Question #: 14749

Question: My Z axis motor changes direction in the middle of an operation. It starts out correctly, than in the middle of an operation the Z axis goes in a negative operation instead of the positive direction. When I reset after this having the Z axis go down it goes up, and then asked it to go up it also goes up?

Current Solution

That is a simple loose connection. How the direction connection works. There is a high state (5v), and a low state (0V or ground). If the down operation is the high state and the connection is not good, the connection could go to a low state and then go in the opposite direction.

Check the connection and confirm it is secure.
