xTool M1 — Genuine Leather (1–3mm)

Leather needs moderate power and moderate-to-high speed to avoid burning. Community-confirmed range: power 20–60%, speed 60–80mm/s, 1 pass. ShawnMosch M1 guide documents power ~20% at 80mm/s for light surface mark on patches; Keeping It Simple Crafts used power 60% for a deeper engrave on thick genuine leather. Start at 40% power / 70mm/s and adjust — leather type (veg-tan vs chrome-tan) significantly affects results. Veg-tan takes deeper marks; chrome-tan burns faster. Do NOT use air assist for leather engraving (spreads char into the grain).
