The 3D printer does not work. Follow these steps to troubleshoot the problem:
1 First, check if the head of each part is loose, connect with loose parts, and conduct electricity test;
2 If the fuse in the power socket is damaged, if it is damaged, replace it with a power test.
3 Whether the power supply is damaged (pay attention to the power supply voltage): If there is no projector screen after the fuse is broken, the power supply is considered damaged, and a new power test is performed after replacement.
