The Snapmaker Ray 40W is a 40W diode laser engraver with a 400×400mm work area. This page lists 55 community-tested settings covering speed, power, passes, air assist, and DPI across a range of materials.

The Snapmaker Ray 40W is the higher-power version of Snapmaker's dedicated laser line. At 40W diode it cuts 6mm basswood, handles thicker acrylic, and engraves at higher speed than the 20W. LightBurn compatible. A strong choice for production-level diode work — fast enough for small Etsy batches, enclosed enough for home studios with Snapmaker's air assist module.
