MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Have you tried to see if the largest parts will fit? I know they do on the ender 3 and its only 10mm smaller.
I would never discourage someone from trying something new but I would think it would be beneficial to have some experience with troubleshooting printers or at least building a printer kit before you took on this project. I did start a Mostly Printed 3D Printer Facebook group so if you do run into issues or have questions I'm sure someone in the community would be happy to help you out.
