notifications upon start/pause/finish of print

Torin

@chrishamm Many thanks for that, it definitely extends what I've seen.
However I am missing a 'final status' if that makes sense e.g. there's the status for cancelling yet there's no cancelled status or processing and no processed which makes it hard to understand and put the proper function in place to determine final status without hammering the API and making a request every let say 100ms which could still lead to some false positives.

This may help. Its some of the logic in DuetLapse3. It ends up being a bit convoluted .... and of course I have a bunch of defensive coding in here (for other reasons).
The main logic starts at line 16.

Any yes - it can do with a bit of tidying up

def captureLoop():  # Run as a thread

    global printState, duetStatus, captureLoopState
    
    if connectionState is False:
        return
    
    captureLoopState = 1
    printState = 'Not Capturing'

    lastDuetStatus = 'idle' # logical state on start of each thread instance

    logger.debug('Starting Capture Loop')

    while captureLoopState == 1:  # Set to 0 to stop. e.g  By http listener or SIGINT or CTL+C
        if duetStatus != lastDuetStatus:  # What to do next?
            logger.info('****** Duet status changed to: ' + str(duetStatus) + ' *****')
            # logical states for printer are printing, completed
            if duetStatus == 'idle' and printState in ['Capturing', 'Busy'] and terminateState != 1:  # Capturing is finished without being commanded
                printState = 'Completed'
                logger.debug('****** Print State changed to ' + printState + ' *****')
            elif duetStatus in ['processing', 'idle'] or (duetStatus == 'paused' and detect == 'pause'):
                printState = 'Capturing'
                logger.debug('****** Print State changed to: ' + printState + ' *****')
            elif duetStatus == 'busy':
                printState = 'Busy'
                logger.debug('****** Print State changed to: ' + printState + ' *****')
            else:
                printState = 'Waiting'
            logger.info('****** Print State changed to: ' + printState + ' *****')

        if printState == 'Capturing':
            oneInterval('Camera1', camera1, weburl1, camparam1)
            if camera2 != '':
                oneInterval('Camera2', camera2, weburl2, camparam2)
            unPause()  # Nothing should be paused at this point
        elif printState == 'Completed':
            logger.info('Print Job Completed')
            printState = 'Not Capturing'
            # use a thread here as it will allow this thread to close.
            startnextAction('completed')
            break # Do not want to wait to end

        if captureLoopState == 1 and terminateState != 1 and connectionState:  # If still running then sleep
            lastDuetStatus = duetStatus
            time.sleep(poll)

    printState = 'Not Capturing'
    captureLoopState = -1
    return  # End of captureLoop

Hey folks,
I want to share a download link with the version that should now work with v2 and v3 API.
If you could test it and let me know if it's all good that we'd be great and I will release it officially.

Only change you need to make is additional entry in your configuration file adding api_version in the connection section(v2 or v3) e.g.:

connection:
  host: 192.168.0.11
  polling_time: 30
  error_count: 5
  api_version: v3

Without further ado:
https://1drv.ms/u/s!Aq3gq6mIQqpsisE-e3Adz3wsP6dAJw

Link is going to expire in 2 weeks, after that I will just merge it

@torin

Don't know if this is interesting for you but may avoid having the user input the version /model info. Its Python, but the logic will be the same.

def getDuetVersion(model):
    # Used to get the API and version information from Duet

    if model == '' or model == 'rr_model':
            URL = ('http://' + duet + '/rr_model?key=boards')
            r = urlCall(URL, 3, False)
            if r.ok:   #The API type is rr_model
                try:
                    j = json.loads(r.text)
                    version = j['result'][0]['firmwareVersion']
                    return 'rr_model', version
                except:
                    pass

    if model == '' or model == 'SBC': 
            #  model = '/machine/status'
            URL = ('http://' + duet + '/machine/status')
            r = urlCall(URL, 3, False) 
            if r.ok:
                try:
                    j = json.loads(r.text)
                    version = j['boards'][0]['firmwareVersion']
                    return 'SBC', version
                except:
                    pass

@stuartofmt Cool. I'll have a look tomorrow (that is if I will survive tomorrow heatwave...). Cheers buddy.

@torin

Ha! - good day to be indoors and futzing with play code
Good Luck. BTW what programming language are you using?
Part of the reason I ask is that I also have some code for using gmail.

