The GRBL driver's emission gates change (grblHAL-glowforge: the per-tick fire gate, the latch with an owner, the cooling verdict's two tiers, and the arm-flow gates). This commit carries the host rules and the catalog tests that hold them; the driver commit follows, because its CI fetches these harnesses unpinned. scripts/bench/laser_stream_test.py: - Rule 24 is the verdict's pause tier: the client holds the job under the open window, the first deceleration runs lit to the stop (the dark lead before the stop is at most 1000 ticks: the producer's lead plus one shipper period), a resume under the standing verdict moves dark and is held again, the clean verdict resumes lit with no press, and the latch sideband carries only the arm's unlock and the program end's lock. - Rule 25 is the fail tier: AIRFLOW mid-cut ends the job with ALARM:3, the stream ends dark well short of the line, the sideband ends on the lock, and a resume under the clean verdict that follows resumes nothing. - Rule 26: a sender change mid-M3 holds the job with the deceleration dark: the gate follows the window on every tick. - Rule 27: a verdict that goes stale holds the job at the cache's own expiry, lit to the stop, never a poll later; the engine's return resumes lit. - The stand-in engine publishes the verdict name and has a stale mode; the session steps gain expect_text, reconnect and a wait_state timeout; every session reads the latch sideband (GFSINK_LATCH_LOG). scripts/bench/laser_lifecycle_test.py: - Rules 11 to 15: the pause tier resumes with no press and no prompt, the fail tier ends the job and nothing resumes it, a sender change during a re-arm cancels it, a jog does not hold the window open, and a press counts only after the button has been seen up. The stand-in engine takes a live verdict dict. start_armed_move waits for a fresh prompt and a fresh armed message: a press that lands before the wait has begun is not consent, and the old stale match let one land early. forgetest/forgetest/suite/laser.py: - laser.verdict-cut (kind live, one press): a 40 mm M3 line; the test pauses the daemon for 3.5 s so the verdict goes stale (the settings route is idle-gated and the engine reloads its gates at a session start, so no setting can trip a pause mid-cut; the crash tiers need a physical knock). The controller must hold with the SoC latch and the hardware button latch both clear in every sample, emission must read 0 before the resume, and the clean verdict must resume the cut lit with no press and no prompt; M2 disarms as usual. - laser.armed-kill asserts that the respawned controller comes up with the latch still locked. Proof: both harnesses pass against the driver change on the host, and the forgetest unit tests pass. On the bench reference, laser.verdict-cut passed with no gap in the cut (held at +1.71 s after the pause began, both latches clear in every sample, emission 0 at +2.06 s after the hold, resumed lit at +4.0 s with the beam detector 678 counts over idle, kernel drift 0.0 mm, disarmed 0.1 s after Idle) and laser.armed-kill passed (emission 0 at +1.8 s after the supervisor's stop and +2.1 s after the SIGKILL, latch locked, respawned with the latch locked, button dark). Two earlier verdict-cut runs shaped the driver: a pause that locked the latch resumed dark, because a lock sets the hardware button latch, and a hold taken a poll after the gate closed left a several-mm gap. Catalog: one test added and one extended; both cover src/** of the driver through the existing laser covers.
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.
