I have a Paramount MX+. I regreased it recently and adjusted the plungers. I also had to change the Mount->PC USB cable through the mount.
Now when I guide, I get an oscillating RA trace (see attached screen shot). The oscillations are about once every 3.85 minutes which is about the same period as the worm rotation at 3.875minutes.
I doubt this time period is a co-incidence
I have done the plunger adjustment many times before and it went as per usual, I don’t think they are maladjusted
So, I need to retrain the PEC
I can’t see it being anything to do with cable snag.
If we weren’t having such rubbish weather in the UK I would simply ‘get on” and retrain. But it’s going to be a week or so before I can, so I would be interested to hear any views on my logic (above) and why I would need to retrain after a regrease / plunger adjustment ?
