# Laser Cutting & Engraving Poster

## What
A1 landscape workshop poster covering laser cutting end-to-end — beam physics, laser types (CO₂ vs blue diode vs IR vs fiber), machine anatomy diagram, safety, a 14-material suitability matrix, 20W-class settings cheat sheet, LightBurn workflow (layers 0–30, T1/T2 tool layers, Line/Scan/Image modes, tabs), design & joinery (kerf compensation, finger joints, nesting), calibration test grids, banned materials, 12-step workflow, and troubleshooting.

## Build details
- Single-file HTML design (light theme, print-tuned) → rendered to PDF with Playwright/Chromium headless at exact A1 landscape (841 × 594 mm, one page).
- Content cross-checked against DAJA A6 Pro 20W official specs, LightBurn docs, and community databases (bonnycreations, MetalEraser, Diode Laser Wiki).
- All speed/power values labeled as starting points — every machine differs, test grid settles it.

## Files
- `Laser-Cutter-Poster.pdf` — the poster (print-ready, A1)
- `Laser-Cutter-Poster.html` — editable source design
