Jon00 OctoPrint (3D Printer Interface) For HomeSeer 3

[jon00]

Octoprint is a free, open-source program to control and monitor a 3D printer via its web interface. Normally run on a Raspberry Pi, it has a built-in API which provides access to a number of metrics about the 3D printer. This script polls the API to update a number of virtual devices which can be used to trigger events.

Example uses:

» Switch off the 3D printer when the print has been completed.
» Switch off the 3D printer if the nozzle or bed temperatures exceed pre-set limits.
» Switch on the 3D printer/ventilation systems etc when a GCode file is uploaded to Octoprint.
» Automatically change ventilation methods etc using the GCode filenames.
» Send emails/Push messages detailing progress/pause/completion etc.

Images from the Webcam is supported (if installed).

Basic control of the printer is also provided.




As always, it is available from my site (click on my banner below).

Jon00,

I got an issue with this script, it result in all de3vices created and some are filled with data, but some are not and the following entry in my log;

Jon00_Octoprint

Error at Main Block 30 Arithmetic operation resulted in an overflow.

mrt-13 14:21:56

Jon00_Octoprint

Error at Main Block 29 Arithmetic operation resulted in an overflow.

I Also see 1000% instead of 100% probably a regional settings issue?


Regards

Bart

The error points to a time format issue.

The script should populate an additional ini file (Jon00OctoprintData.ini) with all the data. Would you post that please.

for example at this moment its printing, and gives a completion of 1591752593882251% but it should be 15.91752593882251, so i guess there is also an issue with regional settings, which are dutch. decimal is (,)

[jon00]

Thanks. It looks like Octoprint is not respecting regional settings via its API hence the . for decimal values. I'll PM a new version which replaces it with your regional character to see if that helps.

[bartbakels]

Thanks, that did the trick!

great support as always

[jon00]

Good to hear!

V1.0.1 is now posted on my site.

[ServiceXp]

Will this plug-in work for multiple Printers?

[jon00]

Yes, it will support multiple instances of Octoprint running.

Any chance we could get configuration options for the webcam? I'm getting the following log error

Jon00_Octoprint Webcam: ERROR: The remote server returned an error: (404) Not Found

Most likely as I'm running Octoprint on Windows 10 with my webcam on a non-standard port. Octoprint is aware of the webcam config and is displaying it fine, BTW.

.

[jon00]

Under [Settings] add:

WebCamPort =XX

where XX is the Camera port number.

[mterry63]

Thanks for the prompt response. In retrospect, the port must be right otherwise there wouldn't be a 404 error in the log, as that implies it reached the server successfully. The webcam is using http://192.168.x.x:8000/camera/jpeg as the snapshot URL, is that what the script is looking for? Can we specify the URL?

[jon00]

You cannot specify the entire address as I linked it to the WebAddress entry in the ini file.

If that is the same then you can add this also under [Settings]:

WebCamURL=/camera/jpeg

[mterry63]

Jon, sorry for the back and forth. The Webcam is running on the same host as Octoprint, so that's OK.
The Octoprint log shows the original URL request, which wasn't valid in my case as I suspected.

409 GET /api/printer (192.168.x.x) 4.00ms
WARNING - 404 GET /webcam/?action=snapshot:8000 (192.168.x.x) 3.00ms

I added the exact config line you stated and now the HS3 log says:

Webcam: ERROR: The given path's format is not supported.

And no hits to the Octoprint log.

[jon00]

I don't believe the port number should be part of the URL.

See if this works:

WebCamPort =8000
WebCamURL=/webcam/?action=snapshot
