The pages written on top of the old README inherited its premise: that after flashing you face a gauntlet -- go/no-go checks, a safety net, a mandatory calibration -- before the machine can be trusted with a model. That is not what happens. The factory numbers import themselves on the first boot, a bed mesh loads at the start of every print, and the mod is built to run the files the stock firmware ran. A printer that printed before the flash prints after it. "Your first print" now says so in its first line, and everything under it is optional, ordered by what you would actually reach for: check the offsets are applied, and calibrate only if that disagrees with the machine. Three audiences now, because owner and contributor was not the real split. "For experienced users" sits between them: How a print runs, and How calibration works. Someone who knows Klipper and wants to change what happens around their file has a place to go that is neither a walkthrough nor the build system. What was cut is most of what changed. Pages that were cryptic to the reader they were aimed at -- Printing, Upgrading -- are out of the nav and kept on disk to be rewritten rather than deleted. Within the pages that stayed: Expected output, Probe sampling, What is being measured, the symptom table, the dark-screen diagnosis, TOOL_Z_ADJUST, PLATE_CHECK, the ff-*.cfg inventory, [ff_legacy] and SAVE_CONFIG in a paragraph about factory calibration. Filenames and internals earn their place on an owner page only when the reader has to type them or look at them; the rest moved to the experienced pages or to Internals, where the audience wants them. Calibration became a section rather than a page, because tool offsets are not the only calibration: bed mesh has its own page now, and its own gotcha written down -- BED_MESH_CALIBRATE writes `default`, a print loads `MESH_DATA`, so a mesh probed by hand is a mesh no print will use. Input shaping is described but has no procedure page yet. Several claims came out because they were not true. "Is this for you" listed calibration and input shaping as things the mod gives you; both are the touchscreen's own sequences, recovered and reimplemented, and the notes say so plainly. What the mod actually gives you is that anything speaking Moonraker can drive the machine -- on stock, FlashForge's Klipper does not toolchange at all, it raises a flag and waits for an application that is not watching a Mainsail print, and the print hangs at the first T2. The page now opens by telling most owners not to flash it. Contributors are still deferred. Their pages are regrouped, not rewritten.

Calibration
Your printer is already calibrated when it starts. That is worth saying first, because "flash custom firmware" usually means "and now measure everything from scratch".
The first time the mod boots, it reads the per-unit numbers the stock firmware kept for your machine — where each dock is, where each nozzle sits, where the calibration station is — and saves them into Klipper's own configuration. They are the numbers FlashForge measured for your printer at the factory, and the same ones the stock application was printing with an hour earlier. Nothing is reset, and you do not start from zero.
So on a normal first boot the machine comes up knowing its own geometry, and
TOOL_OFFSET_STATUS shows a nozzle position for every tool rather than
NOT CALIBRATED.
One of them runs without you: a bed mesh is loaded at the start of every print, from the map FlashForge probed at the factory.
The pages in this section are the calibrations you run yourself. What each one actually measures, and how those numbers reach a first layer, is How calibration works.
