An extension package is software the image does not carry, and a result taken beside one is not a result about the image. Two places hold the line. The baseline (_ext_side, in every pre and post pass): a package under the tests' own prefix (org.forgetest.) and an owner key named forgetest-*.pub are what a test made and left behind; they are removed (forgeext remove, the key's file), recorded as restored, and the host stops the service on its next turn. A process that still runs under a pool account after that belongs to the operator's own packages: it is recorded as unrestorable and never touched. An installed package that does not run is nobody's leftover. hw.pool_pids() reads each process's Uid line; hw.ext_packages() lists the package directory. image.health (5b): the extension host is one process (/usr/bin/forgeext run), its start link sorts after forgectrl's and its kill link before it, no package is installed, and nothing runs under a pool account. Proven. test_baseline.py, ExtensionFreeTests, over a stand-in forgeext and a fake package tree: an installed package that does not run leaves nothing; a test's package and key are removed and the operator's package and key stay; a removal that fails says so in the host's own words; running extensions are reported and left alone. The unit suite passes (451 tests, 0 undefined names). The link order image.health asks for is the one the built root filesystems of image 20260921014201 have: S90forgectrl before S91forgeext, K09forgeext before K90forgectrl. Acceptance. image.health gains forgeext's init/** in its covers map; it runs first in every campaign and is the on-image proof of 5b. The baseline is harness, outside the suite and outside 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.
