Thor, or should that be Zeus?

you just need to have an RS232 connection to use the servo software, without Rs232, you will need to get a USB to RS232 adaptor.
I have never used the interface on the driver to do any tuning, because it is so much easier using the software.
Tuning with no load is not right and may cause the controller tuning to fail, or make the axis very spongy, so make sure you have the mass of the table there while tuning.
Also make sure you save it after, or you will delete the tuning, once you cycle the power.

Hi Gary, would a USB to RS232 interface not suffer the same issues as standard USB when it comes to timing's? Or is there something I am missing here.

I also wonder if Linux is more reliable than windows (Especially when using USB) especially a Linuxcnc Live cd? I have no idea if you can get Mach 3 for Linux.

Chaz I'll be interested to see if it was a crossed cable causing your issues, fingers crossed for your weekend movements ;)
