forgectrl c274f19 adds cool_intake_fans: at 1, a machine built with one
intake fan, the second intake is published not fitted and never judged,
and the setup's airflow check writes the count it finds.
cooling.intake-one-fan, in a suite module of its own, proves both halves
on a machine with two intake fans with the setting alone. With
cool_intake_fans 1 and an 8 s grace, a session at the cut fan profile
must publish intake_2 as not fitted with no floor while it reads a real
speed, run OK, and judge intake_1 ok at the intake floor; with the intake
floor at its legal maximum it must trip AIRFLOW (hold, fire blocked) with
intake_1 TRIPPED and intake_2 still not fitted, and the fault must end
with the session; restored, every fan reads ok at its floor. It starts
only from a machine with both intakes judged, requires
cooling.fan-gate-trips, and puts the count, the intake floor and the
grace back as found on every exit path.
setup.check-airflow now reads the count from the result: 2 needs all
four fans at least 1000 rpm, 1 needs intake 2 reported {"fitted": false}
and the other three ok; either way the setting must read what the check
found, and the count is put back with the five floors.
Fingerprints: the new test has a module of its own, so no cooling test
moves; the setup.check-airflow edit is inside its function. Diffed across
the change: 127 -> 128 tests, one added, setup.check-airflow the only
one moved.
Proof: the touched host tests pass (test_cooling_intake_suite 4,
test_setup_dark 10, test_cooling_suite 25) and pyflakes is clean.
test_cooling_intake_suite replays the test against a scripted engine,
and two broken engines fail it with the settings put back: one that
ignores the setting, and one that takes intake 1 out with intake 2.
test_setup_dark's new AirflowCheckTests take a two-fan and a one-fan
result, and fail a count the setting does not match and a result with
no count. On the bench reference, image 20260928194539 (dev) with these
files and forgectrl c274f19 bind-mounted, cooling.fan-gate-trips,
cooling.intake-one-fan and setup.check-airflow pass with a clean
baseline before and after each (forgectrl's commit has the readings).
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.
