laser.verdict-cut held, on the machine, that a stale cooling verdict
mid-cut holds the job dark under the open window with the latch
untouched, and that the clean verdict resumes it lit with no press.
Every part of that is a rule the host now proves:
- dark while held: laser_stream_test rules 24 and 27, check_hold_dark on
every verdict hold's stationary stretch, and check_fire_gaps (ef15c55);
- the hold, the message, the window kept, the latch never written, the
resume lit with no press: rules 24 and 27 (latch sideband [unlock,
lock]), laser_lifecycle_test rule 11, cooling_test.c;
- the physical dwell gap (a kernel-run gap inside the unlocked window,
the button latch clear, HV_ENABLE back lit): laser.emission-witness,
unchanged.
- Its own lines go, decorator through body, and nothing else:
DISARMED_MSG, the module constant only its check read, stays with the
blank lines around it, so laser.py's shared text is unchanged.
- test_laser_verdict.py goes: every case loaded dark_span out of
verdict_cut's body.
Proof: the fingerprint parts of laser.py before and after: the shared
text unchanged, the other five tests' own text unchanged. The coverage
lint reports 0 uncovered paths and 0 host-tested row problems over 109
tests (its one failure is setup.check-lens's src/lensfind.* entry, which
the forgectrl pin bump clears); the gate self-check refuses an empty
artifact cleanly; pyflakes adds no finding; the forgetest host suite
passes under Linux (539 tests).
Acceptance: the catalog hash moves; no remaining test's fingerprint
moves.
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.
