Hi James, did you try to run PHD2 guide calibration? That should tell you if the mount is responding to guide commands, and how well.

Hi,

A bit of background first:? ?I have a very old, but faithful, Losmandy G11.? I upgraded to Gemini 2 about a year ago.? Last night I had been successfully autoguiding with PHD2 for a few hours.
?
After midnight I executed a go-to to an object in Cassiopeia.? It was nearly overhead.? The mount head collided with the RA motor!? I have NEVER had this happen in many many years of using my G11.??
?
I decided to re-align and did several go-to's to rebuild the model.? All seemed fine.? Slewing seemed fine.? I started autoguiding with PHD2 and RA guiding immediatley went off the chart.? I checked cabling - OK.? I unplugged and replugged the RA cable - OK.? I slewed the RA several times and it seemed fine.? I started PH2 again and RA guiding went off the chart.? Ugh.?
?
This morning I visually checked the RA motor and housing - it looks ok.? The mounting seems fine and tight.? I have not taken the RA motor off the mount yet.? I have the feeling that since it slews ok, I won't be able to see anything wrong.? I greatly would appreciate any suggestions before pulling the motor off.?

Thanks!
