This page lists 59 community-tested settings covering speed, power, passes, air assist, and DPI across a range of materials. Always run a test cut on scrap material first — results vary depending on your material batch, focus, and ambient conditions.
The Snapmaker Ray 20W is Snapmaker's dedicated standalone diode laser — separate from their modular 3-in-1 printers. It has a 400×400mm work area, built-in air assist, and LightBurn compatibility, backed by Snapmaker's known build quality. At 20W it cuts 3mm basswood cleanly and handles wood, leather, and slate engraving well. A reliable mid-range choice for makers already in the Snapmaker ecosystem, or those who want a solid LightBurn-compatible diode from a reputable brand.
Should you buy the Snapmaker Ray 20W?
Best for: Snapmaker ecosystem users and buyers who want Snapmaker build quality in a dedicated diode laser. LightBurn compatible, built-in air assist.
Skip if: You don't need the Snapmaker ecosystem premium — Sculpfun S30 Pro or Atomstack A20 Pro offer similar specs for less.
