RE: Spindle Speed with the GS2 Drive

Paul,

Is this true?  The last time I checked, I could not control spindle speed on
the STG spare DAC while using the bridgeporttask, bridgeportio combination.
It did work with minimilltask, minimillio.  Also, how are things coming
along with mapping the motion independant I/O to the STG card.
