Sequence acquisition fails when camera exposure long enough to return a single image per second

[Ion-e]

With the shown parameters in the image. (Acquired item is number 10 on the image)

This issue is to figure out why it has failed, and whether it's an issue or not.

However, without a procedure reproduce it, I'd suggest closing it. It is covered under other issues already, like these and some other internal issues.

• Add mechanism for low level to report more informative errors #106
• Improve error detection during synchronized acquisition #54

This bug is a bit of a mess.

The original issue was triggered with the following parameters:

However there seems to be a different issue whilst doing an acquisition with the following parameters:

I have managed to reproduce the latest one, do you want me to close this ticket and create 2 new tickets for them? @cmeyer

[Ion-e]

Verified as persisting. @cmeyer, the error now looks more detailed, do you think we should still close the issue?

@Ion-e can you check with @Brow71189 or @bentps whether we're trying to do something non-sensicle here!

Fresh launch of Swift, run scan briefly, stop it, then use these parameters and it seems to work for me with latest version. So I can't reproduce this issue without further info.

[Ion-e]

Confirmed this happens consistently.

[jamesrussell216]

Happens for me too. @cmeyer try it with "Spectra" selected instead of "Image"...

Aclaration, there seems to be a few different errors here and last few comments only addresses the last issue.

Other potential issues still pending of repro and validation.

[cmeyer]

If there are other issues, can you file them individually in new issues and close this one?

[Ion-e]

Both issues confirmed as fixed.

Thanks!
