z axis motor spins clockwise fine but when it needs to spin anticlockwise it just spins clockwise

Masterhief

I have had the zonestar P802C since January and put it together no issues then I tested each motor and every motor connected to z axis port only spins in one direction no matter if it is set to go clockwise or anti clockwise it just goes clockwise starting to get annoyed please

That means the direction pin is not working. If you have a free motor socket use that instead. It is either a wrong pin number or a hardware defect, bus as I have no other reports about that I assume a hardware problem.
