forgeext is the extension host, a component of its own: recipe recipes-forgefirm/forgeext (cmake, pkgconfig, forgefirm-manifest, so it is a manifest component with its own pin file). It links jansson, libarchive, and libsodium, and runs with fwup, the keyring, and forgefirm-sandbox. libarchive and jansson are on the image already; libsodium comes with it. The pin is all zeros because the repository has no pushed commit to name: the recipe builds from a working tree through externalsrc, and a build from pins cannot fetch it until the first push sets the pin. It is not in the image's install list. forgefirm-keys installs a third trust anchor, /etc/forgefirm/keys/ext/forgefirm-ext.pub: the OpenGlow extension-signing public key, the official tier of extension packages. It is a different key from the release key on purpose: it signs more often, and its loss must not sign firmware. forgeext refuses an extension archive whose only valid signature is the release key's or a factory key's. Proven. The recipe cross-builds forgeext from the working tree, and that binary ran the verify-and-install cases on the bench reference (image 20260920211625, from /tmp, with the board's own fwup 1.16.0 and the image's keyring) with the results of the host test. forgefirm-keys builds and packages the key 0644 under ext/ (0755), byte-identical to the file here; it is 32 key bytes and is not the release key. Acceptance. No catalog test reads either yet: forgeext's tests are the exthost suite that comes with its daemon, and the key is layer content, in the platform identity of every fingerprint.
OpenGlow / ForgeFIRM firmware for Glowforge
BETA
ForgeFIRM is in beta. Every release below 0.1.0 is a beta release. Expect problems, and expect frequent updates. Upgrade whenever a newer release is available, and report what you find on the community forum.
Open firmware for Glowforge brand CNC lasers. ForgeFIRM replaces the cloud-dependent factory software on the stock control board, with no hardware modification, and gives the machine a local controller, a local web control panel, and a standard Grbl interface. The factory cloud experience stays available as an option.
This repository is the base of the build and of the release: the
meta-forgefirm Yocto layer, the kas configuration, the image recipes, the
install and release scripts, the acceptance tool (forgetest/), the bench
tools (scripts/bench/), the bench actuator firmware (fixture/), and the
release artifacts (releases/).

Build
kas build kas/forgefirm-glowforge.yml
Build covers the host setup, the two images, the source variant and the debug kernel. Release flow covers the pins, the push order and the signing pipeline.
Test
cd forgetest && python3 -m unittest discover -s tests -v
The acceptance catalog that gates a release, and the bench tools, are on Acceptance and The bench.
Contributing
AGENTS.md carries the rules for this repository and for the project: safety ordering, proof before done, the push order, and the writing rules. They apply to human contributors too, and Contribute is the same set on the site.
What this costs
Nothing. ForgeFIRM is free in both senses, under MIT and GPL licenses. There is no paid tier, no license key, no subscription and no Pro edition. If someone offers to sell it to you, the licenses allow it, but what you take home is their build rather than this one: get it from the source.
Safety
These machines contain a CO2 laser: it burns, blinds, and starts fires. Never defeat the lid switches or the interlock. Never leave a running job unattended. Keep a fire extinguisher within reach. Read Safety before you cut your first job, and Regulatory and legal before you install.
This is experimental software. Use of it could seriously maim or kill you or others, and it may void your warranty. Use it at your own risk.
