What should I do if the 3D Printing Module doesn't move in the Z axis direction when printing?
1) Make sure all the cables, especially the Z axis, are properly and correctly connected to the controller according to the Quick Start Guide or the provided Connection Card.
2) On the Touch Screen, go to Controls > Jog Mode. Select Move 10 mm and then tap Z-, Z+. If the 3D Printing Module moves according to your operations, there is nothing wrong with your printer. If the 3D Printing Module doesn't move according to your operations, please go to step 3.
3) Turn off the printer, unplug the cable from port 5 and plug it into port 4, and then turn on the printer. Repeat step 2. If the 3D Printing Module moves according to your operations, there is something wrong with port 5. Please use the printer with port 4. If the 3D Printing Module doesn't move according to your operations, please fill in the warranty request on our website and contact firstname.lastname@example.org for assistance.
