ScottW514 d40ebb090e cool_report_test: the homing runner is handed the report secret
The runner case asserted that the homing runner the controller starts
does not inherit GF_REPORT_SECRET. The runner is the reporter while a
gfcloud $H holds the machine (the controller sends no report then), so
the assertion described the defect: every camera home ran with nobody
reporting, and the cooling engine's hung-controller dead-man stopped the
session's first motion.

The case now requires the runner to be handed exactly the controller's
secret, and two new cases require that it be handed none when the
controller was started with no secret (runner-none) or with one that is
not 32 hex digits (runner-malformed). The harness's descriptions in
scripts/bench/README.md and in the bench page's catalog say so.

Proof: all 11 cases pass on the driver that hands the secret over
(grblHAL-glowforge, "gfhome: the homing runner is handed the report
secret"); the driver before it fails the runner case: "the homing
runner was handed [], not '0123456789abcdef0123456789abcdef'".

Acceptance: a host harness in the driver's CI; no catalog test runs it.
forgetest/forgetest/bench.py changes one description string, which no
test judges.

OpenGlow / ForgeFIRM firmware for Glowforge

BETA

ForgeFIRM is in beta. Every release below 0.1.0 is a beta release. Expect problems, 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.
