I'm the dope who originally posted this on CN :). I wasn't specifically posting it as a problem. It was more like a "hey cool, this mount can track for 10 minutes at 2800mm without guiding!", and "here's what I did" post. I loaded more counterweights than the specs of the mount originally so I didn't think there was anything to fix.
I do now...
It seems that there is a some positions that if I slew my mount there, it goes into an infinite "oscillation" mode. I can physically see the scope move back-and-forth a few millimeters about once a second, and it will keep doing that even if I stop tracking completely. It stops though if I park the mount in that position.
I'm running directly through the ASCOM driver v5.30.10 connecting via USB. (I'm still learning APCC).
The mount firmware is VCP5-P02-08. The encoder firmware is A02-08.
