Topic: DaVinci Jr. Strange Extrusion Problem
My XYZPrinting DaVinci Jr is having extrusion problems When I start to print, the printer will extrude large amounts of plastic, but eventually, only a small amount will be extruded on the back of the bed. Eventually, the printer will only leave trace amounts of plastic behind. I tried to clean the extruder gears and the hotend, but the printer will still do the same thing. Also, this plastic seems quite lumpy and irregular.
