A few ideas. Though you are detecting something when a direction key is pressed, can you turn the stepper by hand when the controller is on? It should offer significant resistance, especially if you are trying to turn it by the shaft (does it have a hand wheel?). You can overpower a stepper by hand when powered but it is difficult. No harm will be done, it just trying to make sure it is powered.
If the machine was working prior then change the wiring back to the way it was when operable. There are many settings within Mach or EMC that allow pin assignments and such. We want to minimize any variables if possible.
You mention 4 wires coming from the driver. I am assuming they are coming from the BOB to the driver, not from the driver to the stepper (again assuming the stepper is a 4 wire in this case). One thing I have found is that machine wiring doesnt seem to follow any convention I am familiar with in regards to color. It might from an industrial standard but the typical "black for ground, red for +" is not always the case.
The issue with the flyout is odd. You do have other machines that are CNC correct? And you are familiar with Mach? If not familiar with Mach and you used the flyout, there is a resolution button that only affects that screen, not the direction keys on the keyboard. It has 3 options (maybe 4?) IIRC, they are 1,.1,.01,.001 and .0001. If in one of the finer resolutions, movement would be difficult to detect.
Dont worry about the rats nest during set up. Most of us except those that are very organized go thru this. Probably not the best way, but you wont be the first by any stretch. That being said I wouldnt really be changing anything regarding wiring just yet.
Also I am assuming you have the particular axis "enabled" within Mach. It appears you do from the DRO's and the diagnostics screen.
Finally, Pictures, yes! It does help in identifying steppers, driver chips, BOB's (though you said you are running a C11) and power supplies etc. Simple ones taken with your cell phone and preferably hosted here and not on a secondary site. Ok, that last one might be a personal peave. I just dont want to go to dropbox or any other site to see the pictures of a problem discussed here. I understand many have build logs and posting in both is fine IMO. Others here might need this info in the future. It would be nice if it is self contained.
With a little info and some research on your drivers etc, we should be able to get it running quickly. If you pm me your number as we get further along (assuming you dont get it straightened out prior) I will walk you thru what I know. That should be every bit of a 15 second discussion! ;-)
