I have a prusa i3 printer. This printer was printing perfectly before this happened. Now the first layer is printing to thick. If it is filling in a large object it may stop extruding material. When it gets to the end of the print layer it will not step up to the next layer and it runs over the first layer ruff with a dragging sound as if the extruder is to low. If it steps up the right way for a few layers it will evenly run a layer more then once and stop the extruding of material.
