The reference package takes the hold capability (its service ends at once when the test leaves a file in its data directory: a package that cannot speak for itself). The install is refused without the operator's grant; a granted hold is advisory until `forgeext hold <id> required` names the package under required-holds. With extensions on, the required hold stands in the host's words until the service has run healthy, then the host keeps its file fresh and clear and GET /cool/status reads OK. The test then makes the service end at every start: verdict EXT, fire_ok false, hold true, the reason naming the package, and never clear in 24 looks over the crash loop. Safe mode ends it within four seconds and leaving safe mode brings it back; marked advisory it is dropped; marked required again and the host suspended, the reason becomes that the host is not answering, and resumed it is the package's again; ext_enabled=0 ends it. The verdict is read at idle: nothing moves and nothing fires. Everything is put back as exthost.service puts it back, the required holds are empty, and the verdict is OK at the end. Proven. The unit suite: 451 tests, 0 undefined names. On the bench reference, image 20260921121235 with the cross-built forgectrl and extension host mounted over the image's: exthost.hold-pause-tier PASS (held 1.0 s after the service was killed; safe mode released it in 0.8 s, extensions off in 0.8 s); against the image's own forgectrl, whose engine knows no holds, it FAILS with the verdict OK, as it should. Acceptance. The test is new: auto, takeover. It covers forgeext's src/holdkeep.*, src/run.*, src/install.*, src/state.*, src/main.c, and forgectrl's src/holds.* and src/cool.*, and requires exthost.service.
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.
