LightBurn forum: K40 users report 250–300 mm/s at 8–9.5 mA (roughly 20–25% of a 40W tube) for anodized aluminum raster engrave. K40 Whisperer equivalent is ~6–8 mA on the dial. Black anodize works well; violet/purple anodize may not absorb the 10.6µm wavelength cleanly. Stock K40 typically has no air assist.

"This template made my slate coasters so much easier. 4×4 coasters from Michaels drop in easily and are easy to remove. Def worth it."
