I have not had a counting issue for a long time now. The second to the last firmware update for the ASC1 corrected a counting issue that some folks had including me. The AJAK could be a little noisy for my high resolution sensors, but locating the sensor wires away from the motor really helped this problem. I'm running a high resolution sensor of mine in a VonWeise actuator with an ASC1 controlling it for several months now and not one missed count or other issue to report.How is the noise now? Are you getting any missed counts because of the noise?
