Is there a way to configure and start Buildbotics CNC Controller program through Linux command-line (through SSH ) or API? I have tried to find any relevant information but failed so far. What I am looking to do is to configure and command stepper motors-based motion platform (potentially controlled by Buildbotics CNC Controller) through external (network connected) Linux-based system from command line or Python scrip level.
There seems to be Buildbotics API over HTTP (http://dev.buildbotics.com/) however its documentation does not mention specifcally any "Program" related commands.

Re: Command-line control
It is possible to control the Buildbotics controller over HTTP. It's not documented but this is how the Web frontend works. dev.buildbotics.com is the API for our project sharing Website and is unrelated.
The HTTP entrypoints can be found listed in Web.py. For example, to start the currently selected GCode program you would do a PUT to /api/start. You can upload GCode with a muli-part form PUT to /api/file/. It would be pretty easy to do this with the Python requests library.
For example, with curl:
To get status information, you need to open a Web socket connection to /websocket or /sockjs and listen to the JSON messages that are sent across it. This code in CAMotics does exactly that using Qt: https://github.com/CauldronDevelopmentL ... trlAPI.cpp
We will document this API eventually. I've opened a new issue on GitHub to track this request: https://github.com/buildbotics/bbctrl-f ... issues/201

Also looking to control from a computer through SSH or http,
Is there a document or example to follow.

Tried

I get the following error.

Re: Command-line control
I have straightforward remote upload and job starting working in python here.
At this point, I'm trying to figure out how to poll job status. Looking at the source for the Onefinity WebUI, it loos like it should be part of the state object, but I can't figure out how to get that object. Looking at the handler definition takes us to the StateHandler which really looks like it wants a GET request, but it's not working for me. If I GET /api/state, I get a 404 (Not Found) back and if I try to PUT /api/state, I get 405 (Method Not Allowed).
Watching /api/log during a job, I can see some of the information that I want on Comm entries, but not on Web entries. The log doesn't have all of the info though -- for example, I see the state change to RUNNING in a hash keyed xx, but I don't see the state change back to READY when the job completes. There has to be a proper way to get the state as it's there in the WebUI, but I'm going cross-eyed sorting through the JS. In the meantime, I'll probably wind up polling the log and assuming the job is done when the log stops updating for a few poll intervals.
