The "No undefined names" step runs under bash -e with no pipefail, and
-e does not reach the condition of an `if`. The former body pipes the
pyflakes run into grep, so the step's status is grep's alone: with
pyflakes absent ("No module named pyflakes" on stderr, exit 1) or
crashing, grep sees no match, the `if` is false, and the step passes
with nothing checked. Its `pip install pyflakes` also names no
interpreter.
The step now installs with `python -m pip`, into the interpreter it
runs; runs `pyflakes --version`, which fails the step under -e when
the module is missing; captures the pyflakes run, stderr included, in
a file (its own exit status is 1 for any message, unused imports
included, so it cannot be the gate); and fails on "undefined name" or
on "Traceback", a crash. The grep is pinned to pyflakes' message text;
no pyflakes version is pinned.
Proof: the step body, read from this workflow, run under bash -e over
the forgetest tree on Ubuntu 24.04 with python 3.12, against the
former body as the control. pyflakes missing: the former body exits 0,
this one exits 1. pyflakes 4.0.3 present, the tree as committed: both
exit 0 (22 unused imports and 2 unused locals, no undefined name). An
undefined name planted in a scratch copy: both exit 1. A pyflakes that
raises (a shim, scratch only): the former body exits 0, this one exits
1. In CI the step's log shows the pyflakes version before the check.
Acceptance: none; CI only. .github/ is outside meta-forgefirm and
every covers map.
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.
