Currently Out of Stock at both N.A. dealers. So its a solution I can't obtain, in a useable time frame, anyway. Another thought is what happens to the real time of an encoder edge going by when its subjected to the ethernet packet latencies? I believe some of what I think is bearing noise in my G0704, sounds like a bearing trying to eat its ball cage, is not that, but its partially the noise created by the fast response of the PID causing the motor to slam back and forth in the backlash of the gears. This noise is much worse when the backgear is in high gear, and reduces under loading.
