ScottW514 0ceb4abc4a forgetest: cooling.fail-tier-stop waits for the crash fault to end with its session
The test raised a crash fault and handed the machine back with it still
standing. The engine trips the crash tier on one 1 Hz tick and ends the run
session on its next tick, which is when the fault and its hold clear ("head
crash fault cleared with the run session"). The supervisor has the new
controller up inside that second, and the test returned as soon as it saw
the new pid and the two log lines, so the runner's hand-back check could
read /cool/status before the clearing tick: phase run, hold true. A hold is
the run's doing by the baseline's rule, so the check recorded a leftover
and failed the test, though the wait that followed ended on its own.

Seen on the bench reference in campaign c-20260919202934-3d3a, the only
failure among 65 results: the trip at 20:54:44.871, the new controller at
20:54:45.094, the test's PASS line at 20:54:45, the session end at
20:54:45.863, and "cool=run/armed=False/hold=True ... -> waited" from the
hand-back check. The engine opened no session after that one; the 16 s the
check waited were the smoke phase that follows an armed session.

The test now asserts what the engine documents: after the restart checks it
waits up to 10 s for the verdict to leave CRASH, records how long that took
(fault_cleared_s) with the phase, verdict, hold and armed flags it found,
and fails when the fault does not end with the session. The machine is then
handed back in the engine's own post-job phase, which the baseline already
treats as the engine's work and not a leftover.

Proven: the cooling, artifact, campaign and queue host tests pass and the
catalog loads with the new source. No component source changed, so no pin
moves; the test's own source hash does, so its result comes from this
revision.

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.
