If you haves swapped drivers and swapped cables motors and the problems has stayed put then could be a board.
It can be frustrating. Damaged an arduino board when setting mine up fortunately had a spare on hand.
Good luck man press on .

@Tin Falcon. Thanks but I've already done that. I've tried 3 known working drivers in the Z. With each driver I plugged in X then Y. I also tried the Z motor in X and Young etc. Having done this ive concluded that the problem is not the Z motor, nor the wiring. It's not the drivers. There is no question that the problem must lie with the Z pins on the board. Or, that specific area of the board. I may be wrong. I'm certainly no expert but I simply cannot think of what else it might be.

Try switching the Z and x or y motors and try to jog.
Look for the simple stuff first. Could be a cable issue

So, my best noobish guess is that the Ramps is damaged. There is defo no question that my problem lies with the pins on the board for the Z axis. Unfortunately, I wouldn't have a clue how to test these connections for bad soldering etc. with a Multi Meter. Visually, under magnifyer the solder joints seem OK but, of course this doesn't really mean anything unless I tested them. Thankfully I didn't pay too much for the board so its back to Amazon I go.

Nope, I'm sure its not that. I'm using Anthems settings from here, http://www.soliforum.com/topic/15273/ho … -ramps-14/. Up until today those settings worked fine and I've already checked them and they haven't changed.

OK. This is strange. I'm using Repetier host to control my (ramps with marlin) printer which I'm busy setting up. Today, whilst trying to set the z offset, my Z stepper started acting weird. It was OK before today. Using Repetier, I was jogging the Z axis. The options are 10, 1 and 0.1 mm increments. For no reason, it started making a loud whining noise when I tried moving it 10 mm. The motor is showing tiny shuddering motion back and forth but that's it. The 1mm and 0.1mm work fine. Its just the 10mm increment that's doing this. Loud whining noise and motor shuddering but gantry not moving. I've tried swapping the driver over but it does the same thing. What gives? Is it likely that my stepper motor just needs replacing??

Maybe your steps per mm for none print movement is set too high in your firmware.
