The script in #8 did´t work without the two sleep commands, so its not only shoot that has my problem...
I will see if I can narrow it down somehow.
What are the conditions that have to be met, to make a succesful shoot ?
Flash ready, focus ready etc .
Is it possible to print them in the script to see whats different when the script stops ?

Take a look at the lens functions section at the above link. You may need to wait for get_focus_ok after you do set_focus.

There's also a section in the enhanced photo operations menu called "bracketing in continuous mode." Unfortunately, it doesn't do anything on my sx260 unless I'm in manual focus mode. Unfortunately, what it does in manual focus mode is shut down the camera.

To see what's happening, try adding a print statement right before the sleep in your wait loop. You could try waiting for get_focus_ok instead of get_shooting. There's also a get_flash_ready function. Your wait loop needs to wait for get_flash_ready, get_focus_ok, and get_shooting.

FWIW,  the shoot() command does a half press, waits for the PROPCASE_SHOOTING to indicate the camera is ready, then waits for PROPCASE_IS_FLASH_READY to indicate the flash is ready.  Once that's done,  it does a full press.

@skrylten,

Will you try installing the attached test version of CHDK on your camera and see if the original "shoot" version of your script works?

Will you also install the attached NewClick.lua script and try that? First, it shoots pictures as fast as possible with shoot_full_only. Press <set> to move on to the next test.

The second test is just a loop of shoot calls with no delay. Try that with your flash on and see if it works. Press <menu> to exit the script.

After testing, just install your original version of CHDK again.

Thanks!

@lapser
Installed your testversion, but both my script and NewClick.lua still randomly stops at the shoot command
:(
I have noticed one strange thing :
When the script stops, I interrupt it with a key press. If I start it again, it loops twice for every shoot .
For every stop, it loops one more time, for every shoot.
It doesn´t behave like this, if I interrupt a "running" script.

More testing using this loop that seems to work with flash...
---------------------------------
  for s=1 to n
   press "shoot_half"
   do
      sleep 50
   until get_shooting = 1
   click "shoot_full_only"
   release "shoot_half"
   get_focus f
   get_dof d
   g=f+d*2/3
   set_focus g
   sleep 1500   
   print g,d
   if g>50000 then s=n
   if d<0 then s=n
  next s
----------------------------
I used a "print get_flash_ready,get_shooting,get_focus_ok" between each line to se what happens during the script.
- A print between    click "shoot_full_only" and  release "shoot_half" sometimes crashes the camera
- All 3 parameters are always the same.
- They are 1 after  press "shoot_half" until  sleep 1500, otherwise 0.
- If I replace the sleep 1500 with a wait for get_shooting=0 , the parameters sometimes change from 1 to 0 somewhere between these lines   
   click "shoot_full_only"
   release "shoot_half"
   get_focus f
   get_dof d
   g=f+d*2/3
   set_focus g
as a result the script loops without making a succesful photo.

OK, thanks. I'm re-working the whole thing, so I'll post something when I get it working.

Can you try it with the attached version please.

One thing to keep in mind if you are using flash is that after a few shots the flash recharge time will increase significantly. On my G1X I get about 10-12 shots in quick succession at low flash power then the recharge time goes to about 8 seconds between shots. So it can look like the script has hung in the shoot command; but it may just be waiting for the flash to charge.

I believe there may be one scenario where 'shoot' can hang; but I think it is very rare, although using flash seems to increase the likelihood. The attached version should fix it - if the issue is what I think it is then the script should not hang; but it may skip shots.

Thanks philmoz !

First I will attach the logfiles of what is happening with my two scripts with the old version, before I test your version.

sleep 2000

  print "A",get_shooting,get_flash_ready,get_focus_ok
   shoot
     print "B",get_shooting,get_flash_ready,get_focus_ok
   get_focus f
     print "C",get_shooting,get_flash_ready,get_focus_ok
   get_dof d
     print "D",get_shooting,get_flash_ready,get_focus_ok

Here the script stops, but I think its still running (waiting for some condition in the shoot command ?)
If I interrupt it (pressing the button) and starts it again. It looks the same but only every second loop gives a succesful photo.

Really strange, but this script seems to crash instead of just stop, when I use several print-commands...

@philmoz

I´m impressed ! You are spot on.

I used your version with my first script (with shoot) to make a 276 shot stack (with flash).
It never stopped , but skipped ca 5 shots as you suspected.

Great work !
Whats the solution ?
