When it receives from the computer the command to engrave a certain image, the laser head will move left to right above the board (with a determined speed) and it will emit the laser beam (with a determined power) only in the points that need to be engraved/burned (the same way a printer prints ink only in the places you want to print something). At the point way the laser beam touches the material this will melt, burn or vaporize, leaving a clear contour marking. This is called RASTER engraving.
Top view of the path the beam takes (red) when engraving a rectangle (black).
When an engraving formed of thin contours is needed or in the case of cutting (by following the cutting contour) the laser head won't perform as an ink-jet printer anymore (raster printing, point by point). Instead it will follow the vector contour. In the image below you can see the pathe the laser beam taker starting from the black point and folowing the arrows until it arrives at its starting point (or stoping at the end of the line segment). Usually red reprezents the cutting contour (greater power and slower speed) and blue reprezents the vector engraving contour).
This is the laser engraving/cutting in VECTOR mode.
This presentation will help you create your sketches/projects, choosing correctly the tipe and color of your lines.
Caution: don't use double lines for cutting (red) - it can lead to overburning of the material and errors in the equipments software.
Caution: we remind you that what will be engraved by the laser will need to be filled with black or shades of gray; thin lines that will be engraved in vector mode must be blue and cutting lines will be red (hairline, thin line).
