xTool S1 — Genuine Leather (1–3mm)

The 40W module requires much higher speed than lower-watt machines to avoid burning leather. Recommended community starting point: 40% power / 300mm/s / 1 pass for surface engraving on veg-tan. For chrome-tan or thinner leather, reduce power to 25–30%. For deeper engrave add a second pass rather than slowing down (prevents heat buildup). Brildor xTool leather guide recommends always running a test swatch and adjusting power in 5% increments. Do NOT use air assist for leather engraving.
