Circuit connector placement helper

Circuit Connector Placement Helper on Your Factorio Server

This helper mod by Quezler is aimed at modders and prototype developers: it lets you place a circuit connector directly in-game and then export its position to the data stage. Instead of calculating coordinates by hand, you position it visually while playing and carry the result straight into your code.

Setup on your rented server takes only a minute: drop the zip into the mods/ folder and enable it via mod-list.json. Since mods sync automatically to every client on join, fellow developers on your team can jump in and experiment on the same server without any manual install steps.

Tip: Great for small modding teams sharing one server as a testbed for new prototype work.

Plan the rollout and operation

The Placement Helper belongs on a development or staging server, not permanently in an ordinary factory. Create a reproducible test object, export the coordinates, and transfer only the result into the actual mod code. Validate the export with rotated variants and different collision boxes. Remove the tool before production launch so players do not see development functions and the live mod list stays clear.

For rollout, copy the save, mod-list.json, mod-settings.dat, and current mods directory. Enable the new zip on a server copy first and let Factorio validate dependencies and version ranges during boot. Connect at least two clients, use the core feature, save under a new name, and load that save again. Watch the server log, UPS, and synchronization in a realistic factory rather than only on an empty map. For updates, record the game, mod, and dependency versions together and change one package per test run. Content or recipe mods can leave saved entities and production chains behind, so do not remove them directly from the live world. On a copy, replace recipes, filters, and buildings before deleting the file. The original save then remains a reliable rollback. Also document the tested mod order so teammates and later maintenance windows always begin from the same reproducible combination.
