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.
The rotor seems pretty solid. We have not calculated the RPMs but have confirmed it is pulling enough Gs to create a decent DNA pellet at the bottom of a test tube which is why we made it. Future modifications may include a means to measure and also set RPMs/Gs.
We won't be doing any other rotor configurations unless the need arises, mainly because of the potential of failure increasing with complexity when 3D printing.
We always operate it with the lid closed just in case!
