The catalog is for what needs the machine or an operator. Each test below asserted software rules that a host test in CI already proves, read assertion by assertion next to that host test before it left; the record of that reading is kept with the audit. Safety rules (each approved for deletion by the owner on that reading): - laser.disarm-in-hold: laser_lifecycle_test test_resume_after_grace. - laser.arm-wait-lid: laser_arm_test E-G, laser_lifecycle_test test_lid_open_in_wait. - laser.port-dark: ctlport_test test_port_dark (port jogs, a long jog and its cancel, four injected words, the panel ops: no FIRE tick under an open window with M3 modal). - motion.respawn-gate: super_test A and D. - motion.interlock-cancel-home: the lifecycle loop cases, laser_arm_test G. - motion.lid-policy-hold: laser_lifecycle_test test_lid_policy_hold. - cloud.lid-during-button-wait, cloud.dark-print, cloud.verdict-refuse, cloud.paused-lid-cancel: test_machine_lid_button.py. - cooling.fan-duty-readback: cool_fanwrite_test. - cooling.intake-one-fan: cool_intake_test A-E. - exthost.hold-pause-tier: holdkeep_test, run_test.py, cool_flow_test P, holds_test. Other rules: - homing.cloud-offsets: manual_home_test [own-offsets], test_gfhome_motion; the real session stays in cloud.mode-switch. - exthost.core-range: version_test, install_test. - exthost.operator-destinations: run_test.py, netrules_test, install_test, extpkg_test. - exthost.lifecycle: run_test.py's ext.shutdown read before the stop. - exthost.mcode: the null-sink mcode_test, forgectrl mcode_test, sdk_test, install_test. - motion.soft-limits: z_envelope_test's homed cases, which now assert no step before the alarm, and envelope_test. - cooling_intake.py, extcore.py, extdest.py, extlife.py and extmcode.py go whole; homeoff.py keeps only the camera-home helpers that cloud.mode-switch, setup.check-envelope and their meta-tests use. - The helpers only the removed tests used go with them. - exthost.armed-freeze still runs the cloud suite's dark-print helper, whose latch checks still run; its description says so. It now requires cooling.floor-and-warm-up, the dark print's own prerequisite, in place of the removed cloud.dark-print. - HOST_TESTED: forgectrl src/holds.* (holds_test) and src/mcode.* (mcode_test), whose only catalog home left with these tests. - The meta-tests that replayed the removed tests go: test_cooling_intake_suite.py, the cloud replay cases and their fixture. The one that catches a false PASS stays and runs the dark print as armed-freeze does: a latch open at the button fails. - Text that named a removed test (exthost.motion-job's description and comment, test_baseline's docstring) no longer does. Proof: the coverage lint on a manifest from the recipe pins reports 0 uncovered paths and 0 host-tested row problems over 111 tests (its one failure is setup.check-lens's src/lensfind.* entry, which the forgectrl pin bump clears); pyflakes adds no finding; the gate self-check refuses an empty artifact cleanly; the forgetest host suite passes under Linux (547 tests); the catalog loads with 111 tests after armed-freeze's description edit. Acceptance: the catalog hash moves, so the next image opens a new campaign. Every remaining test in laser.py, motion.py, cloud.py, cooling.py, exthost.py, homeoff.py and bedsize.py moves its fingerprint (their modules' shared text changed); exthost.armed-freeze moves by its requires.
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.
