Canon 600D T3i "Failed to expose" error

I checked, and the verbose was checked. I did another try with the canon driver as Jassem did, but again the same results. Also, I attached a picture of my camera configuration screen that I currently use. Maybe it is one of the camera settings.

Do you know what event the ekos driver was waiting for before it shows "failed to expose"?

Thank you rdricks. I think the driver configuration was the issue. I was able to take 30 shots 300 seconds each in one session without a single error. Here is what I've done and configured (for future reference of similar problems)

1. Upgraded my camera firmware from 1.0.2 to 1.0.3 from Canon website
2. Used the Canon DSLR driver
3. Main control -> Mirror lock = 1 sec
4. Options -> Force bulb = OFF
5. Image settings:
- Image format = RAW
- Transfer format = NATIVE
- Capture target = SD CARD
- SD Image = DELETE


As I changed many parameters, I really don't know which one was essential to fix the problem, but I'm glad it worked.

One last thing, when I configure the driver and press save for the configuration, it gives me a message that it saved, but when I reopen ekos/indi again, I only see the defaults. Is there is a way to keep my settings?


Thank you

I’m glad you got it working. It can be finicky, but once it is going it is worth it.

On the older version I never did get it to save those settings. I needed to go in each session and make sure they were set appropriately.
