The new Phenom L I purchased yesterday ran into an issue. While following the set up, the arm was moving properly. When I tried to print something, the Z-axis arm stopped working. When trying to move the arm, the motor rattles violently and it does not move up or down. When I turn the printer off, I can raise the arm by hand no problem.
Here’s a video of it shaking violently when trying to move up or down:
Does anyone have any ideas about this issue?
