๐Ÿ“‹ Material Recommendations
Material DPI Range Interval Notes
Wood (Engrave) 254-318 0.08-0.1mm Higher DPI rarely helps, wood grain limits detail
Anodized Aluminum 300-500 0.05-0.085mm Fine detail possible
Stainless Steel 500-1000 0.025-0.05mm MOPA can go higher
Acrylic 254-400 0.06-0.1mm Too high causes melting
Glass 300-600 0.04-0.085mm High DPI for smooth finish
Leather 150-254 0.1-0.17mm Lower DPI prevents burning
Paper/Cardboard 200-318 0.08-0.13mm Medium DPI, low power
