1. When removing the hot end of the print head, you must check whether the print head is in place when reinstalling the hot end. (If it is not installed in place, the hot end nozzle may scrape the hot bed).
2. Note: Do not insert the hot end cable in place as shown in the left picture. Please insert the hot end cable in place as shown on the right. (If the hot end cable is not installed in place, it may cause the hot end heating failure).
