The Dec arm position had driven itself all the way against the NEG (North) EOT sensor and seemed to be bound. The commands to slew the travel in the opposite direction did not seem to affect the position. I removed the NEG EOR sensor, and gave the Dec a slew rate command of -10.00 and the DEC arm went back toward the Home sensor and continued to drive until the Dec arm travel hit the POS EOR/EOT sensor. I moved the NEG EOT sensor further in and re-installed the NEG EOR sensor and positioned it so that the NEG/EOR sensor triggers just a couple of seconds before the NEG EOT sensor. I tried The Home command but it did not work and the Dec arm traveled past the Home sensor without stopping. I had to manually slew to Home, and then hit the Home button so that it went to Standby. **NOTE** When trying to find Home from the NEG EOR/EOT status input -10.00 for a Slew rate until the Home GUI illuminates, then stop the slew and put in Standby. When trying to find Home from POS EOR/EOT status input 10.00 for a slew rate until Home GUI illuminates, then stop the slew and put in Standby. ___end___ GENERAL COMMENT BY mcotter: Tue Oct 13 20:19:08 GMT 2020 Kcor running. ___end___ GENERAL COMMENT BY mcotter: Tue Oct 13 21:43:26 GMT 2020 Lots of aerosols visible in the Kcor image, but sky appears clear and blue. Spar appears to be working correctly with no problems apparent. ___end___ GPS COMMENT by MLSO: Tue Oct 13 21:45:09 GMT 2020 Successfully logged in to system Good disk mount GPS software running Last 5 GPS data files are: /mnt/usb/dataoutiq_2020_282_2145.bin 2147483647 /mnt/usb/dataoutiq_2020_283_2145.bin 2147483647 /mnt/usb/dataoutiq_2020_284_2145.bin 2147483647 /mnt/usb/dataoutiq_2020_285_2145.bin 2147483647 /mnt/usb/dataoutiq_2020_286_2145.bin 2147483647 ___end___ GENERAL COMMENT BY mcotter: Tue Oct 13 21:45:22 GMT 2020 Did not run calibration this morning because of time lost working on Spar problem. ___end___ WEATHER COMMENT: mcotter: Tue Oct 13 22:40:50 GMT 2020 Cirrocumulus and Altocumulus clouds forming above and to the upper West of the observatory.
