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.
Getting NEMAs to ToyREP is not that easy. It was never designed for this and such upgrade would require many new plastic parts (almost all of them).
It is probably too soon to shout this loud, but there will be (probably, one day) a new version of ToyREP 2, that will be able to use 28BYJ-48, NEMA 17 and probably NEMA 14 too. I am still skeptical about NEMA 11 and smaller, as it is too weak to drive 3D printer (but with new version such upgrade would be possible to). I am waiting for some part from China right now so I can continue on this project.
