If you use the printer frequently, small particles of plastic and fiber may accumulate in the internal space. From time to time clean the printer platform from accumulated particles and dust with a microfiber and a vacuum cleaner.
The glass of the buildplate will inevitably accumulate particles of plastic and fiber, fixing varnish or glue. To improve the adhesion of the part during printing and the quality of the first layers of the product, it is recommended to clean the surface of the glass before each print with a damp cloth.
