Three acceptance tests broke on the WI-4/WI-5 firmware, all from a behavior a change moved and no test tracked. motion: soft limits are armed after a home (the driver's, since the bed has no switches), so a jog past the bed is refused with error:15 - and grblHAL then answers error:15 to every following G-code line, across a fresh connection, until a blank line acknowledges it. A prior test's or the baseline hand-back's rejected jog left that latch, and the next test's first move failed with a stale error unrelated to the move. clean_slate now clears it with a blank line before the first move. The four "send G1, sleep, check Run once" sites are replaced by start_move, which waits for Run on a bound and, when it does not come, names the reply, the state, the drained messages and a forgectrl snapshot - the capture that turned "the move did not start" into "answered error:15". cooling.fire-watch-tiers: the FIRE fail tier now stops the controller through the supervisor and starts it again, so leg 2's Grbl connection dies mid-leg. It now records the pid, reads FIRE from the engine and the latch from sysfs, waits out the restart, proves the supervisor logged the fail-tier stop, and opens a fresh session for the legs that follow; src/super.* added to its covers. Proof: full forgetest host suite green; coverage lint clean (90 tests); bench reference on the dev image, unattended queue: motion.* and cooling.* pass, cooling.fire-watch-tiers and cooling.fail-tier-stop pass with the button-lamp driver fix (grblHAL-glowforge).
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.
