Log
1820 - Started setting up the dome
1855 - Started taking calibrations
1940 - Completed calibration
1943 - Waiting for the sun to set
1951 - Mirror doors are not opening
1951 - All 4 mirror doors opened while doing flats and closed properly and while opening it after the calibrations, all four of it is not opening
1956 - While looking at the telescope, we found the motors of the mirror doors to be running even after failing to open the mirror doors
1957 - pinged Ian and vincent on discord and waiting for reply
2015 - Stopped the motor of the mirror doors using a tissue as the motor was getting hot
2016 - Insulating connection between conductors
2016 - Or if it is a distance actuated switch maintaining the distance with that tissue
2019 - For the note we are not physically forcing the motor to stop
2022 - We are assuming that the set screws came loose and the pullet slipped off
2226 - We fixed the pullet by placing the belt back at it
2231 - The belt on the pullet at south side of the mirror doors came out while trying to open and we fixed that as well
2233 - Now everything is looking good but when we click open from the control computer, the mirror doors are not opening
2236 - The motors on the North and South are running but the motor on the east side of the mirror doors feels getting hot
2242 - While trying to close the mirror doors from the control computer, only the motor on the North starts to spin. But when we try to open it up, every motor is running but its unable to lift the mirror doors up for some reason.
2251 - We are waiting for like 10 minutes for the motors to cool down a bit and check if its still not running and looks safe and then we'll start closing down
2315 - Started close down procedure
