I just wrote you one. One of the things Gpredict can do is control antenna rotators (via the hamlib driver library). In this case, you're the rotator, but hamlib can't handle that (as far as I know), so instead we'll use a program that pretends to be hamlib (more precisely, pretends to be rotctld). Setup instructions (I'm going to assume you're on a unixy ...

I had the same issue. I adjust the Azimuth every day, then sometimes it fails between 15-20 degrees. Then I replaced the regulator with a new one. Now it is ok.

It is unlikely that both op amps have failed, especially since the other half of each op amp drives the meters, which you stated are still working properly. I am initially concerned that you are seeing 5.84 VDC at the rotor. The input to the range pots that are in the rotor should be ~8 volts. This may indicate that you have a wiring error or a high ...

Sorry for the long overdue reply but you didn't tag your response with my ID so I didn't get notification of your response. The control box azimuth reading and the computer azimuth reading share a common 6 volt feed from the rotor potentiometer circuit but each has their own calibration pot. If the control box meter reading is drifting from the computer ...
