homing.manual runs two homes. With manual_home_x and _y unset, $H plays no byte and declares X0 Y0 (the checks it had). With 5 and 3, $H declares the head at minus them and jogs it to X0 Y0 before it answers: the sender is told the declared position, the kernel plays the move, Grbl and forgectrl read X0 Y0, and a jog behind the origin draws error:15. The test restores homing_mode and both offsets as found, and returns the head by what the machine read, so a move cut short still comes home. The change stays inside the test's own function. manual_home_test.py: case 7 is the offset's new meaning (declared at minus the offset, the move dark under a modal M3, the port's home, the clamps); a new case cancels the move with a jog cancel and expects it to stop short with $H saying where; case 8 reads the declared position from the sender's message. The bench README says so. Proof: manual_home_test.py ALL PASS against the driver change (ten cases), and its cancel case fails against a build with the driver's cancel hook left out. On the bench reference, fx14 with the driver change and this suite file in place of the image's, homing.manual PASS in campaign c-20260926000059-e731: with no offset no byte and X0 Y0; with 5 and 3 the sender was told X-5.002 Y-3.000, the kernel played 1067 and 640 steps, Grbl and forgectrl read X0 Y0, error:15 behind the origin; settings restored and the baseline clean. The forgetest unit tests pass. Acceptance: homing.manual is the test; its covers are unchanged (the driver's src/**, forgectrl's status and main.c).
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.
