The heatbed cable is responsible for transferring power from the motherboard to the heatbed and perforated plate during platform calibration and printing process. The heatbed provides proper platform heating, whereas perforation on the plate’s surface increases adhesion of models during the printing process. Both of these factors highly influence the printing quality. Therefore, if you are unable to complete the calibration (the nozzle hits the perforated plate) or the platform heating is insufficient, at first you should check the heatbed cable for proper connection. If the cable is properly connected but you still encounter problems, you have to replace the heatbed cable. This manual shows how to properly replace the cable.
