Two harness faults found on the bench reference in the campaign on image
20260923084705.
setup.gate-blocks-controllers probed the Grbl port once, at the moment
GET /mode first read the controller running. The supervisor reports
running from the fork and the controller binds TCP 23 a few tens of
milliseconds later, so the probe failed whenever the 0.25 s poll landed
inside that window ("the Grbl port is closed with the controller
running"). Timed on the board with the controller restarted through
forgectrl: /mode read running at 0.066 s, the port accepted at 0.087 s.
The test now waits up to 10 s for the port (50 ms polls) and records
how long it took (port_open_after_s). PASS on the bench (0.001 s).
first_run() replayed the system accounts (forgefirm-users reload) and
removed the temporary home only after its block succeeded. When the
block failed, the records came back but /etc/passwd kept the temporary
account in place of the operator's, and image.health failed after it
(the record's account missing from /etc/passwd). The replay and
the home removal now run in a finally. Proof on the bench: the failing
case run on purpose (setup.first-run-flow against the image's own
forgectrl, which refuses a home by hand at the cloud step) leaves the
operator's account the one account from uid 1000 up and no temporary
home; the same failure before the fix left the temporary account in
/etc/passwd and its home in /data/forgefirm/home.
forgetest's unit tests: 452 OK. setup.first-run-flow and
setup.gate-blocks-controllers PASS on the bench with this file mounted.
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.
