ScottW514 fc6b7797af forgetest: the shared judges' comments say why puls.py is one
The comment over SHARED_JUDGES in catalog.py said that every test runs
through all four judges without importing them, puls.py among them, and
the comment of test_a_shared_judge_edit_moves_every_test said the same.
No test runs puls.py but the three that print the dark job
(cloud.lid-interlock-abort, cloud.oversize-stream and
exthost.armed-freeze, through offline_job), and suite/cloud.py imports
it with `from .. import puls`: it is a judge because the sibling walk
does not follow that import, as the Acceptance page of the site says.

Both comments now say that every test runs through runner.py, hw.py and
baseline.py with no import to follow, and that puls.py comes in by a
package import the walk does not follow. Comments only: SHARED_JUDGES
does not change.

Proof: forgetest-ci "Unit tests" (`python -B -m unittest discover -s
tests -v` in forgetest): test_manifest.py runs 39 tests, OK, on Windows
with python 3.14 and on Ubuntu 24.04 with python 3.12. The only import
of puls in the package is suite/cloud.py's (grep). pyflakes reports no
undefined name.

Acceptance: none. catalog.py is the registry and in no fingerprint, and
tests/ are in none (source_sha of 43 of 43 unchanged).

OpenGlow / ForgeFIRM firmware for Glowforge

BETA

ForgeFIRM is in beta. Every release below 0.1.0 is a beta release. It's stable, but you may still hit the occasional bug, 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.
