ScottW514 b94c990bbc Leave the lens to the cloud client in cloud mode
cloud.verdict-hold printed to completion and then failed its hand-back on
head/z_mode=0. That job's header carried ZSmd 0, gfhardware's
set_mode_from_puls turns that into z_mode 0, and z_mode 0 is full step
(lenshome.c): the cloud client had set the lens the way the pulse file it
was playing asked. Nothing was left behind - the machine did what the job
said.

The baseline already skips nine attributes in cloud mode, for the reason
written above the list: the cloud client sets its own values for them
from every pulse header, and forcing the GRBL values under it would be
the baseline configuring another controller's machine. head/z_current and
head/z_mode are the same thing and were not on the list. They are now, in
cloud mode only; in GRBL mode the pair is still checked against 1 and 1,
which is the half of this an exemption could quietly break, so a test
holds it.

Host-proven: 89 baseline unit tests.

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.
