| - | 5/28/25: Jon replaced the drive belt. Tenatively, this seems to have improved the ' | + | 7/5/25 : See [[sumjulyevent|Report of July 5th, 2025 events resulting in critical failure]] |
| + | |||
| + | 7/3/25 : Got a call from the first shift SSP TA that the shutter error occurred. However, the previous instructions provided where not helping. Upon inspection with the webcam, the shutter was partially opened. Zach took over, parked the dome, and force closed the dome. Once the dome was closed it was recovered. The SSP TA and Zach think the shutter got into this state via a participant quickly / repeatedly clicking on ACP buttons since there was no immediate response from TMO due to the single delay. Zach came up to TMO on 7/3 and visually inspected the shutter, motor, etc and everything looked fine! Zach was also able to open and close the dome several times with no issue. | ||
| + | |||
| + | Note, when Zach rotated the dome a few times, there was creaking noise resembling the first sign of the castor wheels going bad, however, visual inspection shows those wheels are fine. Going to keep monitoring. | ||
| + | |||
| + | 6/28/25 : Upon inspecting the dome / caster wheels - the left most new wheel that we added had the plastic washer shredded in front of it. I do not think this is critical to the function of the castor wheel - but this should be monitored. | ||
| + | |||
| + | 6/28/25 : SSP TA Yujean called Zach at ~2:50pm reporting that SiTech was reading "Bad Scope Connection" | ||
| + | |||
| + | Coming up in person at ~6:30am - Zach was unable to get the camera to stay connected. Restarting the computer would connect it, but then once Zach took a test image the camera (AstroImaging Equipment) would get disconnected. Going up to the telescope, it was apparent that the cords for the camera were dangling (had fallen off their velcro). Zach added more Velcro to the cords and scope to ensure they were firmly attached and not dangling. Camera has now been able to take several test images without disconnecting. | ||
| + | |||
| + | I will assume that the MaxDL run time issue (freezing) earlier in the morning was due to a poor camera connection. After connecting all the cables, ensuring everything is secure, etc - the camera has not disconnected nor has MaxDL frozen. | ||
| + | |||
| + | 6/24/25 : At 12:00am (mid-night) one of the SSP TAs reached out to Zach asking about the weather and noting that TMO was inaccessible. TMO likely lost power due to the storms. Zach was able to remotely restore power by accessing TMO Power 1 and TMO Power 2 - everything was turned off likely to a power event that occurred due to weather. Zach advised the on duty TA not to do observing due to the current and predicted forecasts. | ||
| + | |||
| + | 6/23/25 : Zach checked in at 3am and AAVSO took over. Zach checked in at 6am, despite AAVSO sending a successful run complete log, ACP was prompting a "Motor Stalled" | ||
| + | |||
| + | Jason and Zach were able to get the well back onto the shaft and reattached. Checking the bolt / thread that secures the wheel to the motor shaft should be added to the regular checks. | ||
| + | |||
| + | 6/21/25 : Adam and Zach went up to TMO to manually recover TMO. One of the participants entered the coordinates of their asteroids then used " | ||
| + | |||
| + | 6/21/25 : Zach put the spare timing belt and spare timing pulleys and belt - [[https:// | ||
| + | |||
| + | 6/12/25 : Jon and Zach changed the behavior of the Dome (thru ACP -> Preferences -> Dome Control -> Select Dome). Now the slit will only operate in the parked position. If you attempt to close the dome, it will first slew to part then close. This was done to prevent a potential (albeit low probability) critical failure from occurring due to the discovered behavior of the shutter error in the 100-105 azimuthal range). | ||
| + | |||
| + | 6/10/25 : removed belt wheel on motor (15 teeth) and replaced set screws with actual #8-32 set screws. Not positive about these as they are hard to turn once they go all the way in, but hopefully OK. Pushed that wheel all the way in to better align with worm wheel, now both farther in then they used to be (to try to match set screw hole on worm wheel, but note that set screws on motor wheel are now no longer on flat section of motor shaft, which is less good). | ||
| + | |||
| + | Cleaned the USB connectors for dome and weather station at the Icron in the dome. | ||
| + | |||
| + | 6/9/25 : after report of continued trailing, removed both timing belt wheels. Put wheel on worm further in to try to get set screw to line up with hole on shaft, and attempted to move motor wheel in to match (with some issues due to interfering screw heads). | ||
| + | |||
| + | 6/9/25 : lowered block with shutter limit switches so that they trigger at all azimuths. | ||

| + | 5/28/25: Jon replaced the drive belt. Tenatively, this seems to have improved the ' | ||
