The perforated plate is an essential part of the platform, which increases adhesion of the model to its surface during the whole printing process. However, the perforated plate can become worn over time and covered with irremovable material remains, and influence the quality of 3D printed parts. Once you notice visible signs of wear and tear, consider replacing the perforated plate. Also, the plate replacement is needed when your printer displays the error message #030 but the small platform connector is plugged in properly.
