The following settings should be used as a guide. By decreasing the speed or increasing the power, the engrave can be made deeper.

Little Red has a laser accuracy of 0.1mm, This means that your engrave at 0.01mm will take 10x longer than a engrave at 0.1mm (And will look the same), ITs a waste of your time and money. Big Red Is not designed for high detail engraving and you wont get the result like you do on Little Red.

Rubber Stamps

To make a rubber stamp with the laser engraver you need to use the laser-safe engraving rubber (ask atrophy), you need to use the Grade Engrave setting to ablate the material but leave sufficient support material around small features.
**Important: Remember to <span style="color:red;">mirror</span> your vectors before cutting!**
