Canon 600D T3i "Failed to expose" error

Hello

I ran into a problem yesterday which is my Canon 600D was failing periodically every other image to capture images with the error message "Failed to expose". I found that this only happens with long exposures (300 seconds) but not for the sort 30 seconds ones...

I tried to enable the debug log, but as soon as I enable it and connect to the driver, it automatically switches to Debug disabled, so I only have the regular verbose output as attached. I looked into the forums, but the only related problem was due to a new build and noise reduction function that I don't have.

Any help would be appreciated...

Thank you
Mohamed

I use a Canon 600D (T3i) and hove not experienced this, but it may be a new bug.
The logging settings in the INDI control panel are overridden by the global log settings in EKOS. From the Setup tab of EKOS, click on Logs, and enable logging for INDI, Capture, and CCD.

Hi Ihoujin

Thank you for your reply. I was able to create the log file with all details including driver debugging, and emulate the problem... PFA and let me know what do you think.

PS: my camera firmware is 1.0.2

thank you
Mohamed

I recommend you switch to the GPhoto driver.
Edit: Also Camera needs to be in Bulb mode for longer exposures.

Thanks, but how I can switch the driver? I choose Canon DSLR from the drop-down list as my CCD camera in ekos configuration.

Bulb mode: I always use bulb mode


Thank you

Instead of Canon DSLR, Choose GPhoto for your 'CCD' in the Profile Editor.

Hello Ihoujin

Thank you for your reply. I did try the GPhoto driver. It worked well for the 1st 300-sec picture but it gave the same error on the 2nd capture.

Attached is the log file for the GPhoto and screenshot for my configuration.

Any idea what went wrong here?

I couldn't reproduce your experience on my end. And your log doesn't contain much information. Have you set it to verbose logging?

I just tested on 600D with > 300s exposures and they worked fine without any issues on the latest sources.

GM Jassem, which driver did you use? The Canon DSLR or GPhoto?

Also how I can check if I have the latest ekos/indi versions?


Thank you

Canon driver. I don't think it has to do with driver changes though.. there is another factor here.

Last year I had similar issues with a Canon 1Dx. I systematically tried changing settings, and my final settings are below. This was an earlier version of SM, but it is worth a try. Note that for the capture target I had SD card, the had Delete SD image checked. I still had the imaging sequence set to save to StellarMate, so no images were actually lost.

I used these settings successfully for several months until I switched to a Cooled CMOS camera.

Main Control:
Mirror Lockup = 0 (It I set the mirror lockup on it would fail, and I would need to reboot the system and restart KStars on the Mac)

Options:
Force Bulb = OFF (Camera was set to Bulb mode, if I used Force Bulb it would fail)

Image Settings:
Capture Format = RAW
Transfer Format - Native
Capture Target = SD Card (I think this one was the key in the Image Settings tab)
SD Image = Delete
