The focus burn answers the wizard's home prompt with HOME from a dict, and the wizard takes the operator's word the same way: nothing reads where the head stands. A read at that prompt places nothing either: the wizard restarts the controller before it, and a fresh controller drops the X/Y reference. The one read with meaning comes before POST /wiz/laser.focus/start, under the campaign's own controller, when a manual home references X and Y: with manual_home_x and manual_home_y blank or 0, it is the one provider that declares X0 Y0 at the gantry stops. head_at_home(ctx), called after the ready gate and before anything starts, waits up to 10 s for a /status that serves a position (a transient miss is not a stop; ten seconds of none fails the test before any energy), records the read as head_at_start (pos, homed_axes, home_source, judged), and judges the head at X0 Y0 within HOME_TOL_MM (0.05 mm) when homed_axes carries X and Y and home_source is manual: off its home, the test fails before any wizard start, so no controller lever is touched. Unreferenced, the head's place rests on the operator's word at the ready gate, the log says so, and judged is False. The HOME answer and the steps stay; the description names the read. The strict form, a manual home before every focus burn, is a procedure the operator must add to every campaign; this change records and judges what it can read. Proof: tests/test_setup_burns.py, the Unit tests step of forgetest-ci.yml (python -B -m unittest discover -s tests), 22 tests OK on Windows and on Linux, with tests/test_setup_dark.py (20 OK) and tests/test_laser_dwell.py (10 OK). The scripted daemon's /status carries homed_axes 7 and home_source manual: at X0 Y0 the burn runs and the evidence carries the read with judged True; at X 12.5 the test fails before any start, with no burn started, no /controller/ lever posted, and the settings as found; unreferenced (homed_axes 4, home_source startup) the burn runs with judged False. pyflakes reports no undefined name. Negative control on a scratch copy: with setup_burns.py as it was before this change (the HOME answer alone), the X 12.5 case burns (Failed not raised) and the two evidence cases find no head_at_start; the three tests catch it. Acceptance: setup.focus's fingerprint moves (its own text and setup_burns.py's shared text); no other suite module imports from .setup_burns, so nothing else moves. The next campaign runs setup.focus with the head's place on record.
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.
