Printing progress

[dragondgold]

Would it be possible to get the printing progress (0.0% to 100.0%) using octocmd status?

[vishnubob]

Maybe, does OctoPrint provide this information via the API?

[dragondgold]

Yes, it should be possible !http://docs.octoprint.org/en/master/api/datamodel.html#progress-information I would do it myself but I am new at python and I still don't understand how you use the rest API to communicate with octoprint

[vishnubob]

Sounds to me like a perfect project for you to get to know python! Good luck, and I look forward to your pull request.

[dragondgold]

@vishnubob I'm slowly understanding your code and I successfully done some GET request to obtain print progress and some other data. The problem is with POST request. Apparently I have to specify the Content-Type to application/json otherwise I get Response [500]. I tried to add it to the post method inside OctoPrint_API so I call self.session.post(self.url + url, args=args, headers={'content-type': 'application/json'}) but I get Response [400] on that way.

Can you give me some hint about what I'm doing wrong?

[vishnubob]

ok, i've updated the code a bunch. the problem is octocmd and octoprint have drifted somewhat. there are still some problems, but check out the new code and see if you have you still get a 400.

When trying to run a POST now I get:

TypeError: string indices must be integers, not str

When I debugged the code self.config was just a string containing the path to the config file. Also if I run octocmd init:

Traceback (most recent call last):
  File "/Users/andrestorti/Copy/Impresora 3D/Control Externo/octocmd/scripts/octocmd", line 514, in <module>

    self.location = "sdcard" if kw["sdcard"] else "local"
KeyError: 'sdcard'

There seems to be a problem with the new sdcard option

[vishnubob]

I'm not sure why you got these errors, but I pushed some changes that might address them. Please try it again, and let me know if it works.

[dragondgold]

GET works great but still having issues with POST. I'm just adding this inside OctoPrint_API

    def pause_job(self):
        res = self.post("control/job", data={'command': 'pause'})
        return self.check_response(res, 204)

I'm getting this error:

I'm running this with Python 2.7.10 on OS X Yosemite. The errors with the init command are fixed however.

[vishnubob]

What is the command line you are executing?

[dragondgold]

I added a pause command. I'm just running this:

op = OctoPrint_API(**args.__dict__)
res = op.pause_job()

Here is the complete code if you want to see: http://pastebin.com/LXYRhGHk.

[vishnubob]

Thanks for the code, but I was asking how you were executing the command from the shell.

[dragondgold]

Hooo, I'm running it inside PyCharm!

[vishnubob]

I've never used PyCharm, and since this is written as a command line tool, I can't really help you without an analogous command line example that replicates your results.

[vishnubob]

Reading your code further, it doesn't seem like you execute load_config(), which is why you are getting the error. Notice that the status command loads the config. If you model your command based on this, it should work. Good luck.

[e77]

status command should have a -continuous switch where it just polls every couple of seconds.

octoprint-cli does this, so it shouldn't be too hard to achieve.

progress %age, current layer number, Z height would also be useful additions to the output
