ScottW514 f74382984c exthost.motion-jog: a package moves the machine, watched
A new catalog test for the one capability that moves the head. The
reference package is installed with motion.jog and jogs on the test's
word, through a file the service watches, so the motion happens at a
moment the test chose and can be witnessed while it does.

What it proves on the machine: the host's credential is 0600 and root's
and holds motion.jog and not a camera; a jog past the bounds is refused
by the host with the machine never asked; the package's jog moves the
head and the head accelerometer sees it; and across the whole of it the
laser latch stays locked and the emission witness stays at zero. The
head is jogged back to where it started.

The laser check reads the field names the machine actually publishes
(laser_locked, laser.emission_samples). The first version of it asked
for names that are not in /status, so it compared None to None and could
not have failed.

Proven. The unit suite: 451 tests. On the bench reference, image
20260921220023 with the cross-built daemons mounted over the image's:
exthost.motion-jog PASS, and exthost.service and motion.port-jog PASS
beside it. Against the image's own daemons it FAILS: the route is 404.

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.
