ScottW514 fb956971b7 LASER_PWM waveform gate PASSED - scope-verified on the physical pin
Direct PWMSAR duty steps with the machine in the locked state
(controller stopped, cnc disabled so steppers are unpowered, laser
latch locked, lid closed; laser_on_sampled stayed 0 throughout).
Measured on the pin: 25.0 us period / 40 kHz stable across the full
duty range; 50/25/75 percent confirmed visually; low end
cursor-measured 6.4 vs 6.3 percent commanded (PWMSAR=8), clean pulse.
Matches the register-level audit numbers (divider 13 x 127 counts).

Adds pwm_sweep.py / pwm_hold.py to the bench kit and records the two
remaining pre-live-fire gates (1-tick laser drop at underrun via the
stream path with FIRE observable under a locked latch; interlock
readback semantics) in BRINGUP.

OpenGlow/ForgeFIRM Firmware for Glowforge

This repository contains opensource firmware for Glowforge brand CNC lasers.

Roadmap

  • Base image that supports all Glowforge hardware (complete)
  • Support Glowforge web service - Python implementation (mostly complete)
  • REST API w/ G-Code support (in progress) Stalled
  • Browser-based GUI (pending) Stalled

This project is for experimental purposes only, and is not supported or endorsed by Glowforge.