I don't actually use your program as I use DuetMonitor (which only supports gmail) - but it you wanted to extend your connection capabilities - I can sling it in your direction.
I

Torin

@stuartofmt Ah that's quite cool. I've already put that in, however I stripped in my case and just checked for the appropriate content-type header on each URL, in both cases it should be app/json, otherwise it's just wrong.
I'm doing it all in golang, since it's quite nice for such nice things and portability and lack of dependencies.
I have notifications for any email service assuming it can do smtp so should in theory work everywhere. Can you point me to this duetmonitor? First time I'm hearing about this and haven't seen it.

If you want to poke around code and see what's there, that's the current that will go to master soon.

@torin I tried the new version but could not get past identifying v2 of v3 firmware.

Printer is a Duet3 6HC in SBC mode, attached to a Jetson Nano (arm64). That name Nano also runs your project.

Top of rrnotity.yaml looks like this (dwc is running on port 8080)

connection:
  host: localhost:8080
  polling_time: 5
  error_count: 50
  api_version: v3

Running the rr_notify results is this output:

2022/07/19 00:40:18 Detecting API version... 
2022/07/19 00:40:18 Couldn't identify v2 or v3 firmware
panic: Couldn't identify v2 or v3 firmware

goroutine 1 [running]:
log.Panicf({0x463b71?, 0x454fd0?}, {0x0?, 0x1?, 0x400022a030?})

main.main()
	/builds/Toriniasty/reprap_notify/cmd/rr_notify/main.go:71 +0x46c

I am not sure how to proceed from here or how to debug. ¯_(ツ)_/¯

@nxt-1 hiya, would you be able to provide me output from these two commands(run from the nano itself):

curl -v http://localhost:8080/machine/system
curl -v http://localhost:8080/rr_model?key=boards

?

Nxt-1

@torin They result in a 404 for both, though I would not be able to guess why since the base address does seem to be reachable, though understandably complaining about the lack of JS.

@nxt-1 Right, so the second paste is wrong and missing URI and I had a thought as well, since there's '?' in URI bash might be screwing around with it try again with:

curl -v http://localhost:8080/machine/system
curl -v "http://localhost:8080/rr_model?key=boards"

I did in fact ment to post it without URI, just to show that can I fact make a connection.

Here's the two requests, as requested

@nxt-1 That's bit odd according to the previous post it should be either one of those two URLs.

@stuartofmt / @chrishamm any idea why either doesn't work?

chrishamm

@torin It's /machine/status, not /machine/system. Support for rr_ requests will come in v3.5.

Torin

@chrishamm Awesome, thanks for the great spot, not sure how I missed it.

@Nxt-1 would you mind giving it another go please? also api_version not needed anymore, software will try to detect it automatically.

Nxt-1

@torin /machine/status does give me a wall of json output .

However launching the updated executable I get continous json errors:

@nxt-1 Interesting, can you provide me full curl of:

curl -v 'http://localhost:8080/rr_status?type=3'
curl -v http://localhost:8080/rr_fileinfo

(those two below probably will not work)
curl -v 'http://localhost:8080/rr_model?key=job'
curl -v 'http://localhost:8080/rr_model?key=state'

Which makes sense, since Chrishamm mentioned the rr_ system wil be introduced in v3.5

@Torin So, it's been a while. I finaly broke down and installed a Go environment so I can play around with your project.

What I belive is going on is that there is rrf3 and 2, which your latested beta does differentiate between, though not entirely correct. Within rrf3 a subdivision must be made between the SBC version and the standalone version. The standalone version (rrf3) will get detected as is and work as intended (I assume I cannot test this). Rrf2 will also work I believe (again, I cannot test this). However, SBC mode (rrf3) will not work since it uses the /machine/status syntax which will lead it down the rrf2 branch of your code. That wont work as rr_status is deprecated and returns resulting in a empty response. Which is obviously not json parsable, hence the continuous json errors I reported earlier. @chrishamm please correct me if I am wrong at any point here.

What I belive needs to change to make all of this work:

Expand the api version check in main to handle rrf3 sbc as a separate case (or pass the version/type as a config parameter again)
Make a 3rd handler for rrf3 sbc that uses /machine/status to get the full object model and takes the data it needs from it
-> I've changed the v2handler to package for now as an example on how this could work, check the files attached below

Some other changes I think would be useful if added:

Make the connection protocol part of the host parameter. I.e. add the http part in there as well. For example my machine normally does not listen to http requests so making this user changeable would save some hassle on my side
Add the same delay to the loop in case of errors, so the loop does not run at mach3

======================
Example implementation for rrf3 sbc handler (currently sits in place of the v2 handler)
v2_handler.gcode
types.gcode
