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.

It is also available as an SBC plugin.

A companion program startDuetLapse 3 provides administration capabilities and is especially useful if multiple instances of DuetLapse3 are running and connected to multiple printers. This is largely redundant due to continuous improvements in the DuetLapse3 UI and the ability to control DuetLapse3 with gcode instructions.

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

Useage examples are in this document:

DuetLapse3 Useage Examples.md

Version 5.0.0

[1] Completely revised UI
[2] Added display of last captured image to UI
[3] Added ability to specify a config file with -file option This avoids the need for long command lines. Options in command line over-write those in config file
[4] Added -maxvideo. Limits the maximum length of video by varying fps as needed
[5] Added ability to change -fps -minvideo and -maxvideo in the UI
[6] UI gives indication of video creation status
[7] Changed logfile name on startup
[8] Sequential jobs are numbered
[9] Misc bug fixes

Version 5.1.0

[1] Removed the use of M117 messages and replace with M291 messages as this gives much better control.
[2] Set new default, minimum values for -seconds (20) and -poll (10) along with some logic changes to avoid an occassional race condition.
[3] Fixed a code error associated with -extratime
[4] Some minor bug UI / Typo fixes

Version - 5.2.0

[1] Fixed snapshot when called from gcode
[2] Process all M291 messages without delay
[3] Refactored loop control to prevent thread blocking
[4] Prevent first layer capture if -pause yes
[5] Added -password option to support passwords
[6] Released as a plugin for SBC

Code / Detailed Instructions / Documentation are here:

Github

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

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

[jay_s_uk]

@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!

[stuartofmt]

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

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?
