Re: More Parallel Port Woe's -- I think?

Mike,

With no step pulses coming to the driver, the motor
should sit still with perhaps a small jitter or whine
as the servo hunts between encoder counts. Is the
motor turning slowly, or is it running flat out? If
running flat out it is most likely that the encoder
signals are phased backwards. If it is turning slowly
it may be that the Gecko is not seeing both of the
encoder phases.

Steve Stallings
