The cloud client changes (python3-gfhardware: the latch unlocks at the run and nowhere earlier, the warm-up is supervised, a live feed must land and finish, fire needs a power byte first, the homing runner always stops). This commit carries the catalog tests that hold the part the bench can see. forgetest/forgetest/suite/cloud.py: - cloud.dark-print (new, kind operator, one press, dark by construction) replaces cloud.verdict-hold. The print arms on the press, waits for the engine's acknowledgment and runs: the laser latch is locked at the button and through the wait, unlocked only for the run (immediately before it starts), locked again when the job ends, and the print completes. The engine's own warm-up release stays proven by cooling.floor-and-warm-up. - cloud.verdict-refuse (new, kind operator, one press, dark): the start gate far above the coolant and cloud_hold_max_s at its minimum keep the armed print under the warm-up past the bound. The client waits with the latch locked (sampled every two seconds), cancels at the bound with its own log line, never runs, closes the armed window, and the print ends ':cancelled'. The settings are restored. - cloud.verdict-hold is retired: its release rode the loop heater at the flow-check duty against a gate one degree above the coolant, inside the upstream reading's noise band, and its run hovered for minutes with the engine's "warm-up stalled" line in the log. The two tests above prove the client's contract without the thermal race. - cloud.oversize-stream already reads cnc/streaming back at both ends of the run, which is the readback the client now insists on. A forced streaming write failure has no seam on the board (the write goes to sysfs as root) and stays a host test. tests/test_cloud_suite.py follows: excerpts and failure cases for the two new tests in place of the retired one's. Proof. Host: the forgetest unit tests. Bench reference: cloud.dark-print passed (locked at the button, unlocked in the run, locked after, ':completed'), cloud.verdict-refuse passed (held 60 s, 31 latch samples all locked, ':cancelled', settings restored); motion.deadman's kill during $H ended the runner on SIGTERM alone; and the retired cloud.verdict-hold passed once more on the new client before it went (the latch locked through an 8 minute warm-up hold, the release ran the print to completion).
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/).
Start here

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.
