DuetLapse3

stuartofmt

This is a modified version of the original DuetLapse created by Danal Estes.
We should all remember him for his generous work

General Description

DuetLapse3 provides a highly configurable program for creating timelapse videos from printers using the Deut3D software.
It can be run as a one-of or continuously in the background.

A companion program startDuetLapse 3 provides administration capabilities and is especially useful if multiple instances of DuetLapse3 are running and connected to multiple printers.

Details of DuetLapse3 are in this document:

DuetLapse3.md

In addition to a browser interface DuetLapse3 can be controlled directly from gcode.

Controlling with gcode.md

Details of startDuetLapse3 are in this document:

startDuetLapse3.md

Useage examples are in this document:

DuetLapse3 Useage Examples.md

Version - 4.0.0

[1] Added the ability to control the program with gcode M117 messages
[2] Added the ability to execute an arbitrary program by sending M117 gcode with configurable prefix
[3] Added -restart option to allow a program to continue running at end of print
[4] Significantly improved ability to continue running after extended network interruptions.
[5] Can continue to run even if printer is turned off
[6] Changed - extratime handling so as not to require tpad support in ffmpeg
[7] Added -minvideo option to set minimum video length (seconds default 5)
[8] Changed default -poll to minimum of 12 seconds.
[9] Changed default -seconds to minimum of 12 seconds.
[10] Suppressed a lot of output unless -verbose is used
[11] Changed logfile naming convention to better support - restart.
Initially the logfile is created with a timestamp. When the print starts the logfile is renamed to reflect the name of the print job

Version 4.1.0

[1] Added support for M117 DuetLapse.change.movehead=x,y
[2] Added Delete, Zip, Video in UI for completed jobs in currently running instance
[3] Suppressed long message when a client (browser) disconnects during UI update

The readme.md file contains the full version history

Please post suggestions for improvement in this forum, not in the github. That way we get the wider, interested audience.

@stuartofmt Excellent way to carry on Danal's work!

@stuartofmt I am running the LPC SBC Port of RRF. But i can not connect to my Pi.
here is my Object Model
alt text

192.168.140.126
192.168.140.126 The printer at 192.168.140.126 did not respond
192.168.140.126 Check the ip address or logical printer name is correct
192.168.140.126 Duet software version must be at RRF3 or above and suppotr rr_model

Best

@stuartofmt
The duet+SBC doesn't support the object model and uses machine/status instead.
The DuetWebAPI handled both methods of obtaining information.

stuartofmt

@PCR

Instructions on wget for download fixed. Thanks!

stuartofmt

@jay_s_uk

Let me take a look at the SBC situation (which I do not own). I was under the impression that /machine/status was replaced (to be?) by rr_model as the preferred method.

It may take me a few of days to figure out.

jay_s_uk

@stuartofmt its the other way round.
rr_model is replaced by machine/status in SBC situations

stuartofmt

@jay_s_uk

OK - thx. It's not difficult but I will need some help testing.

jay_s_uk

@stuartofmt
i can provide a current 3.2 output from machine/status if needed.
i'm sure @PCR would do some testing for you

stuartofmt

@jay_s_uk

That would be very helpful (much better than closing my eyes and imagining) - thanks!

Could someone please try this? It's a test script for the SBC calls. It's read only with the exception of a M117 'Test of SBC' which should show up in DWC.

Once its placed in a directory permissions will need to be changed.

chmod +x ./SBCTEST.py

it can then be run with the following command

python3 ./SBCTEST.py -duet <ipaddress of your SBC printer>

with a bit of luck it will report success, in any case - if the resultant SBCTEST.log file can be posted back, that would be a great help.

I've tested it on my non SBC duet - there may be some syntax errors in the unexercised code - but I hope not
If there are then a screen shot would be helpful.

Can do it tomorrow! Thank you

@PCR @jay_s_uk

Thanks - there was a silly formatting error (now fixed) but underlying that it looks like there was an http 405 error returned.

I've added a two more version of the send gcode function to try - hopefully one of them works. Unfortunately the documentation and other examples (which purport to work) are somewhat vague on this aspect ....

ALSO - if you are running RRF3.2 the default behavior for CORS seems to have changed. With another program I am using (DueUI) - I had to add the following to config.sys (up front in the network section) - after the upgrade. BUT DuetLapse was unaffected. It MAY be different on SBC.

I'd suggest first trying "as is" but if this script still does not work with one of the methods (depending on what the errors are) - the CORS thing may need to be looked into.

M586 C"*"                                     ;enable CORS

New Test Script is here

fractalengineer

Awesome Stuart, thanks for carrying on Danal's work

Looks well documented too, I'll give it a shot over the weekend.

Very neat of you to handle issues outside of your own setup too

Do you think in it's current state this could realistically be implemented as a plugin in DWC for a possible GUI?

stuartofmt

@fractalengineer

Thanks. As a plugin ? hmmm . I'll have to see what that means / entails. Let me put that as a priority 2 for right now.

Priority 1 is getting SSB working and tidying up some of the logic / behavior surrounding pauses. I did not test that aspect much and its somewhat ambiguous - so stay tuned ...

OK! Looks like V1 worked!! So you should have got a message on DWC saying "Test of SBC"

Did you see that ?

jay_s_uk

@stuartofmt
No, nothing displayed on DWC

stuartofmt

@jay_s_uk

Ok - I'm going to have to get some help. The code I have seen elsewhere (including Danal's) does not work (or I've done something stupid). The one that reports success - does not seem to send the gcode .... go figure .....

So - this should work for SBC -- but not for using the pause capability (that's the only thing that sends gcodes). ~~Appreciate it if you could test before I update github~~

Hmm - wont let me upload the file to here. I'll update on github - if you would not mind downloading from there.
