_clear_when_taken takes the operator's arm notice down the moment the
controller takes the press (the button lights for the arm wait and
goes out at the press). Its watch thread polled the button LEDs every
50 ms with the arm's timeouts as its only exits: 30 minutes for the
button to light, 90 minutes in all. Nothing in it read the run's end,
the abort event, or whether the notice it guarded still stood, so a
test that ended before the press (a FAIL on the way to the arm) left a
thread reading up to six sysfs files twenty times a second behind it.
The watch now lives only as long as the notice it guards and the run:
a notice cleared or replaced, a run that finished, or an abort ends
it. `standing()` reads both under the run's lock on every poll, and
the poll waits on the run's abort event instead of sleeping, so an
abort ends the wait at once. The cadence stays 50 ms: the notice still
drops within 50 ms of the press. The watch commands nothing; no press,
judge, or energy path changes.
Proof: forgetest-ci "Unit tests" (`python -B -m unittest discover -s
tests -v` in forgetest), on Ubuntu 24.04 with python 3.12:
test_fixture.py's test_the_arm_notice_comes_down_when_the_press_is_taken
gains the leg that a run finished before the press ends the watch
within 2 s and leaves the finished run's notice as it was; the file's
21 tests pass; test_setup_burns.py, whose burns reach the watch
through press_now, passes its 19 tests and leaves no
forgetest-arm-notice thread behind (10 before this change); and
test_server.py, test_operator.py and test_queue.py pass. Negative control on a scratch
copy: the new leg against the unchanged runner fails with the
forgetest-arm-notice thread still alive after the run finished.
pyflakes reports no undefined name.
Acceptance: every catalog test's fingerprint moves: runner.py is a
shared judge, in every implementation hash (43 of 43 move). Against
the campaign this series already needs, that adds no run: 850498f
moved all 43 once. tests/ are in none.
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.
