💡 Tips for Rotary Engraving
- Test first: Always test steps/rev with a small mark before engraving the final design
- Taper positioning: For tapered cups, position the narrower end towards the chuck
- Surface prep: Clean the surface before engraving, especially powder-coated tumblers
- Speed reduction: Reduce speed 20-30% for curved surfaces compared to flat engraving
- LightBurn setup: Use LightBurn's rotary setup wizard after entering these values
- DPI consideration: Tighter curves have lower max effective DPI before overlap occurs
- Calibration: Use the calibration helper after any speed or setup changes
