Fixture._press said that a check that must reach the machine while the button is down asks for the longest press the box can make, and the unit test's comment repeated the invitation. That contradicts the design: no press is ever held, every reader of the button catches the default press (an edge, or a poll of 100 ms or less), and the box clamps any request into 20 to 500 ms. The docstring now says what `ms` is (the box's own 200 ms when it is not said, clamped by the box) and that no check needs a longer press. The `ms` plumbing stays: it mirrors the box's API field, and the box clamps regardless. The test's pass-through assertion stays as the client's contract that a request reaches the box as asked; the clamp is the box's, held by the fixture firmware's policy test. Proof: forgetest-ci "Unit tests" (`python -B -m unittest discover -s tests -v` in forgetest), on Ubuntu 24.04 with python 3.12: the ClientTests of test_fixture.py, 6 tests, OK. A grep for "longest press" and "while the button is down" over fixture.py and test_fixture.py prints nothing. Text only, so no negative control applies. pyflakes reports no undefined name. Acceptance: none. fixture.py is a non-suite module outside the shared judges, and tests/ are in no fingerprint; no press length or path changes.
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.
