I have bought a Shuttle Express and cannot get it to operate under Mach3. I have configured it using the add on config plug in and it is enabled. In the config set up the buttons have been set as X, Y, Z, A, and step and the setup selected as Express. I have then selected the MPG on the shuttle/jog window and selected CAL. This is where it starts to go wrong I think as the three steps for calibration do not recognise the shuttle movement and nothing is calculated. Windows XP has recognised the USB shuttle plugged in and reports it as available. Non of the buttons seem to select anything and the inner detente wheel and outer sprung wheel do nothing. The LED against the MPG continuously flashes. changing the Mode has no affect.
Offers of help on what to do would be appreciated please.
