๐ 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 |
