If it were me, I'd set up one axis at a time and verify that it's working correctly before going any further.

Bob,
I guess its how confident you are in your solution working? ;-)
Its a fairly complex system and you need to identify the root cause of your failure and ensure it is resolved.
Peel the onion.

I don't know about how confident I am about the 'solution working', but I am confident I am removing lots of potential for problems and will end up with a much cleaner install, and a smaller parts count. I will have to hope it's enough.

As I am running the Geko's via motherboard and ribbon cable arrangement I assume it's OK to run the Geko's without motors attached?

Bob,
You might want to check the manual but I believe you can run without a motor. The big issue I think is connecting or disconnecting a motor when powered up.
I like Gerrys suggestion
