Guide for Material Positioning
When positioning a flat piece of Material on top of the grating
You will create small section of a vacuum inside the tiles of the grid when the air filter is turned on. This vacuum is not strong enougth to hold onto the material, but there will be more deposites on the grid and a visible grid pattern will appear below the material.
To prevent this, small T-pieces can be layed down to allow the air to move unobstructed below the material. It is recomennded, that the T-pieces are the same Material as the one you will cut, to prevent different colored deposition, when one of the T-pieces is cut accendentally.
