forgectrl's job runner (POST /job, and the dose-curve recorder and the sheet wizards moved onto it) needs a test of a posted program, and nothing in the catalog ran the recorder's start: only its refusal and its status. motion.job posts programs the way a client does, as a multipart form. A program with a $ line and a job with no name are refused with 400, and a job beside the suite's own Grbl client with 409, each with nothing moved. A dark program (out 20 mm, a dwell, back) then plays: /status names job:forgetest as the lease holder of kind sender, GET /job reports it running, and a second job, a port jog, and a settings write are each refused in the job's name. At its end the record says done with every line and the runner's own M2 acknowledged, no discharge and no LASER_ON sample, the kernel's counters saw the 20 mm and are back where they began, and the lease is free. POST /job/abort stops a 40 mm move short, into the controller's alarm state, with the lease free. A job sent into the alarm fails at its first line with nothing moved; the same job with unlock=1 clears the alarm and returns the head. laser.recorder-dark starts the recorder and never presses. While the controller waits at its arm: the recorder holds the machine as a sender, GET /job shows its run (not a posted program's), the floor and the curve read 0 and off, POST /job/abort refuses to stop a run it did not start, a posted job is refused in the recorder's name, and two seconds of witnesses stay dark. POST /curve/stop ends it: stopped before the ladder fired, the lease free, both laser keys as they were. The ladder begins at the controller's X0 Y0, so the head is returned by a posted job. covers: setup.sheet and forgectrl.lease name src/jobrun.*, since the sheet wizards stream through the runner and the recorder's refusal comes from it; setup.sheet names src/lease.* for the hold its jobs take inside the wizard's. Proven on the bench reference, the job runner's daemon hot-deployed over image 20260920130136. motion.job: PASS; the kernel saw 20.000 mm out and 0.000 back, 6 lines with 7 sent and acknowledged, every witness zero, the abort at 9.83 mm of 40 into Alarm, the unlocking job with its $X and its M2 the two lines more. Its first run failed, and found a defect in the daemon and not in the test: the record said done with the head 0.19 mm short of its end, because the controller acknowledges M2 before the pulse engine has played the last of its ring. The runner now waits for the kernel to be idle, and the test passes unchanged. laser.recorder-dark: PASS; the controller reached its arm wait, 16 samples dark, the stop left the controller Idle and the head where it was. setup.sheet: PASS with the operator at the machine. forgectrl.lease: PASS. The unit suite passes (420) with no undefined name. Acceptance. These two tests are the gate for forgectrl's job runner, with setup.sheet for the sheet wizards' side of it.
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.
