forgectrl's firmware paths now read an archive's product and take firmware only (fwproduct.c). The upload route was not exercised by any catalog test; this one is its door. Archives made on the spot with the machine's own fwup go to POST /update/upload as a multipart form: an extension package unsigned, one signed with a throwaway key, and one that carries a task are each refused with 400 "this archive is an extension package, not firmware" and nothing is staged; an archive of another product is refused as not firmware; one whose product is ForgeFIRM firmware is taken as the unsigned upload it is, and the staged file is removed. Nothing is applied: the apply calls the same gate before fwup -a, and its proof is the daemon's host test, because a catalog test that could fail there would write a slot. Proven. On the bench reference, image 20260920211625 with the gated daemon and this file mounted over the image's: update.product-gate PASS, and update.slots-and-signature PASS beside it (the signature refusal still comes first). Against the image's own daemon, which has no gate, the test fails on its first upload (200), and its cleanup leaves nothing staged. The unit suite passes (422) with no undefined name. Acceptance. update.product-gate covers forgectrl's src/fwproduct.* with the update sources.
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.
