Frequently Asked Questions
How does FPSCompress run factories without keeping chunks loaded?
A PreFab Machine force-loads your Compact Machines room during a short SIMULATING calibration pass to measure exact input and output rates per tick, then unloads the room in CACHED mode and transfers items using fractional math.
Why did my PreFab Machine switch into the HALTED state?
A PreFab Machine enters HALTED automatically when an Overworld input container runs out of supplies, an output container fills up completely, or a linked Importer or Exporter inside the room is broken.
How do you recalibrate a PreFab Machine after changing machines inside?
Craft a Simulation Wrench from four Copper Ingots and right-click the PreFab Machine to restart the SIMULATING measurement phase.
How do you label Importers so they do not show UUIDs in the menu?
Hold a sample item such as Coal or Iron Ore and right-click the Importer inside the Compact Machines room to name its frequency for the PreFab dropdown list.
Which resource filter should you select on PreFab faces?
Select the ITEMS filter when setting up PULL and PUSH faces, as item stack transport is the active channel while ALL, FLUIDS, and ENERGY are unfinished placeholders.
