Issues related to importing fill elements

If you have a vector file that has both components FILL and Line you should export them in different colours so Lightburn can apply different layers

if not possible, you need to select the fill shapes, and move them to a different layer in lightburn

A layer = A “job type”
so if you have fill and line you need at least 2 layers

Images are validated by the “color” when converted to B&D/GrayScale
White will represent no engraving - black will represent max power (Within layer parameters)
So you do not need to remove background if said background is white.
