homing.cloud-offsets, setup.check-envelope and cloud.mode-switch let the
service move the head, and ended with it where the service left it: at
the camera home, or, in cloud.mode-switch, under the camera, where the
service's re-hunt had taken it. Each told the baseline the counters had
been re-zeroed at the starting position, so the hand-back saw nothing to
do. No counter reading can say where the head was found: every service
motion zeroes the counters at its start, and the home and every
controller start zero them again.
suite/homeoff.py now holds the helpers for a test that lets the service
move the head:
- session_travel sums a client's own record of each motion's end ("end
positions (x, y, z)", the counters the motion zeroed at its start, in
x8 steps, the one mode a service motion runs at). A motion with no end
on record, or a log rotated under the run, leaves the travel unknown.
- camera_home_return drops the camera home, jogs the head back by the
session's travel plus what the counters read since the home, starts
the controller once more so the counters read zero where the head
began, and tells the baseline. cloud_mode_return does the same for a
stay in cloud mode, from the cloud client's log.
- A travel that cannot be known fails the run and moves nothing. A
hand-back that fails while the test is already failing is logged, and
the test's own failure is the one reported.
- judge_whole_motions fails a homing motion that stopped short: the
position declared after it is false.
cloud.mode-switch imports the helpers inside its function, so no other
cloud test's fingerprint moves. Its cloud stretch no longer goes through
return_head, which read 0/0 after the controller's start and left the
head under the camera.
Proof: tests/test_camera_home_return.py, 15 cases on the machine's own
log lines (a session stopped short, a whole three-motion one, a cut log,
a refused motion, homed and unhomed counters, a restart since the home,
the first failure winning). tests/test_cloud_suite.py's mode-switch fakes
now zero the counters and remove the anchor at a controller start, write
the anchor at the home, and move the counters on a jog: 10 cases, a
failed hand-back that must not hide the test's failure among them.
forgetest 498 OK. On the bench reference, with the driver and the runner
fixes: homing.cloud-offsets, setup.check-envelope and cloud.mode-switch
PASS, each ending with the head where it was found; cloud.mode-switch
jogged its cloud stretch 246.06/139.01 mm back with the counters across
the jog agreeing, and every baseline was clean.
Acceptance: the three tests are the change; their fingerprints move 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.
