Smoothie allows you to use a probe to do a variety of things : 

  • Calibrate machine geometry, for example for delta machines
  • Automatically level un-even or non-level surfaces, using either grid or three-point methods
  • Automatically find the distance between the tool and either the workpiece or the build surface
  • Automatically detect tool lengths

To learn more about probing with Smoothie, read the zprobe module documentation.
