The reference package is installed with motion.job granted, writes a program into its own data directory, and asks the host to run it. What it proves on the machine: a program named with a path and one that is not there are refused by the host, with the machine never asked; the real one is taken by the machine as the package, every line sent and acknowledged; the head moves and the head accelerometer sees it; and the laser latch stays locked with every emission witness at zero. The program commands no laser, so the runner ends the job as one that ended without a discharge. That is what a dark program is, and the test asserts it rather than glossing it: the whole program ran and nothing fired. A job that does fire is cloud.dark-print's and laser.emission-witness's. Three things the first runs taught. A button press needs an "until" - what the press is expected to do - and a dark program never opens an armed window, so there is nothing for a press to arm and the test does not press. The job's lease owner is prefixed "job:". And the job record's emission.samples counts samples taken, not samples that saw light; the witnesses are laser_on_samples, lit_s and thermopile_delta. Proven. The unit suite: 451 tests; install_test: 225 checks. On the bench reference, image 20260922014545 with the cross-built daemons mounted over the image's: exthost.motion-job PASS, with exthost.service, exthost.motion-jog and motion.job PASS beside it. Against the image's own daemons the route is 404.
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.
