This might be true with parallel port software stepping systems that require a high speed base thread for pulse generation and perhaps encoder counting, but is not the case at all for servo thread only systems, that is systems that have hardware step generation and encoder counting or Ethercat based systems where all the high speed logic is on the drive. Almost any current motherboard will work with acceptable latency for a servo thread only system. With the right I/O hardware and tuning, 100s of usec of jitter can be tolerated meaning its difficult to find a motherboard that does not work Peter Wallace Mesa Electronics ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
