ScottW514 eb9e61d3c6 motion.soft-limits: past the envelope the home armed, and stopped before it fails
After a home the driver's X/Y envelope reaches to the far edges the bed
check measured (envelope_x_mm, envelope_y_mm, held by
gfhome_clamp_envelope_mm to 50 mm up to the travel plus 30 mm), and to
$130 by $131 only on a machine that was never measured. The test aimed
its refusals at $130 + 5 and $131 + 5, which holds only on an unmeasured
machine. On the bench reference, measured at X 508 and Y 288.925, image
20260928153805's campaign sent G90 G1 X500 F600, the controller rightly
ran it, and the failed check ended the test before its soft reset, so
the head drove the whole 476.6 mm while the restores were refused with
409 for 40 s; the jog check after it would have run a 500 mm jog the
same way. The test now takes the far edges as the driver does and sends
each move and the jog 5 mm past them, and it stops a move that was not
refused (the soft reset, now ahead of the checks) and a jog that was not
refused (the jog cancel) before it fails. The judgment is unchanged:
ALARM:2 with no kernel motion, error 15 for the jog, a move inside the
bed runs.

Proof: pyflakes clean. On the bench reference, image 20260928153805 with
this suite bind-mounted, the test passes: the far edges 508 and 288.925,
G90 G1 X513, Y293.9 and X-1 each refused with ALARM:2 and 0.0 mm of
kernel motion, the jog refused with error 15, the move inside the bed
run, the head handed back where it was found, the baseline clean.

Acceptance: the change is motion.soft-limits itself; its own function and
description carry it, so no other test's fingerprint moves.

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.
