I wish to see only technical discussion in this topic, though, unfortunately, it didn't happen. Since some incorrect statements were made just above, I must make some clarification. The ShuttleRU_LCD is a different device and doesn't work exactly as a ShuttlePro, though it uses an extended ShuttlePro plugin. I don't know where it came from about exact behavior. There was only one question/requirement from Dave during testing period - changing color of the A-axis. It was a software glitch, not a hardware, and was fixed. I was thankful to Dave for his help with description of his experience and it was really unexpected to see this kind of his reply here.
