A new catalog test, in a module of its own (suite/extcall.py) so that no other test's fingerprint moves. It installs the reference package's id and key with a page and a service of its own, whose service reports what it was handed and answers its page's calls on the listening end the host gave it. It holds: FFX_CALL_FD=4 with descriptor 4 a listening socket and 3 and 5 closed; the socket root's 0600 in root's 0700 directory; POST /ext/call relaying a POST and a GET, the service's own refusal passed through as its status and words, and a service asking the API while it answers; five calls out of form refused, 400 by the relay or 409 in the host's words; forgeext call answering alike; and a disabled package refused in words, its service stopped and its socket's name gone, then answering again once enabled. The package, the key, the setting, and the setup record are put back as found, and no socket name is left. covers: forgeext src/call.*, src/run.*, src/sandbox.*, src/main.c; forgectrl src/extpkg.*, src/main.c. Proof: on the bench reference (image 20260922225653, with forgeext 5c13f1c and forgectrl 2cf6b12 cross-built and bind-mounted, and this suite bind-mounted over the installed one), exthost.page-call PASS in 16 s, and exthost.service, exthost.ui-delivery, and exthost.package-routes PASS in the same campaign. forgetest's unit tests: 451, one failure in test_cloud_suite, whose replayed prints flake on their timing alone as well (1 of 3 runs of that module by itself, in a different test each time) and touch nothing of this change.
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.
