Hi all,
I'm having a peculiar issue with slewing taking forever on SGP sequences. Here's a typical run:
- SGP starts normally, M-uno slews normally first target starts normally.
- At some point, one of the targets takes forever to slew to. It's not 100% consistent, sometimes it can be the middle one sometimes the last one.
- SGP log doesn't show anything unusual, except for the zillion "Telescope is reporting slewing" messages. Example below:

- This process takes many hours, but apparently it reaches target at some point:
[02/17/23 04:30:41.809][DEBUG][Telescope Thread][SQ;CE;] Telescope: Observatory is reporting slewing
[02/17/23 04:30:43.018][DEBUG][Telescope Thread][SQ;CE;] Telescope: Observatory is reporting slewing

[02/17/23 04:30:46.242][DEBUG][Telescope Thread][SQ;CE;] Telescope: Settling has completed
- It plate solves nicely, but this specific target was at it's time limit by then, so the sequence continued to next target:
[02/17/23 04:36:02.873][DEBUG][Sequence Thread][SQ;] Scope reports it is done with synchronous slew, verifying...
[02/17/23 04:36:02.874][DEBUG][Sequence Thread][SQ;] Telescope: Observatory is reporting slewing

...

[02/17/23 04:37:18.984][DEBUG][Sequence Thread][SQ;] Telescope: Settling has completed
- And it continues normally.
SGP people say the driver is reporting the slew to SGP, so this isn't anything they can sort. The fact is that this happen every night, and it's getting really frustrating. Has anyone seen anything similar?
