Joakim thanks for your reply.
The one peice of information I forgot to mention. My apologise.
The IBM Machine that the CNC is connected to has an onboard PP which is connected to a 5 Axis breadboard. Typical chinese variety of board from ebay.
It is the type that has the game port for a external controller/pendant.
There is only 1 logitech USB gamepad. I know it's working because i can use it with another joystick plugin. And while using it with the Joypad V2.0 plugin in, only the hard buttons work, not the XY axis of the pots. The pot buttons also work.
Am I missing what you are saying about the mach3 not controlling the drivers, it does control the controller that the drivers are connected to?
Thanks again.
