Hi,

I have a plan on building a 3D Printing Farm, using an ERP software, OctoPrint and Node-RED.

Is it possible to use Node-RED to trigger/click the 'Start Print' button on OctoPrint?

I was thinking of using the 'http request' node  
GET request (to retrieve the octoprint webpage)  
POST/PUT request to trigger or click the print button)

Would the above method work?

Thank you

> Hi, I have a plan on building a 3D Printing Farm, using an ERP software, OctoPrint and Node-RED. My main focus right now is to integrate Node-RED with OctoPrint, more specifically using Node-RED to trigger/click the 'Start Print' button on OctoPrint. I was thinking of using the 'http request' node together with a GET request to retrieve the OctoPrint website and then either PUT or POST requests to start the printing. I have no idea whether that would work. Opinions and alternative solutions …
