    hm and just in case wget messed something up .. git clone of both repos

    root@octopi:~/DuetLapse/DuetLapse# PYTHONPATH=/root/DuetLapse/DuetWebAPI python3 DuetLapse.py -h
    Traceback (most recent call last):
    File "DuetLapse.py", line 21, in <module>
    import DuetWebAPI as DWA
    File "/root/DuetLapse/DuetWebAPI/DuetWebAPI.py", line 27
    URL=(f'{self._base_url}'+'/rr_status?type=1')
    ^
    SyntaxError: invalid syntax
    root@octopi:~/DuetLapse/DuetLapse#

    I don't get it, I don't see that this line changed since forever?!

    looks like F-Strings are in from 3.6 only raspbian on pi3b+ latest comes with 3.5.3 😞

      @arhi said in DuetLapse available for Alpha testing:

      URL=(f'{self._base_url}'+'/rr_status?type=1')

      @arhi Very interesting, I don't get that, and that line is not a syntax error. Hmmm... Let me think of a way to pin this down.

        F-strings are 3.6 python from what I read online, and stretch has max python 3.5.3 ... I'm now going to move to buster and see if it uses newer python

          Excellent detective work. I had no idea f was that recent.

              apt-get install libatlas-base-dev

              solved the numpy error

                one hint, I don't know python but might be cool to add argument to DuetLapse to point to DuetWebAPI library?

                I added directly to code

                 except ImportError:
                

                but would be cool to read that from the argument line 🙂 so we can normally git pull changes and not need to copy stuff over each other 😄 especially as python is ignoring symlinks

                      @Danal I don't know python so this should probbly be done better by somehow defining parameter to onePhoto() not mandatory, or if there's already a global with this info but this works awesome for me so if you like you integrate 😄

                        Python honors symlinks, that is exactly how I'm keeping one central copy of DuetWebAPI and not copying it around to each DuetLapse, TAMV, etc, etc. as I develop this stuff. If you want it not in the current directory, and/or don't want to use symlinks, then properly put it in Python's path please.

                        By the way, git clone will NOT update things, 'wget' has all kinds of edge cases, I haven't found a really bullet proof way to distribute scripts from github (besides set up a package server. Which I am reluctant to do, and even that requires entries in /etc directories on user endpoints).

                        Anyway, symlinks work fine, I'm curious why yours don't.

                        ln -s ../DuetWebAPI/DuetWebAPI.py DuetWebAPI.py right?

                          kill me if I know why but it didn't work .. I'll try again later but this work as is now so ...

                          and/or don't want to use symlinks, then properly put it in Python's path please.

                          Need to try that again, when I did with PYTHONPATH=/root/DuetLapse/DuetWebAPI python3 DuetLapse.py it was finding api ok but failed something else, but maybe now that I fixed the other thing that will work, will try 🙂

                          By the way, git clone will NOT update things

                          of course, git pull does ( git checkout or stash first if files are modified 😄 like they are now)

                          'wget' has all kinds of edge cases, I haven't found a really bullet proof way to distribute scripts from github (besides set up a package server. Which I am reluctant to do, and even that requires entries in /etc directories on user endpoints).

                          git clone
                          git pull
                          git checkout/stash

                          works awesome, the only issue I need to handle is this path for libs so it knows how to find api, will retest this but even as is it's not a biggy

                          hahaha retested the symthing now, it works, the %^$#*&^#

                          PYTHONPATH=/root/DuetLapse/DuetWebAPI python3 DuetLapse.py -h works too, I'll use this way .. the problem was obviously the numpy or whatever is that thing called...

                          anyhow, these are irrelevant parts of that diff 🙂 .. what about that change in the onePhoto() ? makes sense?

                              Makes perfect sense, I just need time to look at it... probably next day or two.

                                  Great program, but I still have not got it quite right. I am currently using. /DuetLapse - duet 192.168.1.16 -camera pi -detect pause, with M25 and M400 added to each layer in gcode (easy to do in kisslicer). The problem is that two frames are taken, one when the head is moved away by pause.g, the second a bit later, when the print has resumed. I also get an error message on the console 'm24: cannot print because no file is selected'. It looks as though the m24 is being sent twice.
                                  I have edited my pause.g so that there is no z shift.

                                  Just pushed changes to the detect pause logic that should eliminate this. It has been tested to ensure no syntax errors, but has not been run through a print.

                                    @Danal here is my first go

                                    https://vimeo.com/415969620
                                    Worked fine with M226 in the gcode file. Excellent. Will try detecting layer changes later. Great work.

                                      I was attempting to run this on the same PI as my OctoPrint setup. I kept getting errors saying numpy wasn't installed. After attempting the suggested command to get numpy installed, it claimed that pip wasn't installed for python3. After a lot of googling I got pip and numpy installed, but I was still getting the same error saying numpy was required.

                                      I finally added some additional output to DuetLapse.py file and found that I was getting the following error:
                                      Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory
                                      It looks like the answer to that error was to run
                                      sudo apt-get install libatlas-base-dev

                                      I just thought I would post this here in case anyone else runs into this issue, or if anyone has a better way to solve it. I am novice with Linux and Python, so this may not be the best way to handle things. 🙂

                                      I am using the following versions of OctoPrint/OctoPi:
                                      OctoPrint version: 1.4.0
                                      OctoPi version: 0.17.0

                                        Interesting.

                                        I developed the script on the "Duet" provided image for a Pi, and I'm sure that has things installed that were transparent to me. I've tried to have the script produce meaningful errors when something is missing, and I will need to do that for Numpy. Also, I will look into the libatals-base-dev.

                                        pip is not needed by the script at runtime; it is needed to install things the script needs. As you say, python3 does not install pip by default.

                                        A lot of instructions show how to "bootstrap" pip install via python itself. The actual proper way to install pip on a Python3 (or mixed) system is sudo apt install python-pip. This would (should?) get the libatlas dependence automatically.

                                        I've updated the script to show the required commands, if numpy is not found.

                                        Thank you.

                                          I am pretty sure that is not how I did it 😞 . Good to know. Thanks for looking into that. Hopefully it will help others in the future.

                                          I would also like to mention that it is working now, happily taking pictures of my current print. 🙂 Good work. I appreciate it.
