Rule 18 proved a typed $35 is overwritten at the arm and the ladder
renders through the floor key, but took the shipped settings on faith:
the harness mirrors $31 = 0 and the board's 10 % floor as constants. The
catalog's laser.power-floor read them off the machine; it can leave the
catalog once the host does.
- The floor-derived session reads $$ on the fresh controller (no floor
key: the shipped default) and again after the arm overwrote the typed
$35. Both reads must show $31 = 0 (the floor, not $31, sets the bottom
of the S range) and $35 = the board's floor, and that floor must land
at PWMSAR_FLOOR_MIN (12) or above.
- A set floor key is laser_arm_test.c case J's (12.5 honored, an
out-of-range key falling back to 10, 0 honored). forgectrl keeps no
default for laser_floor_density: an absent key is the controller's
own floor, so there is no second default to compare.
Proof: laser_stream_test passes whole on a null-sink build of the
grblHAL-glowforge working tree under Linux ("$31=0 and $35=10 (PWMSAR
12) fresh and after the arm"). A control session with a floor key of 5
reads back $35 = 5 both times through the same parse, which rule 18
would fail. pyflakes is clean.
Acceptance: none. The harness runs in grblHAL-glowforge's CI.
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.
