The sheet handed the bench actuator every press after the operator's presence press, and the actuator pressed every time - into nothing. On the bench reference all six cards were pressed before the card asked: the frame by 8 s, the focus by 33, the floor by 10, the dose curve by 8, the corner by 9, and the flow-load card by 69. The operator then pressed all six himself, which is the opposite of what the ready gate promises. arm_press() waits for hw.button_lit(), which is true when any button LED is on, and burn() started that wait before run_check had even started the wizard. The button is lit through parts of a card that are not the arm - the lens reference, the program on its way to the controller - so the wait ended at once, the press landed before the job waited for it, and the thread was gone by the time the real cue came. forgectrl uses the same predicate but only inside the job's own sample callback, with the tube still dark, where a lit button does mean the arm. The machine already says when it wants the press: a live check opens a `press` wait prompt at that moment, and run_check sees every prompt. It now presses there, through a new Ctx.press_now() - no LED read, no waiting thread, no timing guess. That retires the per-card lit-timeout column of CARDS, which existed only to give the flow-load card's coolant settle enough room for a wait that was reading the wrong thing. The four grbl-driven arm_press() callers in laser.py and cooling.py are left as they are: they call it with the machine idle and its LEDs dark, so the level read is the edge they mean. The same shape would bite them if that ever stopped being true. Pin: forgectrl 0.1.15 (6e69479, the flow-load tail ending at the coolant peak and the way out of a finished setup page). Host-proven: 357 forgetest unit tests, including two new ones - the actuator presses on the prompt with button_lit stubbed false throughout, so the LED is provably not consulted, and the press falls to the operator without a takeover.
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.
