Failed to set the EFW the Autorun stopped

NoMiSkies

Last evening when I tried to start an Autorun sequence in ASIAIR I got the message "Failed to set the EFW the Autorun stopped".

Earlier that evening I removed my ASI533McPro to clean its sensor lens. As I screwed this back into place I noticed that the filter was a little out of place but other than that nothing seemed out of the ordinary. I moved the filter slightly and screwed the camera back into the filter wheel.

Everything seemed to work fine with last nights setup until I attempted to capture the Autorun sequence. That is when I repeatedly got the above message.

Today I looked at this in my house. I could hear an audible hum when I switched filters inside of the filter drop down, but when I get out of the filter tab the filter number always shows up as 1.

Just as in last evening I am getting the message "Failed to set the EFW the Autorun stopped".

I took everything apart but couldn't see any visible issue with the filter drawers.

Please help me to identify the issue so I can get back up and running again.

NoMiSkies You need to see what is happening inside the EFW.
Take the EFW off your optical train then try too move manually the filter; check for any resistance signs. If you can move it then connect it to AA. Try to change filters from the app and check if the filter wheel rotates.
If the filter does not rotate you will have to open the EFW then try to see if the motor shaft is not slipping on the edge of the filter wheel.
If the shaft is not slipping and not rotating and there are no signs of resistance then your EFW motor might be toast and you will have to get another EFW.

Thank you for the ideas.

I did take my filter wheel apart and looked it over again.

I noticed that the central screw was quite tight so I loosened it up.

I was quite happy to see that this apparently has fixed my problem.
