The file held three unrelated things behind one name: gates deciding which services boot, switches for the splash / the startup wait / the first-boot import, and tunables for the camera and the nice values. Every one of them defaulted to on, and what each offered was a half-installed printer -- a state nobody chose on purpose and everything downstream carried a second answer for. firmwareExe no longer expands the ok-all bundle and filters it, it asks for the bundle: BOOT_SET=ok-all. A printer that should not run a component does not have it -- `opkg remove`, or a stock FlashForge package. The settings worth keeping are each stated once now, in the service that uses them: the camera's resolution in its run script, nice 10 there and nice 5 in moonraker's (the values every install was getting from the template, not the 0 the inline fallback said). ff-startup's `up` stops passing --timeout and --klipper-tries at all, because 240 and 6 are already ff-startup.py's own defaults and two statements of a default can disagree. Nothing sources the file, so nothing reads it, so it must not survive an upgrade looking editable. run-append.sh stops preserving it and removes it unconditionally beside init.d and anvil-service.sh -- unconditionally because the pre-manifest sweep removes seven DIRECTORIES and would leave this file sitting at the top of $MODDIR. The two upgrade tests that asserted the edit survived now assert the file does not. seed/ leaves anvil-core entirely, which takes with it the recipe's one exception to "every sibling directory is shipped", the seed mount in the replica plumbing, and its exemption in the .ipk allowlist.

Reforge
Custom firmware for the FlashForge Creator 5 and Creator 5 Pro.
It installs the way a normal FlashForge update does: copy one file to a USB stick, plug it in, power the printer on. No jailbreak, no soldering, no opening the case, no ssh needed to get started — the printer's own updater does the work.
Packages are published on the Releases page — two files per release, one per model, marked pre-release while the mod is young. Help and support: the Discord.
Unofficial and unaffiliated with FlashForge. It voids your warranty and you are responsible for your machine. See Status for what has actually been tried on hardware before you flash anything.
Status
It runs on a real printer — a Creator 5 Pro, flashed and printing:
A checked box happened on that machine; an empty one has not, yet.
For everyone:
- Install and migration from stock firmware — the printer's own updater does it; your unit's factory calibration imports itself on the first boot
- Printing — gcode straight from the slicer, nothing edited
- Toolchanges — a current Klipper with real toolchanger support, in place of the 0.12-era tree FlashForge ships
- Nozzle-offset calibration
- Mainsail at
http://<printer-ip>/, with a current Moonraker behind it — anything that speaks the Klipper API works - Camera — mjpg-streamer, already on the printer; the mod just starts it
- Wifi
- HelixScreen on the printer's own screen
- Chamber heater
- Creator 5 (non-Pro) — its package builds and passes the same replica test suite, but has not touched hardware
- Going back to stock — proven on the printer replica, not yet needed on the machine. The stock package restores everything it carries; Moonraker is not in it, so the mod's build stays and keeps working — see Support
For the tinkerer:
- ssh as root — a random password is chosen on the first install
and written to
anvil-password.txton your stick; updates keep it (make passwdbakes in your own)
What you give up
FlashForge's application is one binary, and replacing it takes everything
that lived inside it: the network API on :8898, and with it FlashPrint,
Orca's FlashForge profile and the mobile app. Moonraker's API takes over.
Flashing the stock package brings them back.
If your prints already come out the way you want and you like the printer's own screen, this mod is not for you. It trades FlashForge's polish for Klipper's reach, and it expects you to be comfortable with a Klipper config and an ssh session when something breaks — Is this for you is the honest version of that question.
Get it
Creator 5 and Creator 5 Pro are not interchangeable. The printer refuses a package built for the other model — the most common reason a flash "does nothing". Yours is in Settings → About.
| Your printer | The file on the Releases page |
|---|---|
| Creator 5 | Creator5-anvil-<date>.tgz |
| Creator 5 Pro | Creator5Pro-anvil-<date>.tgz |
Download the stock FlashForge package for your model before you begin. It is the undo button: flashing it back puts the printer as it was.

Built on the work of others: ghzserg/FF publishes the stock packages and factory image everything here starts from; Mainsail, Moonraker and HelixScreen are shipped as released; the toolchanger status API follows viesturz/klipper-toolchanger so tool-aware UIs work unchanged.
