2023-07-27 to 2023-08-24: Tip Tilt Stage X Axis Crippled

Starting on the night of July 27 (HST) the tip tilt stage has had problems with the X axis. This has resulted in poor tip tilt performance. As of Aug 14, troubleshooting is ongoing.

Some range was recovered by chance while troubleshooting on 2023-08-24, so the night of 2023-08-25 looked like it had reasonable tip tilt performance. The stage health seems variable, so we are still working on troubleshooting.

Update on 2023-09-04: the tip tilt stage range has been sufficient for reasonable performance since the night of August 25. This may still change, but we are performing satisfactorily for now.
