If you are using the MPCNC with a 3-D printer (FDM) head then Octoprint.org should work fine. If you have a cutting tool (router, Dremel, spindle) on the MPCNC then you need software that understands various size and shape tools and how to create objects by removing material rather than adding it. They are very different problems. That’s what drives the need for ESTLCAM or similar software.
