DuetLapse available for Alpha testing
-
@PaulHew You can add the -q 25 (or whatever you wish to try), just put it before the -o. Or, more correctly, not between the -o and the filename.
At this moment, none of my Pi cameras can reach to see a printer. Ribbon too short. I have some longer ribbon, and an Arducam, on the way. Amazon keeps moving the date (which I totally understand). I'll be able to fine tune this more when I receive that stuff.
Meanwhile, keep the specifics coming! (And, you are a lot more of a Guru than you think)

Just about to try it but noticed that it seems to be opening and closing the unix socket twice a second. Not usually an issue except I run the DCS with debug logging so it's kinda distracting. Any chance of just keeping the socket open or better yet, just getting the model updates as they happen?

Any ideas?

Which USB camera?

It doesn't touch the unix socket. It is opening and closing a websocket connection, and not persisting it. This was a design choice in startup to not track state. I will look into persisting that connection.

Keep the ideas coming!
Danal, here is an idea, not necessary specific for this timelapse app, but since you know how to monitor the duet during printing and generate visualization, would be interesting to have something that plot the different time left estimations that the Duet provides.
Think of an x/y graph. X is print time from 0 to total print time T. Y is the time left for completion. The ideal reporting is a straight line from (0,T) to (T,0). And then you can sample the duet and plot the time left graphs by the various methods the Duet uses.
The output can be an actual graph or a csv file that can be plotted with a spreadsheet and the likes.

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?

Ah yeah, the websocket will result in the same messages. It's not critical so don't spend all that much time on it.

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.

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 -
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 -

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!

CheersI 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.

Excellent point.

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

THANK YOU
I will update

Another tip if you want to play around with DuetLapse without having to set a print going.
Temporarily changeif ('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?
