Problem with BYE controlling shutter

[AstroImageNut]

When I switch to frame and focus to center an object, sometimes when I switch back to imaging mode BYE will not open the shutter. The system seems  to think all is well and counts down the exposure but the shutter does not open and I can't  abort. I have  to reboot  to make things work again or start Images Plus camera control and take one short exposure, then everything  works again. I'm using a Canon 60Da, any suggestions?

What version of BYE?  Is this s new issue?

Whoops, that probably would have been useful to put in my original post. It is version 3.1.9 running under Windows 10 on a Samsung i5 based 700T tablet. Can't say how new the problem is as I've only used framing and focusing mode a couple of times to frame a target. It has acted up both times, but the problem is not easily repeatable and I haven't detected a pattern yet. If I don't switch to framing mode then the issue never occurs, but it does not occur every time I switch back and forth.

You should install the latest release of BYE (version 3.1.16) and try to recreate your issue. Let us know how it goes.

I would also say that lower end computers like netbooks and tablets can have a problem with USB overload when operating multiple devices like imaging camera and guide camera simultaneously.

Send me the log file the next time it occurs, but astroman is probably right where the USB cable simply becomes overloaded with data and slows down to a crawl.  The Canon SDK requires constant connection to the camera and a non-responsible cable, even for a millisecond, will cause the application to be non-responsive.

I'll send the log files when I manage to get it to lock up again. While it's not impossible that the problem lies in USB bandwidth, there is no problem when guiding and downloading an image at the same time. I would assume that would take much more bandwidth. Also remember that using the task manager to close BYE and then restarting BYE does not solve the issue, although it connects to the camera and framing mode works. I have to reboot or take an exposure using another software package to fix it. Also turning the camera off then on does not help.

I did not mean to suggest that the fact that you are running BYE on a tablet was causing your problem, only that others have had issues when the system is underpowered.

I expect that your issue will be solved by upgrading to 3.1.16.

No problem Rick, it was not taken as a slight in any way. Although not likely, it is worth checking.
