MDM Trouble Report for 2013 Feb 04

Telescope: 1.3m
Observer(s): Kay & Moran (Columbia)
Instrument: templeton direct

Problem(s) Encountered:
Large slews to objects worked, and the object appears at top
corner of image. But attempts to center on the object were not 
successful: using the offset button on the GUI, making slight
adjustments in the 'new RA' and 'Dec' boxes on the GUI, and
using the command line ('offset' or 'point') either did not
move the telescope at all or moved it in unexpected directions
and/or amounts. In these cases, the TCS control panel indicated
the coordinates had changed after the attempted move, but the
image showed that no change (or a change different than the
one we wanted) had occurred. We also had intermittent 'point
not converging' errors with some large and small movements.
These would leave us somewhere on the way to the next position,
so we would toggle the tracking, return to the zenith, attempt
the move again, and it often then worked.  Finally, at least
once, a command-line 'point' command was made, but the telescope
didn't move and and the status line showed instead a response
to a 'where' command ('where' had been the previous command and
had executed successfully).

We checked and zeroed the tilt meters, refreshed and restarted
the TCS GUI, and restarted the telescope `services' on McGraw -
none of which had an effect.  We did not attempt to reboot
McGraw.
