LightBurn — Cut Settings and Layer Reference

LightBurn — Cut Settings and Layer Reference Quick reference for LightBurn's cut layer settings — what each parameter does and when to change it. Layer Types Core Settings Fill-Specific Settings Start Mode Pass-Through Mode Bypasses LightBurn's image processing — use for pre-dithered images or if you want exact pixel-to-dot mapping. Overscan Adds extra travel at the ends of scan lines to allow the head to decelerate before turning. Prevents dark edges on engraves. Usually 2–5% or auto. Air Assist Enable per-layer. Turn on for cuts, optionally off for light engraving to avoid blowing away ash patterns.
