MDM Trouble Report for 2018 Oct 31

Telescope: 1.3m
Observer(s): Weil & Podjed (Dartmouth)
Instrument: Echelle

Problem(s) Encountered:
We encountered multiple problems at the beginning of the night regarding
pointing and data acquisition. 

First, when we attempted to slew to a new target, the telescope
repeatedly came back with a slew error. The error read:

ERROR point not converging dist=11.430 dra=8.641 ddec=7.483

(although the numbers at the end changed slightly each time.) 
After driving the telescope by hand toward the
zenith and then slewing the telescope again, the telescope pointed
without a slew error. The error repeated itself again 2 slews
later, but was fixed by just telling the telescope to slew again. 

At the end of the night we encountered more pointing errors with the
error code: 
ERROR dome axis=m_az timeout

This time we managed to get the telescope to point the zenith without
a problem, but then when we attempted to point to a target again, the
telescope continued not the slew. We opted to the close the telescope
at this point.

In addition to the slew errors at the beginning of the night, OWL also 
stopped taking data. We attempted to restart OWL and got the 
following error:
ERROR - Driver  PCI Device 0  failed to open
ERROR - ( CArcPCI::Open() ): Failed to open device ( /dev/astropci0 ) : ( errno: 16 ) - Device or resource busy

Problem was fixed when Eric rebooted mdmarc2.
