# OpenGlow/ForgeFIRM Firmware for Glowforge
|
|
|
|
Open-source firmware for Glowforge brand CNC lasers. ForgeFIRM replaces the
|
|
cloud-dependent factory software on the **stock control board** — no hardware
|
|
modification — and gives the machine a local controller, a local web control
|
|
panel, and a standard Grbl interface.

|
## What it does
|
|
|
|
**Two controller modes, selected in the web panel and switchable while the
|
|
machine is idle:**
|
|
|
|
* **GRBL mode** — [grblHAL](https://github.com/grblHAL) runs on the machine and
|
|
speaks Grbl 1.1 over TCP port 23, so LightBurn, UGS, and cncjs drive the
|
|
laser directly. Motion runs on the board's own hardware step engine (SDMA +
|
|
EPIT), fed live by the planner. M3/M4 dynamic laser power, coolant-flow
|
|
verification, over-temp holds, and an operator button press to arm the laser
|
|
for each job.
|
|
* **Cloud mode** — the machine presents itself as a stock Glowforge to the
|
|
Glowforge web service, so the phone and web apps work as they always did.
|
|
Optional, and off by default. GRBL mode jogs and cuts without it; the one
|
|
GRBL-mode function that still reaches the Glowforge service is
|
|
camera-referenced homing (below), until limit-switch homing lands.
|
|
|
|
**Around both modes:**
|
|
|
|
* A **web control panel** on port 8080: machine status and position, coolant
|
|
and fan telemetry, safety-switch states, camera view, machine settings,
|
|
hardware diagnostics, firmware updates, and boot-slot management.
|
|
* **Camera-referenced homing**: `$H` from any sender runs the factory-style
|
|
camera homing cycle through the Glowforge service (a Glowforge account and a
|
|
live service session are required for `$H`; everything else in GRBL mode
|
|
runs without them), and the machine records where it is.
|
|
|
|
## Hardware
|
|
|
|
The control board is common to Glowforge Basic, Plus, and Pro. The 5 MP
|
|
(OV5648) camera modules are fully supported; the 8 MP (OV8856) modules found in
|
|
"HD" units bind but do not capture yet — see the camera note in
|
|
[kas/README.md](kas/README.md).
|
|
|
|
## Safety
|
|
|
|
**These machines contain a CO₂ laser: it burns, blinds, and starts
|
|
fires.** Never defeat the lid switches or interlock. Never leave a
|
|
running job unattended — keep a fire extinguisher within reach. Read
|
|
[Before you cut — safety](docs/LIGHTBURN.md#before-you-cut--safety-read-this-first)
|
|
before your first job, and the
|
|
[Regulatory and legal](INSTALL.md#regulatory-and-legal) section before
|
|
installing. [How the laser safing works](docs/SAFETY.md) describes the hardware
|
|
safety chain and the software gates ForgeFIRM stacks on it.
|
|
|
|
**A very important warning: this is experimental software. Use of this software
|
|
could seriously maim or kill you or others, and voids your warranty. It is not
|
|
affiliated with or endorsed by Glowforge. Use it at your own risk.**
