Common Config Reference

The older public page listed only a subset of mm-common.toml. The provided 1.20.1 source defines these options:

# Enables async structure validation to improve TPS. Disable in case of issues.
asyncValidation = true

# How often controller will check structure. 1 means every tick, 20 means every second.
structureValidationRate = 10

# Enables the Debug Tool Item's functionality.
debugTool = true

# Splits JEI recipe viewer categories by the structure they belong to.
splitRecipesJei = true

# Default value of autoPush when a compatible port omits autoPush.
portsAutoExtractByDefault = false

# Default value of parallelProcessing when not set elsewhere.
parallelProcessingDefault = false

# Global max parallel recipes per controller.
maxParallelRecipes = 5

# Show the max parallel-processing line in JEI structure view.
showJeiMaxParallel = true

[preview_features]
# Enables the experimental blueprint screen.
previewBlueprintScreen = false

Practical recommendations

• asyncValidation is defined in the common config, but in the provided source snapshot the directly visible controller timing check uses structureValidationRate. Treat asyncValidation as experimental unless you verify behavior in your build.
• Increase structureValidationRate if you have many controllers and want less frequent structure checks.
• Disable debugTool on public servers if players should not generate debug dumps.
• Use portsAutoExtractByDefault = false and enable autoPush only on ports that need it.
• Keep global maxParallelRecipes modest. The common config value is ranged 1..100 and defaults to 5. Controller/structure builder values are separate and may use -1 as an unspecified/fallback value.

maxParallelRecipes range

Global common config maxParallelRecipes is ranged 1..100 and defaults to 5. Do not use -1 in mm-common.toml; -1 is only used by individual controller/structure builder/config fields to mean unspecified/fallback.
