When I print, the Z-Axis will sometimes (not always) start to intermittently freeze. I have checked the threaded rod and it is well greased, I have also verified that the rod rotates without any resistance. Any suggestions on how to troubleshoot this problem?
Thank you for any help you can give.
I think I would try to switch the plugs on the circuit board on back. Z axis for Y axis for example and test. Then you can tell if its the motor or something else.
Or set up a fan to blow on the electronics. It can do that if the stepper driver starts to overheat. You can use a table fan to start with to see if it helps before wiring in a permanent one.

I just tried this. The step size with the y-axis motor/ z-axis driver is 10x larger and the z motor/ y driver is 10x smaller. I assume this is expected. No matter how much I move them both around, neither of them seem to freeze.
*edit*
Scratch that, the Y-axis motor on the Z-axis driver just stopped.

I set a fan up on it once a while ago and it did help (it wasn't a scientifically rigorous test but it seemed to help), however It did on occasion still freeze up. 
I adjusted the potentiometer on the driver counterclockwise and it seems to be running fine now. Thank you for the help!
