DuetLapse available for Alpha testing
-
Thanks!
Also.. If you pulled the script from github after Sat Apr 25 21:27:50 CDT, it no longer looks at Z. It looks at layers. Which works MUCH better.
-
Aha!
M25 is not for pausing from within a file being printed. Please change these to M226.
-
@Danal thanks very much - will give it a go.
-
Still getting the same behaviour with M226 in the gcode, with or without z move, using freshly pulled scripts.
-
Thanks for checking that, I will give this a look.

If you are using the raspberry pi camera, note that it has a default 5 second timeout. If you include -t 1 in the camera parameters, it works much more quickly. I have also started including -ex sports, which uses a fast shutter speed, and -mm matrix, which seems to give a better exposure; -n gives nopreview.
With the faster response, I now sometimes get more than one extra picture per layer - I got 547 for a 0.2 layer benchy, instead of 240. -

Is an effort with pla. Used detect - pause, with M226 in the gcode at each layer change. The extra frames have to be deleted before running ffmpeg again -
some, not so recent, rpi installation ...

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 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.

@Danal I don't use python at all so I don't have anything but what's normally there with the distro... so, troubles with buster too it comes with newer python but again

I love how consistent APT system is

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

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

this last part was on me - works ok now

@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.
