MDM Trouble Report for 2019 Oct 12

Telescope: 1.3m
Observer(s): Ryan Chornock (Ohio University)
Instrument: Templeton

Problem(s) Encountered:
I was unable to point the telescope to a target near the meridian at Dec=+79. I saw this at positions both east and west and was never near the pointing limit.
The JSkyCalc GUI gave a  slew error  and didn't move the telescope.  I had definitely observed objects at similar declinations (including the same target) with this telescope in the past, so I did some experiments.
I restarted TCS, homed the Dec drive, and checked the Dec controller, but none of those things worked.
As an example: after turning off tracking, the command  point ha=-02:00:00 dec=+73:00:00  would work
 point ha=-02:00:00 dec=+74:00:00  would not work with an  ERROR point illegal Dec 90 
(trying it with dec=+75 would give a similar error, but would say  Dec 91  instead).
I tried creating some fake targets in my target list at various locations in the north and also used the point command, but both failed above dec 74.
We left this unresolved and moved on to other targets.
