Our controller is an acramatic 950. We went through the toolbox diagnostics and found an issue with the B-axis resolver in the history. We went ahead and replaced the B-axis motor but it did not help. We have also replaced a cpu/gram board and the RIPT board. We still have the "not enough good boards" and there doesn't appear to be any faults on any of the other boards. The power supplies check good with minimal noise. There is a loop back plug available for testing but we don't have one. So far MAG hasn't been much help.
