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 wheel is designed to self center when released. Tolerances are tight so your printer needs to be well calibrated [a 20mm calibration cube should be +-.03mm]. A worn out thumbstick might not have the strength to spring back.
