Each test below leaves for the host cases that now hold it, every one
run and passing before this commit:
- cooling.fans-quiet-after-motion, cooling.gate-off (its engine half),
cooling.floor-and-warm-up, cooling.tec-drive, cooling.fire-watch-tiers,
cooling.crash-watch-plumbing, cooling.critical-tier and
cooling.fan-gate-trips: forgectrl's cool_flow_test and cool_gate_test
(forgectrl 8e9cc0a). The jog and M8/M9 report stays in grblHAL's
cooling_test.c and cool_report_test.py; real heater climb, a lit tube,
tach spin-down and fans meeting their floors stay with
cooling.flow-verify, cooling.flow-under-load, cooling.fail-tier-stop,
cooling.aa-offset-calibrate and setup.check-airflow.
- motion.gate-waits-for-lid: super_test D2 (forgectrl 8e9cc0a). The
physical lid read stays with setup.check-switches.
- motion.lid-cancel-home: laser_lifecycle_test's hold-lid-cancel (forgefirm
107676b). check_kernel_returned stays in laser.pause-resume-lid-cancel's
live lid phase.
- homing.manual: manual_home_test.py cases 1 and 7, and status_test's
anchor readback (forgectrl 8e9cc0a).
- laser.recorder-dark: curverec_test (forgectrl 8e9cc0a). The dark arm
wait stays test_button_wait_arms.
cooling.gate-off's board half moves into image.health: /status
temps.chassis_c from 5 through 80, temps.soc_c from 10 through 100,
temps.supply_raw an integer from 0 through 1023, and temps.soc_throttle
0. image.health's covers gain src/status.*, which serves them. The next
campaign reruns image.health (it is always run).
Stays: motion.cancel-abort (its host case fails on the abort's cnc/stop:
the null-sink controller writes cnc/stop only with a device open),
exthost.service (its init-script case has not passed on unmodified code
here), exthost.armed-freeze (its armed-capture decision has no host
proof), exthost.motion-jog (the package's jog through the host credential
has no host proof), exthost.motion-job (its POST /job reader is step 4's
jobpost_test.c).
Requires re-pointed off the tests that left: setup.check-airflow and
setup.check-intakes no longer require cooling.fan-gate-trips,
laser.pause-resume-lid-cancel no longer requires motion.lid-cancel-home,
cooling.fail-tier-stop no longer requires cooling.crash-watch-plumbing,
and exthost.armed-freeze no longer requires cooling.floor-and-warm-up.
cooling.py's docstring now describes the four cooling tests that stay.
The helpers only the departed tests used go with them, and laser.py
imports only the motion helpers it still calls.
Proof: the coverage lint on the tree manifest reports 0 uncovered paths
and 0 host-tested row problems across 66 tests; its one failure is
setup.check-lens's src/lensfind.* entry, which clears with the forgectrl
pin. No HOST_TESTED row was needed. The catalog validates; pyflakes
reports only the two unused locals that were there before
(cooling.fail-tier-stop's t0, update.py's plain);
test_cooling_order, test_cooling_suite, test_image, test_laser_dwell,
test_camera_home_return, test_setup_dark, test_setup_burns,
test_kernel_suite and test_cloud_suite pass.
Acceptance cost: the catalog goes from 78 tests to 66. Implementation
hashes move for cooling.aa-offset-calibrate, cooling.flow-verify,
cooling.flow-under-load and cooling.fail-tier-stop (cooling.py's shared
text); motion.pacing, motion.jog-roundtrip, motion.microstep-modes,
motion.liveness-probe, motion.cancel-abort, motion.deadman,
motion.step-timing-under-load, motion.release, motion.job,
laser.armed-kill, laser.emission-witness, laser.pause-resume-lid-cancel
and setup.check-envelope (motion.py's and laser.py's shared text, and the
modules that import motion.py); image.health, setup.check-airflow,
setup.check-intakes and exthost.armed-freeze (their own text).
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/).
Start here
https://docs.forgefirm.org/ is the documentation, and the source of truth for every fact about the machine and the firmware.

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.
