notifications upon start/pause/finish of print

Nxt-1

@torin I don't know if you planned on maintaining this app, but it sure would be nice if it received an update.
I did some testing and got a contineous stream of JSON parse errors. After checking the sources it seems the program uses the GET /rr_status way of talking to the Duet. However, according to this page on the Duet Github, it is deprecated now.

Should you decide to maintain it, I could make time to help out testing.

@nxt-1 getting the similar errors via windows

"2022/06/21 14:23:53 Error while downloading rr_status: Too many errors, resetting counters and stoping track operation. Will hide consequent errors..."

Any chance there's a fix for this @Torin ?

Thanks,

Nate

Torin

@madeinta1wan This is due to API changes introduces in RRv3. There's a chance but it requires few hours of work which I currently do not have, however I will try to squeeze that in somehow. The code is opensource so if someone would make an PR I will happily merge it.

chrishamm

@madeinta1wan @madeinta1wan rr_status is still supported in standalone mode AFAIK. We will add a support layer for rr_ requests to SBC mode in v3.5 but I'm afraid it won't support rr_status. If possible, I'd strongly recommend upgrading to rr_model which returns portions of the object model.

Torin

So I finally found some time and resurfaced my duet enabled printer so I have started updating the app.... So hopefully soon there will be something to show

@chrishamm How do I currently identify finished print? Previously it was in rr_status marked as 'I'(capital I), now I can see see only in rr_model?key=state status: idle, pause, printing.

chrishamm

@torin Those letters are abbreviations for the different machine states (see here), so idle is equal to I.

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.

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

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.

@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?
