Hi Tom,
No upgrades to Eqmod or Astroeq. Version 7.4 firmware.
Settings imaged below. The controller did take a fall to the concrete floor and the USB diode no longer works (I found it had fractured when I opened the case) so I think a damaged unit is very likely. I emailed you separately about that with a link to dropbox video before I noticed that you won't have anymore time till October, sorry!
Weirdly, Dec still works perfectly normally but while I have now got RA to slew at full speed (800), before it starts the full speed bit, (during the slow speed start up) it oscillates back and forth and I suspect won't track for the same reason.
I suspected the game pad, too, so all tests since the first event have been with it disconnected.
