance and −15% Efficiency, and Overclock gives +36% Performance and −44% Efficiency. The overview says these are examples shown in a video, and it warns to check your battery supply before fitting an Overclock module. Modules system overview

The Neural Core has a fixed stat profile: +100% performance, −100% efficiency, and +50% quality. Those three figures make its tradeoff explicit, unlike ordinary Probably Stolen modules whose percentage effects depend on the machine. Module reference

Specialized modules can provide recipes, production switching, or filtering functions, and remain effective even if all three attributes are 0. The machine-modules term page makes this point directly, so a zero in the three attributes does not by itself mean a module does nothing. Machine Modules term page

Module bays and compatibility

Module Bay Expansion Kits can expand a standard machine's module bay up to two times, and each use raises the machine's base value by +100. The term page gives that figure, and the overview advises checking which spaces a kit opens before you buy it. Machine Modules term page

A module is stuck once installed. The Module Extractor removes it and lasts 6 uses, and the Alarm Transmitter Module grants +1 reputation per night. Module reference

Before relying on any of the Probably Stolen modules, check the complete tooltip on your own copy. The overview says the example values are only illustrations of trade-offs. Modules system overview

• For a stat change, identify whether the module affects Efficiency, Quality, or Performance, then account for any stated tradeoff.
• For a recipe or output change, match the module to the named machine or crop and read the full description.
• For the Metal Printer route, pair the Computer Numerical Control Module with the Metal Printer Module for frame and gun-part chips.

Our take on Probably Stolen modules

Probably Stolen modules fall into two useful groups: stat changes and specialized machine functions. Efficiency, Quality, and Performance modules shape machine attributes, while examples such as Metal Printer, Hydroponic, and Junk Processing modules change what a machine can process or produce. Modules system overview

The clearest comparisons are the entries with explicit figures or conditions. Eco, Fineness and Overclock have example percentages, the Metal Printer and Computer Numerical Control pair has a named requirement, the Blast Furnace has a recipe shift, and Neural Core has fixed bonuses. The hydroponic entries are crop-specific, so compare them by crop rather than by stat.

Read the table with two caveats. The base values come only from the collection, and a dash means no source gives that figure. The stat percentages are example values from a video, not fixed numbers for each module name.
