OMTech 80W CO2 — Genuine Leather (Veg-Tan, ~3mm)

Equivalent to ~10mm/s. From LightBurn forum (forum.lightburnsoftware.com/t/leather-engraving-and-cutting/98726). User reports 10mm/s at 45% on 50W OMTech — scale slightly for 80W by increasing speed to 12–14mm/s (720–840mm/min) at same power. Use 1 pass. Moderate air assist to avoid scorching edges. Thicker leather (4–5mm) may need 2 passes.

Equivalent to ~150mm/s. From LightBurn forum (forum.lightburnsoftware.com/t/leather-settings-pictures-attached/31830) and OMTech leather guide (omtech.com/blogs/tips/best-laser-engraving-leather-settings). DPI: 300 LPI. Low power prevents burning through. Vegetable-tanned leather gives best results. Chrome-tanned leather releases toxic fumes — confirm leather type before use. Light air assist only (5–8 PSI).
