- The presence press at the Ready gate polled forgectrl's /status over HTTPS every 0.25 s plus the request's own time, so a short press fell between two reads and the operator held the button for seconds. It is read as an edge from the switches' input events (hw.ButtonEdges, no grab), opened before the notice goes up: a press of any length counts. Events read and not yet looked at are kept, so a short press whose release arrives in the same read gives the release to the next wait. With no switches device (the host harnesses) the status is polled at 50 ms. - An operator's arm notice (arm_press, press_now) stood until the test's next step, over a press already taken. A watcher takes it down the moment the controller puts the button out at the press; a notice put up meanwhile is left alone. Proof: host tests: a press and release written back to back on a FIFO standing in for the switches' device pass the Ready gate in well under a second with the status never showing the button down (the first version dropped the release with the press and waited 10 s: the test caught it); the arm notice stays while the button is dark or lit and goes down when it goes out, and a notice put up meanwhile stays. The fixture (35), setup (87), manifest (26) and operator (22) host tests pass. Acceptance: these are the harness's own paths; every live and operator test with a press runs through them.
OpenGlow / ForgeFIRM firmware for Glowforge
BETA
ForgeFIRM is in beta. Every release below 0.1.0 is a beta release. It's stable, but you may still hit the occasional bug, 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.
