The amount of available materials is overwhelming, so below you can find materials we have tested and result in good quality cutting or engraving.
The darker the material, the better it absorbs laser light, therefore it can be cut/engraved faster.
Laser light is focused through the lens to one small spot, which has a density (cutting power) around 1-3 mm away from the bottom edge of toolhead. Adjust the Z-axis accordingly (try burning calibration pattern from LCD menu).
Bright materials bounce the laser light back, so engraving and cutting might be difficult or even impossible.
