The catalog is 43. Each test leaves for a host proof that its component's CI runs at the pins: - setup.account-login: the login rules are host_routes.sh's (forgectrl 6c2bb38); the render is test_image.py's new AccountRenderTests, which runs the layer's forgefirm-users.init with reload in a private mount namespace as root (a fresh /run, the scratch account files over /etc, the scratch data directory, root's, over /data): the data directory found 0700 is 0711 after the render, and as the account's own uid the home is entered and written while listing the data directory and reading the users record are EACCES. A control without the script's chmod go+x fails it (700 != 711). forgectrl.auth's cover widens to src/ui/login.*, since login.html had no other cover. - motion.cancel-abort: laser_lifecycle_test.py's new rule 17 on the null-sink controller: 0x85 stops a jog short of its target, Idle; ^X mid-move lands in Alarm with the position kept and no return to the job start; $X recovers to Idle and the next jog ships steps (counted in GFSINK_DUMP). It passes on the driver at its pin, badc832. motion.deadman requires motion.pacing in its place. - forgectrl.settings-bounds: host_routes.sh refuses the out-of-range and over-length values with the settings file byte for byte the same, and the lid lamp under GF_SYSFS_ROOT follows lid_lamp_idle (forgectrl 6c2bb38). - exthost.service: forgeext's host tests at the pinned bb75b23 - sandbox_test (the confinement from inside, the pulse device, the settings file and the setup record refused), run_test.py (the API, safe mode, the master switch, and the killed host under the init script's own wrapper), install_test.py and sdk_test.py. exthost.armed-freeze requires exthost.platform in its place. HOST_TESTED rows for each path the lint named once exthost.service left: forgectrl src/logs.* to logs_test.c and docs/advisories/extensions.md to host_setup.sh; forgeext src/api.*, caps.*, evfeed.*, holdkeep.*, httpreq.*, manifest.*, quota.*, sandbox.*, settings.*, state.* to their unit tests, netrules.* to netrules_test.py, call.* to sdk_test.py, install.*, pkg.* and index.* to install_test.py, and main.c, fflog.* and CMakeLists.txt to run_test.py. test_manifest's behavioral-path case is unaffected. The rootfs lint takes image.health's file checks (rules init-order, logging, watchdog, read-only, dhcpv6, and on a release image factory), each proved in RootfsLintTests by a drift that fails it. image.health keeps the live half: the rendered issue and motd against the running manifest, one host and no pool process, watchdog0, no userspace watchdog running, the mounts, the dev image's factory slots read-only, no DHCPv6 client running, the DHCP client's -b and parent, ifup, the getty, and IPv6. release.sh drops its PermitRootLogin and PermitEmptyPasswords greps, its ROOTFS_READ_ONLY check and its /factory fstab check, which the lint holds; it keeps the empty root shadow field, / mounted ro, and the three HostKey lines under /data. setup.py registers no test now: its helpers the deleted tests alone called go (tls_base, tcp_open, mode, press_status, wiz_summary, wait_settled, the login constants), and test_setup_suite.py keeps the cases of what remains. Fingerprints: image.health's moves (its text), every test in exthost.py, forgectrl.py and motion.py moves with its module text, and the layer content hash moves with rootfs-lint.sh: the next image inherits no campaign. Proof: the coverage lint over the tree manifest from the pins finds 0 uncovered paths and 0 host-tested row problems (43 tests); pyflakes on the touched files is clean; forgetest's unit suite under Linux passes (334), test_image.py's 28 among them. The lint passes image 20261015142442's release tree as release and its dev tree as dev, and refuses the dev tree as release (sshd, factory). laser_lifecycle_test.py passes whole on the null-sink build of badc832.
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.
