i'm at a loss at the mo trying to ge these motors to turn. i have autoconfigured them without the signals hooked in and they were fine , i mean they shuddered slightly for a second or so as per manual . i have mach running with the signals hooked in and the motors can turn by hand when the system is powered up .i power down hook out the signals and power up and the motors come on and are held on. i have gone through the motor tuning and set the appropiate ports and pins and still no joy. i have played with the enable settings and still no joy. there must be something i'm missing. i'm running a demo version of Mach and i'm wondering could this be causing me problems?
