motion.soft-limits homed only when the machine was not homed already, and then with whatever homing_mode the machine had: it counted on the home cloud.mode-switch used to leave behind. cloud.mode-switch now drops its camera home when it hands the head back, so the test started unhomed, and under the operator's homing_mode = manual its $H was a manual home, declared at once where the head stood (2.2 s, no web-service session), and the test failed on gfhome's missing completion line. When it did home, it left the head at the corner and the machine homed. The test now sets homing_mode = gfcloud and unsets the camera-home offsets for its run, so the envelope is the bed from the home corner, and always runs its own camera home, every motion of it judged whole (homeoff.judge_whole_motions). A setting is written when the controller takes it (it refuses one for a moment after a Grbl client closes). At the end the settings are put back as found and homeoff.camera_home_return drops the home and jogs the head back to where the test found it. The helpers are imported inside the function: homeoff imports this module. Proof: on the bench reference, image 20260925183749 with this file mounted, motion.soft-limits PASS: the camera home in 52.6 s, every motion completed; X max, Y max and X min refused with ALARM:2 and no motion, the jog past the bed refused with error 15, the move inside the bed ran and came back; the settings put back; the head jogged back 28.95/13.03 mm to where the test found it; the baseline clean. forgetest 499 OK. Acceptance: the test is the change; its fingerprint moves and no other test's does.
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.
