A new catalog test for the one subscription the extension host holds and the poll a package reads it with. The reference service learns from GET /v0/self whether it was granted events and polls POST /v0/events only then, so every other test keeps the half-second heartbeat those tests watch; what it polled and what it saw go in its data directory. What it proves on the machine: the host holds the stream while one package wants it and lets it go when none does; a poll that names its place and has nothing to be told comes back at its own deadline and not before, while the first poll, which only asks where the present is, comes back at once; the lid opened and closed on the fixture reaches the package as lid events, in order and numbered, which also proves a waiting poll is woken rather than left to time out; and with the three ordinary streams taken the host's subscription is still there while a LAN client that asks for the host's slot by name is refused, because only a loopback peer may claim it. The three ordinary streams each bind a source address of their own. The cap counts peer addresses, and the kernel sends every loopback connection from 127.0.0.1 whatever address it was aimed at, so three streams without that would replace each other and leave two slots free. The first run of this test said a LAN client had been admitted; it had been, correctly, to a slot the test had failed to fill. Proven. The unit suite: 451 tests, and the coverage lint passes. On the bench reference, image 20260921171224 with the cross-built forgectrl and extension host mounted over the image's: exthost.events PASS, and beside it exthost.service, exthost.armed-freeze, exthost.hold-pause-tier and events.stream PASS. Against the image's own daemons exthost.events FAILS at its first new check, as it should. The bench was left as found, GRBL mode, no mounts. Acceptance. exthost.events covers forgeext's src/evfeed.*, src/api.* and src/run.*, and forgectrl's src/events.* and src/main.c.
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.
