      Would it be possible to use an old iphone as the camera?

        I noticed that if you have a password set (M551 P"Password") then DuetLapse can't connect to the Duet.

        Attempting to connect to printer at 192.168.1.104
        http://192.168.1.104  does not appear to be a RRF2 or RRF3 printer
        Device at 192.168.1.104 either did not respond or is not a Duet V2 or V3 printer.
        
        

        Do you have any plans to add this feature in the future?
        Cheers

          Teslong USB "Endoscope". It only supports MJPEG as a palette and I just noticed that you've got YUYV hard coded on the fswebcam command line. Maybe don't specify '-p' and let it default?

          I think I did that and it required it for some reason. I will try a couple of different things to get it as automatic as possible.

          fswebcam doesn't require it at least for my camera. It figured out MJPEG by itself. Maybe it's an issue if the camera supports more than 1 palette. You could check for the existence of ~/.fswebcam and if it's there, add a -c ~/.fswebcam to the options. This way a user can put whatever options they want in it.

          Once I changed the palette, it worked great!

            Thanks for sharing I. I'll try installing this in whilst in lockdown.
            I had an idea to use a pi remotely to control RGB LEDs based on the printer status. (eg red = heating, white = printing, green = finished)
            I might try and learn how to do this based on your code/logic

            The "interface" is in a separate library, for just that reason.

              I didn't but based on your feedback, I will look into it.

                Yes, if it runs software that will allow a still image to be retrieved via a know URL.

                  HA! Just discovered another reason to use a config file if it exists... To turn off things like auto-focus. 🙂

                      Found a solution to an issue I was having using DuetLapse with MotionEye.

                      I have a raspicam which is connected to a Pi3B running Motioneye.

                      MotionEye will allow a single image to retrieved at a URL similar to:

                      http://192.168.1.106:8765/picture/1/current/?_username=admin&_signature=b75e2c8efb0c0694a7a4ac1f48037f90566fbead
                      

                      Using this URL with DuetLapse gives this error every time it tries to get an image

                      Capturing frame     0 at X65.74 Y47.41 Z0.30
                      http://192.168.1.106:8765/picture/1/current/?_username=admin:
                      2020-04-07 15:10:57 ERROR 403: Forbidden.
                      

                      So I amended the following line in the onePhoto() function in DuetLapse.py

                      cmd = 'wget --auth-no-challenge -nv -O '+fn+' '+weburl
                      

                      to

                      cmd = 'wget --auth-no-challenge -nv -O '+fn+' "'+weburl+'"'
                      

                      to put quotes around the url. This seems to fix the problem 🙂

                          Another tip if you want to play around with DuetLapse without having to set a print going.
                          Temporarily change

                                  if ('processing' in status):
                          

                          to

                          #if ('processing' in status):
                          if ('M' in status):   # detect simulating instead of processing
                          

                          This will make DuetLapse think the Duet is printing when it is simulating. Remember to change it back later 😉

                          Maybe a -dry-run option can be added to do this in future?

                            I've just been starting a print, and then pause/canceling it.

                            Of course, it can do whatever we all agree to... and can code... and dry run is dead simple. I would note that it really only applies to -seconds. A dry run with any kind of -detect is never going to detect anything.

                              It detects layer changes when running a simulation but, as you say, since nothing is physically moving the video is going to be a bit boring. Useful if you are testing options or trying simple code changes though. I know squat about python so I need all the help I can get. I do find your code very easy to follow though 🙂

                                Thank you. I try to balance being "python-esq" with being readable. For me if nought else.

                                How about having the "detect printing" detect BOTH processing and simulation? Since we control if the script is running, I see very little downside to this.

                                    Keep the ideas coming!

                                    In my customised build of Raspbian with duetpi I created a timelapse.desktop entry so that I can access your program from my start menu.

                                    By default I set it to take a picture upon Z movement.
                                    So now, when I start a print and the printer is ready all I have to do is click on the program entry in the start menu.

                                    timelapse.jpg

                                    Thank you again danal for giving us this great program.

                                      I've set it up and it works 🙂
                                      I did get an error on a small print doing a quick test though
                                      The error was "requests.exceptions.ConnectionError:

                                      ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))"

                                      My guess (Although I'm not a Python expert) is that the pi couldn't keep up saving the images as the layers were only taking 20sec (And its an old V2 pi)

                                        I actually think it might be my Duet wifi board causing an error. I've also got a duet maestro and running the same python settings on the maestro IP address hasn't resulted in the "('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))" error

                                          Updates based on feedback:

                                          • Added -dontwait flag. This causes the script to not wait for a print to start; it captures images immediately. Of course, it will only capture things that happen... Example: If told only to capture on layer changes, well, that won't happen prior to a print...

                                          • Added 'camparms -parms' subsection to command line flags. Anything in that subsection is passed to the camera command (whichever for the appropriate camera type, fswebcam, raspistill, or wget)

                                          • Removed pallet from fswebcam (USB attached cameras, despite its name). It will automatically attempt to find the best, or you can specify one, example:
                                            ./DuetLapse.py -duet 192.168.7.101 -dontwait -seconds 3 camparms -parms -p YUYV

                                          • Removed -q from fswebcam. Default is 35. You can override, same as above.

                                          • Slightly changed the loop timer, to beat on the printer a little less often.

                                          *** IMPORTANT *** Found a bug in DuetWebAPI and fixed it, you must download this as well. Therefore, pull these two things into the same directory. One way to do this would be:

                                          wget https://raw.githubusercontent.com/DanalEstes/DuetLapse/master/DuetLapse.py
                                          chmod 744 DuetLapse.py
                                          wget https://raw.githubusercontent.com/DanalEstes/DuetWebAPI/master/DuetWebAPI.py
