Hi All, I have a 7i92 7i77 combo driving our mill. I flashed it with servo stuff when I installed it. My son and I had been milling parts for a few days. This morning when I booted up I got a strange error and by power cycling the mesa boards, everything came up fine. We were running for a few

Well, when I thought this was going to go smoothly, I've run into mysteries. At my age you'd think I know better than to assume. I was working out the details of the current wiring to the Anilam. First surprise, there is no motor tach to the servo amplifiers. They use none of the PID
