Octoprint API: command output


I am building a custom web interface using the JS API.
I can successfully use it but i can't find how to get the reponse of the /api/printer/command service.
For example i want to get the result of the M420 V gcode (Bilinear Leveling Grid detail)
From the doc, it only can return a 204 reponse ( or a jQuery Promise if using the JavaScript Client Library)
Thanks for help!


Because commands are queued in OctoPrint I don't think you'll get what you're asking for. The only thing I think that comes close is the push updates.


Sorry for dekay,thanks for the answer jneilliii
You are right, gcode instruction sends seem to be in asynchronous mode. I ll see maybe if i can make a octo plugin who can give the cmd output
