Execute script after gcode is saved to disk

Recommended Posts

Posted · Execute script after gcode is saved to disk

Hello all,

 

How could I go about executing a script when a gcode file has been generated?

 

My case is that I have a WiFi SD card and I would like to be able to automatically upload the file to it once it's been saved. This has to be done with an HTTP request that I can easily put in some script, but unfortunately, I couldn't find a way to hook a script to Cura.

 

Any ideas on how to achieve this are very welcome :)

 

Thanks

Try the PostProcessingPlugin Extension.

I've implemented a post processing plugin that does very similar thing - except is for post processing a gcode with a cloud function.

Here's the installation instruction:

And here's the code that uploads the generated file to the code:

The more "official" way to do what you describe is to write an OutputDevicePlugin.

See https://github.com/Ultimaker/Cura/wiki/Plugin-Directory and specifically https://github.com/Ultimaker/UraniumExampleOutputDevicePlugin

 

That way you would not have to create an intermediate file on disk, but just send the gcode to your http connection.

 

For inspiration you might also want to check out http://github.com/fieldOfView/OctoPrintPlugin which sends gcode to OctoPrint over an HTTP connection, but that is a rather bigger plugin (that also provides monitoring).

 

A postprocessing script could work in some cases, but is really meant for something else. It does not give you access to the gcode file (just the raw gcode as a string), and is actually run *before* the gcode is handed over to an OutputDevicePlugin.

Hey @ahoeben,

Thanks, that seems the better way to go since it won't be a "hacked" approach.

 

@BoostedGcode

Thanks for the example. It can prove useful if the OutputDevicePlugin doen't pan out.
