Z Axis will not go up

I had issue with my Mini+ few weeks ago due to filament feeding issue. Last weekend, I replace and fixed the feeding, but the new problem appeared: Z axis can't go up. I don't think it was an issue before the feeding issue. 

I updated the firmware to 6.1.2 yesterday. And then ran calibration. I noticed the calibration issue with changing the height and it did not lift the X axis. I manually lift the Z and it made some noises and vibration as it will not go up. It can go down with no issue. So, I ran Z Axis Test and it failed. 

I tried to use the chat with Prusa Tech support and for some reason, my chat queue were pushed 5 minutes to 25 minutes and I closed the chat - not worth waiting for. 

I'm posting here to see if anyone else have experience with that issue before I decide to replace Z axis motor.

RE: Z Axis will not go up

Try moving the Z axis using the menu. Not working? Swap the cables between the X and Z axes and try moving both axes using the menu. This will determine whether the fault is in the motor or in the board.

Okay, I swapped the cable. Z axis seems to be fine for some reason. But I do tested X axis using Z axis on menu and it looks fine. 

When I swapped them back to normal, I still having issue with Z axis. I'm thinking of taking it apart and clean everything up - lube the bearings. Then I will see if it's fixed or not.
