ScottW514 a596767a9a forgetest: a press the fixture could not make leaves a notice that comes down at the press
press_now and arm_press hand the arm press to the operator when the
bench actuator refuses it (the box is off) or when the button never
lights for it within the arm wait, and put the notice up for a person.
Those three fallbacks raised the notice without the watch that takes
it down at the press, so the notice stood until the test's next step:
the second-press hazard the watch exists for, because a press during
the job pauses it. Each fallback now calls _clear_when_taken() after
its notice, so the notice comes down the moment the controller takes
the press, as the operator's own path does. 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 where the fixture cannot press: press_now's notice for a
refused press, arm_press's notice for a refused press, and arm_press's
notice for a button that never lit each come down within 2 s of the
press. Three runs OK, the file's 21 tests OK. Negative control on a
scratch copy: the leg against the runner without the three calls fails
at the first press, the notice still standing. 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.
